Jandy® Pro Series, Hi-E2® and Hi-E2®R Gas-Fired Heater | Installation & Operation Manual
Section 1. General Information
1.1Introduction
This manual contains information for the proper
installation and operation of the Hi-E2 and Hi-E2R Model
EHE pool/spa heater. Certain sections are specific to
United States or Canadian installations, and are labeled
United States or Canada. Procedures in this manual must
be followed exactly. To obtain a copy of this manual
contact Zodiac Pool Systems, Inc. ("Zodiac®"). For
address information. See back cover.
1.2Description
The Hi-E2 Low NOx heater is a very efficient gas-fired
pool and spa heater. Its combustion system includes a
heat exchanger which extracts 95% of the energy in the
gas fuel. It has no standing pilot burner. It exceeds the
requirements of energy conservation regulations such as
those in California, Hawaii, New York, Oregon and other
states which require that a pool heater have intermittent
ignition.
The heater is designed to operate in conventional
swimming pool and spa equipment arrangements. It
requires 115V 60 Hz electrical power. It has the versatile
dual-thermostat control system for pool/spa combinations.
The Hi-E2 is certified by CSA International to comply with
latest editions of applicable standards. In the United States,
the applicable standard is ANSI Standard Z21.56 for gasfired pool heaters. In Canada, it is Standard CSA 4.7.
The Hi-E2 Low NOx heater has been designed specifically
to heat fresh water swimming pools and spas, and with
proper installation and care, it will provide years of
reliable service. Do not use it to maintain pool or spa
water temperature below 70°F. Do not use it as a heating
boiler or general service water heater or to heat salt water.
For special applications, consult your Jandy Pro Series
dealer.
1.3Warranty
The Hi-E2 is sold with a limited factory warranty. A copy
of the warranty is included in a plastic bag inside the
heater. The warranty does not cover damage caused by
improper installation, operation, or field modification; or
damage to the heat exchanger caused by corrosive water.
See Section 3.4 for guidelines on pool water chemistry.
WARNING
Improper installation or maintenance can cause nausea
or asphyxiation from carbon monoxide in flue gases
which could result in severe injury, or death. For indoor
installations, as an additional measure of safety, Zodiac
Pool Systems, Inc. strongly recommends installation of
suitable Carbon Monoxide detectors in the vicinity of this
appliance and in any adjacent occupied spaces.
AVERTISSEMENT
Une installation ou un entretien inadéquat peut causer
la nausée ou l’asphyxie en raison du monoxyde de
carbone présent dans les gaz de combustion et même
entraîner des blessures graves ou la mort. Pour les
installations intérieures, comme mesure de sécurité
additionnelle, Zodiac Pool Systems, Inc. recommande
fortement l’installation de détecteurs de monoxyde
de carbone près de cet appareil ainsi que dans les
espaces adjacents occupés.
Section 2. Installation Instructions
2.1
General Requirements
All gas-fired products require correct installation to assure
safe and satisfactory operation. The requirements for pool
heaters include the following:
1.
2.
Appropriate site location and clearances.
Sufficient supply of clean air for combustion and
ventilation.
3. Proper venting of products of combustion.
4. Properly sized gas pipe.
5. Properly sized gas meter.
6. Adequate water flow.
7. Provision for disposal of combustion condensate
water.
In the United States, installation must be in accordance
with local codes and the most recent edition of the
National Fuel Gas Code, ANSI Z223.1/NFPA-54. The
Code can be obtained from:
National Fire Protection Association
1 Batterymarch Park
Quincy, MA 02169
www.nfpa.org
In Canada, install the heater in accordance with local
codes and the most recent edition of the Natural Gas and
Propane Installation Code, CAN/CSA B149.1.
Special Precautions
Liquefied petroleum (LP) gas is heavier than air.
Therefore, a pool heater using LP gas is subject to special
installation rules. Consult local codes and fire protection
authorities about specific installation restrictions.
Fuel gas and its combustion products are known to cause
cancer or harm the reproductive process. Follow these
installation instructions and applicable codes exactly to
avoid this.
Jandy® Pro Series, Hi-E2® and Hi-E2®R Gas-Fired Heater | Installation & Operation Manual
2.2
Heater Assembly and Preparation
The Hi-E2 can be installed in a variety of ways, some of them
requiring preparation or assembly in the field. In all cases,
condensate tubing and fittings, which are provided with the
heater, must be connected and routed. Water connections are
provided on the right side of the heater but can be changed to
the left side by reversal of the water headers.
It is best to handle these preparations before the heater
is in its final location. Instructions are provided in
subsequent sections of this document.
Installation at High Elevation
The Hi-E2 has a venturi-type combustion system which
does not require modification for operation at high
elevation. In this type of system, air and fuel gas density
changes are automatically compensated for, assuring
proper air/fuel mixture. Heating capacity is reduced about
3 percent per 1000 feet (305 meters) above sea level. In
general, efficiency at high elevation is equal to or better
than at sea level.
2.3
Locate the heater in an area where water leakage will
not result in damage to the area around the appliance or
to a structure. If forced to locate the heater where water
leakage may cause damage, provide a suitable pan with
drain under the heater. This pan must not restrict air flow
or heater functions.
In selection of a location, disposal of combustion
condensate must also be considered. The heater can
produce three gallons of condensate water per hour
under some operating conditions. Means to drain this
condensate must be available or special provisions, such
as a condensate pump must be provided. See later section
on condensate disposal.
2.4
Table 1.
CAUTION
When pool equipment is located below the pool
surface, a leak from any component can cause large
scale water loss or flooding. Zodiac Pool Systems, Inc.
cannot be responsible for such water loss or flooding
or resulting damage.
ATTENTION
Lorsque l’équipement d’une piscine est situé sous la surface
de l’eau, une fuite provenant de n’importe quel élément
peut causer une perte d’eau importante ou une inondation.
Zodiac Pool Systems, Inc. n’est pas responsable des
pertes d’eau, des inondations ou des avaries causées par
une installation ou un entretien inadéquat.
Installation Clearance Requirements.

The Hi-E2 may be installed indoors or outdoors as outlined
in later sections. When installed indoors, combustion
air will often be piped to the heater and this requirement
may affect the choice of location, see later section on air
for combustion and ventilation. Both indoor and outdoor
installations require provision of means for disposal of
combustion condensate per section 2.8.
When pool equipment is located below the pool surface,
a leak from any component can cause large scale water
loss or flooding. Zodiac Pool Systems, Inc. cannot be
responsible for such water loss or flooding or resulting
damage. Location of the heater below or above the pool
deck affects operation of its water pressure switch. See
sections on water piping and heater start-up for more
information about this.
Installation Clearances
Clearances between the heater and combustible material
must be per Table 1.
Heater Location
Install the heater at least 5 feet (1.52 meters) from the
inside wall of the pool or spa unless the heater is separated
from the pool or spa by a five-foot (1.52 meter) high solid
fence, wall or other permanent barrier.

These clearances are the minimum acceptable. Whenever
possible, larger clearances should be provided to assure
adequate room for service operations. Note that gas piping
must be provided through the left side of the unit and
that the combustion air duct, when provided, also enters
through the left side. See later section on combustion air,
and also the section on water piping.
Do not install the heater on carpeting or similar material.
2.5
Outdoor Installation
Locate the heater in an open, unroofed area and maintain
the clearances shown in Table 1. Do not locate the heater
below or adjacent to any doors, windows, louvers or
grates, etc., which connect in any way with an inhabited
area of a building, even through another building such as
a garage or utility room, see Figure 1. Do not locate the
heater below an outdoor deck, unless treated as an indoor
installation with adequate clearances and proper venting
to a location away from the deck.
If the heater is installed close to a structure, protect it from
rain water runoff by means of gutters, roof water diverters
or similar measures. Do not locate the heater close to
irrigation sprinklers. Water from sprinklers may damage
controls and electronic components.

Because the Hi-E2 is very efficient, combustion system
exhaust gases are moist. Do not locate the heater such
that this exhaust will impinge on structures or vegetation
which may be damaged by combustion condensate.
WARNING
United States
Do not install the heater with the top of the vent
assembly within 4 feet (1.22 m) horizontally, 4 feet
(1.22 m) below or less than 1 ft (300 mm) above of any
opening into a building.
Canada
Do not install the heater with the top of the vent
assembly within 10 feet (3.05 m) of any opening into a
building.
AVERTISSEMENT
Lorsque vous installez l’appareil de chauffage,
assurez-vous que l’ouverture d’aération se trouve à un
minimum de 10 pieds (3.05 m) de toute ouverture d’un
bâtiment.
In Florida it is required that the heater be securely
fastened to the equipment pad. Use a size 1/4” x 2-1/4”
long galvanized or plated concrete screws and washers
at each of the four (4) tabs located at the base of the
heater. Mounting the appliance in this manner meets the
applicable requirements of the Florida Building Code.
Mounting screws are not provided with this heater. After
placing the heater on the equipment pad, drill a hole in
the concrete at each of the four (4) tabs on the feet of the
heater. (The correct size drill bit is usually provided with
the concrete screws when purchased). Place a screw in
each of the holes and fasten the heater to the equipment
pad, see Figure 2. Do not over torque the screws.
2.6
Outdoor Shelter Installation (Canada)
2.7
Indoor Installation
An outdoor shelter is an unoccupied enclosure which
does not communicate directly with occupied areas.
The Hi-E2 may be installed in such a shelter only when
the installation is in accordance with local codes and
the most recent edition of the Natural Gas and Propane
Installation Code (CAN/CSA B-149.1). These codes and
standards and Zodiac® require that the heater be properly
vented as outlined in this manual. Other requirements also
apply, such as provision of ample uncontaminated air for
combustion and ventilation.
The Hi-E2 can be located indoors when provided with
“one-pipe” or “two-pipe” systems for combustion air
and combustion product venting. A one-pipe installation
has only a vent pipe, and air for combustion must be
provided to the room the heater is located in. A two-pipe
system (sometimes referred to as “direct vent” or “sealed
combustion”) has a vent pipe plus a pipe bringing air
directly to the heater's combustion system.
Section 2.7.2 specifies requirements for provision of
combustion and ventilation air for one-pipe installations.
Section 2.7.3 covers two-pipe installation.
An important consideration in selecting one (1) or two
(2) pipe installation is the quality of the combustion
air. Indoor air is sometimes contaminated with various
household or pool sanitation chemicals which can cause
corrosion in the heater combustion system. Unless the
indoor air is known to be free of these materials, two (2)
pipe installation is strongly recommended.
2.7.1 Preparation of Heater For Indoor Installation
If the Hi-E2 is to be installed indoors, its exhaust discharge
grille must be converted to an exhaust pipe configuration.
The necessary vent collar, gasket and screws are shipped
packaged within the heater. The conversion can be done
quite simply as follows. See Figures 3 and 4:
Jandy® Pro Series, Hi-E2® and Hi-E2®R Gas-Fired Heater | Installation & Operation Manual
1.
Remove the vent exhaust grille by removing the
four (4) screws which retain it. The grille, its
gasket, and the screws may be discarded.
2.
Place the vent collar gasket on the top of the
heater aligning its center hole and screw holes
with those in the top of the heater.
3.
Place the vent collar over the gasket and fasten
it in place with the screws and lockwashers
provided. Be sure that all components are
properly aligned. Screws must be tightened
enough to assure a sealed joint without deforming
the vent collar.
2.7.2 Combustion Air Requirements for One-Pipe
Installation
One-pipe indoor installations must have specific
provisions for supply of combustion and ventilation air
to the room in which the heater is located. Two (2) air
openings must be provided — one (1) near the ceiling
and one (1) near the floor. When air is provided directly
through an outside wall, each opening must have at least
1 square inch (6.5 square cm) of area per 4000 BTU/h of
Page 7
ENGLISH
heater input. When air is provided indirectly through ducts
from the outside, the openings and passages must have
at least 1 square inch of area per 2000 BTU/h of heater
input. These requirements are interpreted in Table 2.

Note that the numbers indicate the net free area —
after allowing for the blockage of grille bars, etc. See
applicable local codes and the previously-cited national
codes for details. Even though codes may permit it,
Zodiac® does not recommend installations with only
“infiltration” as the means for provision of combustion air.
See Section 2.7.3.3 for vent pipe sizing.
WARNING
Do not store any chemicals, cleaners, or other corrosive
material near combustion air openings or in the
room. Avoid locating appliance vents in the vicinity of
combustion air openings. Failure to prevent corrosive
materials from mixing with combustion air can result in
reduced heater life and unsafe heater operation.
AVERTISSEMENT
Ne pas entreposer ni utiliser d’essence ni d’autres
vapeurs ou liquides inflammables à proximité de cet
appareil ou de tout autre appareil.
Figure 3. Removal of outdoor exhaust grille.
2.7.3 Two-Pipe Installation (Direct Vent)
This section specifies installation requirements
for combustion air and vent piping for “two pipe”
installations. A two-pipe system provides isolation of the
Hi-E2 combustion system from the space in which the
heater is installed. It has not only a vent pipe, but also
a combustion air pipe to provide air directly from the
outdoors. Research studies have shown that contaminants
which may corrode internal heater parts are typically at
much lower levels in outdoor air than in air from indoors.
2.7.3.1 Connection of Combustion Air Pipe
A collar for combustion air pipe connection is provided in
the heater at the inlet of the filter box. As shown in Figure
5, the combustion air pipe is routed through the side of the
heater to the filter box connection. Remove the cover plate
from the left side panel to provide access for the air pipe.

Air and Vent Piping
To avoid risk of property damage, serious injury, or
death, use ONLY piping materials from the list below
which are certified or listed for the application per
the requirements of UL 1738 and/or ULC S636, by a
Nationally Recognized Testing Laboratory (NRTL).
Piping for combustion air and venting must be large
enough to avoid restriction of the heater combustion
system. Pipe diameter, number of elbows and length of
pipe determine how much it restricts flow to or from
the heater. Also, a large heater requires larger pipe than
a small heater because it operates with higher flow of
combustion air and exhaust products. Table 3 specifies the
allowable length of piping for various situations.
AVERTISSEMENT
Pour éviter le risque de dommage matériel, de
blessure grave ou de mortalité, utiliser UNIQUEMENT
les matériaux de plomberie de la liste ci-dessous
qui sont certifiés ou répertoriés pour l’application

The combustion air inlet opening must face downward
to prevent entry of rain or snow. The vent outlet must
discharge away from the combustion air inlet - normally
in a horizontal direction when on a wall and vertically
upward when on a roof. Both should terminate at least
12" (30.5cm) above the snow accumulation level. In
locations with freezing climate, extension of the vent pipe

outside of the building should be minimized. The insect
screens provided with the heater must be installed at the
combustion air and vent pipe openings as shown in Figure
10. Insect screens are sized to fit the inside of a 5" PVC
pipe fitting. Trim them as necessary for smaller pipe sizes.
Connect the vent pipe to the heater vent collar with an airtight corrosion-resistant clamp. The connection must not
allow leakage of combustion products into the space but
should be removable for service. See Figure 7.
Connect the combustion air pipe to collar of the air filter
box. For this combustion air pipe only, sheet metal pipe is
most convenient and can be screwed directly to the collar.
Seal the joint with silicone sealer or similar mastic material.
Install vent piping with a continuous rise of at least 1/4"
per foot (20 mm per meter) away from the heater. This will
assure that any condensate forming in the vent pipe will
flow back to the heater where it can be disposed of properly.
If the Hi-E2 is being installed to replace an existing pool
heater, it is recommended that a new appropriate venting
system be installed with the new heater. However, if
an existing venting system must be used, be sure to
carefully inspect the venting system to ensure that it is
in good condition and continues to be appropriate for the
Hi-E2 heater. Replace any parts that are not in good and
serviceable condition with new parts before completing
the pool heater installation.
2.8
Condensate Disposal
In a high-efficiency combustion process, combustion
product gases are cooled so much that liquid water is
condensed. Flow of this “condensate” can be quite high.
When pool water is very cold, as much as 2 or 3 gallons
of condensate can be produced in an hour. Condensate is
mildly acidic. Before treatment, its “pH” is typically in the
3.5 to 6.0 range.
Handling and disposal of condensate is not complicated,
but it must be done correctly to prevent problems or
complaints. A trap/neutralizer assembly is provided with
the heater to simplify installation. This assembly is easily
installed in the base of the heater. Figure 11 illustrates its
installation and the routing of drain tubes.
Support vent piping with suitable hangers so its weight
does not bear on the heater or building penetration and
so that piping joints are not strained. Support horizontal
runs at intervals no greater than 6 feet (1.82 meters), and
closer if necessary to avoid sagging. Sagging can trap
condensate water and block the vent.
Both combustion air and vent piping joints must be sealed.
Metal combustion air pipe joints should be fastened with
screws and sealed with permanent sealer or tape. Plastic
vent pipe joints must be made with solvent cement listed
for such use. Joints in 29-4C® stainless steel pipe must
be sealed in accordance with its listing. Connection of
combustion air and vent piping to the heater should be
serviceable — i.e. removable for heater service.
2.7.3.5 Room Ventilation
The room a Hi-E2 is installed in must be provided with
adequate ventilation. Like other gas-fired appliances, the
Hi-E2 releases heat to its environment, and a room with
no ventilation may become too warm.

Jandy® Pro Series, Hi-E2® and Hi-E2®R Gas-Fired Heater | Installation & Operation Manual
To install the condensate assembly, first install the
short length of 5/8" I.D. tubing (Collector Drain) on
the barbed fitting on the bottom of the condensate
collector. Then drop the condensate tray into the opening
in the base pan of the heater, bending the 5/8" tubing as
necessary to get the tube into the tray. Readjust the 5/8"
tubing so that its lower end is 1/4" - 3/8" above the bottom
of the tray. The tray can be positioned with the outlet
fitting to the right, as shown in Figure 11, or with the
fitting to the left, depending on the direction required for
condensate disposal. Connect the piece of 1/2" I.D. tubing
to this outlet fitting and route it out of the heater through
the hole in the side of the base panel. This tube carries
condensate to the drain. If this disposal tube is routed to
the left, remove the plug button from the hole on the left
side of the base panel and push it into the hole on the right
side.
Connect the remaining short piece of 3/8" I.D. tubing to
the barbed tee fitting in the tubing immediately in front of
the blower. Position this tubing so that its bottom end is
1/4"-3/8" above the bottom of the condensate tray. This
tube provides drainage for the vent duct and blower.
A package of limestone gravel neutralizer is provided with
the condensate assembly. Place this gravel in the tray after
installing and properly positioning all tubes. Be sure that a
limestone pebble does not plug any of the tubes. Place the
cover on the tray when this is done.

Gas Supply and Piping
Before installing gas piping, check the rating plate on the
heater to be sure that the heater is for use with the correct
(available) gas. Make sure that gas supply pressure is
adequate per the requirements in Table 4.
It is important that there be no sagging sections of tubing
to trap water. Drainage to the trap and out of the trap
to the drain must be assured by continuous downward
routing of these tubes. It may be necessary to elevate
the heater to provide downward routing. The outlet of
the disposal tube must be open to the air. PVC pipe is
recommended for long drain tubes.
Table 4.
If a gravity drain is not available, a condensate pump
must be provided in the field. Suitable condensate pumps
are available commercially at air conditioning equipment
distributors.
Gas piping must be large enough to provide the required
gas flow rate without excessive pressure drop. Table 5
specifies pipe sizes which will limit pressure drop to 0.5
inches WC (125 Pa), based on the National Fuel Gas
Code, ANSI Z223.1/NFPA-54.
Incorrect installation of the condensate assembly or
tubing can result in overflow or waterlogging of the vent.
In normal operation, water accumulates in the tray at the
level of the outlet fitting, and this provides a “water seal”
which accommodates combustion system pressures. Figure
12 illustrates the water seal. Note that water is “pulled”
up toward the condensate collector pan and is pushed
down slightly by the vent/blower drain. If there is no water
seal, air rushes into the collector drain, preventing normal
drainage of condensate water, until vent drainage provides
the seal. See Section 2.12, Start-Up and Adjustment.
The installer must be sure to take whatever measures
are necessary to prevent property damage by condensate
overflow. If the heater location is such that this water
can directly or indirectly damage a building, furnishings
or other property, an overflow pan or other appropriate
preventative measure should be provided.

Jandy® Pro Series, Hi-E2® and Hi-E2®R Gas-Fired Heater | Installation & Operation Manual
Support gas piping properly so its weight does not bear on
the heater. Install a drip leg, a non-restrictive shutoff valve
and a union on the gas supply line outside of the heater.
See Figure 13.
Before operating the heater, test the gas supply system,
including all connections, for leaks using a soap solution.
Do not use a flame or any ignition
source for leak detection. Disconnect the heater and its
individual gas shutoff valve during pressure testing if
the test pressure is higher than 1/2 psig (3.34 kPa). If the
pressure is 1/2 psig (3.45 kPa) or lower, close the manual
valve on the heater gas control during testing.
ATTACH GROUNDING WIRE TO
GREEN GROUNDING SCREW
(115 VAC ONLY)
When the heater is started, check the supply pressure
to verify that it is adequate during heater operation.
Undersize piping, a restrictive fitting or an undersize gas
meter can cause low operating pressure.
High Elevation
To assure good combustion and general operation, gas
appliances are normally de-rated when installed at high
elevation. This is not necessary with the Hi-E2 because it
has a special venturi-type combustion system which selfcompensates for changes in barometric pressure. Air flow
through the venturi pulls the correct flow of gas into the
burner regardless of air density. Good quality combustion
and high efficiency are assured without special adjustment
or changes to the heater.
2.9.1 Special Precautions for LP Gas
LP Gas is heavier than air and can therefore more readily
collect or “pool” in enclosed areas if provision for proper
ventilation is not made. Installation of pool heaters in
enclosed areas such as pits is not recommended. However,
if such an installation is required be sure to pay special
attention to proper ventilation requirements for LP gas.
Locate heaters a safe distance from LP gas cylinders and
filling equipment. Consult the National Fuel Gas Code
(NFPA 54 / ANSI Z223.1, latest edition), the Natural
Gas and Propane Installation Code in Canada (CAN/
CSA B149.1, latest edition), and any other local codes
and fire protection authorities about specific installation
restrictions in your area.

2.10.1.Electrical Power
Electrical wiring must be in accordance with the latest
edition of the National Electric Code (NEC), ANSI/
National Fire Protection Association (NFPA) 70, unless
local code requirements indicate otherwise; and in Canada
with latest edition of CSA C22.1 Canadian Electrical
Code.
The Hi-E2 requires electrical power from a 115V, 60 Hz
source. Do not connect this heater to a 230VAC power
source. Wiring connections must be made exactly as
shown in the wiring diagram, see Figure 15. Grounding
must be provided as required by the prevailing electrical
code.
Connect wiring inside the junction box, which is on the
right side of the heater and is accessible through the door
opening. Line voltage connections must be made within
this box. A labeled green grounding screw is provided in
the junction box for a grounding wire. See Figure 14.
Wiring should include a means to prevent operation of
the heater when there is no water flow. This is typically
done with a time clock “Fireman’s Switch” as discussed in
Section 2.10.3.

Zodiac® requires that the appliance be connected to a
"bonding loop" that includes all electrical equipment in
the system and on the equipment pad. Bonding lugs must
be connected with a solid copper wire not smaller than
8 AWG (6 AWG in Canada). Failure to do so will void
warranty.
Additionally, in the United States the National Electrical
Code and in Canada the Canadian Electrical Code, require
that all metallic components of a pool structure, including
reinforcing steel, metal fittings and above ground
components be bonded together (forming a “bonding
grid”) with a solid copper conductor not smaller than a 8
AWG (6 AWG in Canada).

The NEC and the CEC also require that the equipment
and/or appliances associated with the pool water
circulating system, including, but not limited to, pump
motors and heaters be bonded together as part of the
equipotential bonding grid. Zodiac® provides a special
labeled bonding lug on the right side of the heater to
accommodate this requirement.
2.10.3 Auxiliary Time Clock Wiring
If a time clock is provided to control the pool filter pump,
it should have a separate low-voltage (Fireman’s) switch
for the heater. Route the heater’s 24 VAC control circuit
through this switch as shown in Figures 16 and 17. To do
this, remove the “jumper” from the terminal block in the
heater control compartment. Connect two (2) wires to this
terminal block and route them to the Fireman’s switch at
the time clock. Provide wiring of at least 18 gauge with
insulation at least 3/64" thick and having a temperature
rating of at least 90°C.
2.10.4 Remote Operation
The Hi-E2 pool/spa heater controls can be wired for
remote operation. The Jandy Pro Series AquaLink® RS
remote control permits switching from pool to spa, with
temperature set points for each, and turning the heater on
and off from a remote location. Contact your local Jandy
Pro Series distributor for information on the AquaLink®
RS control system to fit your back yard recreational needs.
Figure 18. Water connection as shipped.
Figure 19. Water connection reversal.
An interrupt (on/off) type remote can be connected by
removing the jumper wire on the terminal block located
in the control compartment, see Figure 17 and connecting
the two (2) wires from the remote to the two (2) terminals
on the terminal block. This type of remote control will
turn the heater on or off, but will not switch between the
two (2) temperature controllers on the temperature control
panel or allow for temperature adjustments.
To connect a 3-position remote switch (not supplied by
Zodiac®) to a Hi-E2 heater, order a wire harness assembly
(Zodiac part No. E0120000) which connects to the
temperature control panel. Installation instructions are
included with the wire harness assem-bly. This type of
remote will allow switching between the "POOL", "SPA",
and "OFF" function of the control but does not allow for
temperature adjustments.
2.11 Water Piping
2.11.1 Reversal of Water Connections
The Hi-E2 is shipped with water connections on the right
side, but it can be modified in the field to provide leftside water connections. This is done by removing the
water headers and re-installing them opposite to their
original location. Some of the heater wiring and control
components must be relocated, so this change must be
done only by a trained service technician.

the retainer bracket and screw.
11.
Re-install the pressure switch tube and fitting.
Relocate fitting.
12. Adjust wiring and pressure switch tube routing
so that they don't rest on sharp edges or on
the hot surfaces of the combustion chamber.
The combustion chamber is the portion of the
assembly just above the heat headers.
13. Re-assemble all other components and fasteners.
2.11.2 Pool/Spa Piping Systems
Figure 20 illustrates typical piping for pool equipment
in pool/spa combination pools. With its Flex-Temp
temperature control, the Hi-E2 is particularly suitable for
this type of pool installation.
The heater must be protected from back-siphoning of
water, which can result in dry starts. If there is any chance
of back-siphoning, provide a check valve between the
pool and the filter pump inlet.
Arrangement of pool system components other than as
illustrated in these diagrams can affect the operation of
the heater’s water pressure switch. Location of the heater
above or below the pool water surface can also affect
operation of the switch. In general, the pressure switch
can be adjusted to accommodate this effect if the heater

2.11.3 Connections at Heater
The Hi-E2 has a universal water header and flange design.
With this feature, a variety of piping materials and sizes

can be connected directly to the heater using the rubber
“donut” gaskets provided with the heater. 2" PVC or metal
pipe can be threaded directly to the flanges and 1-1/2"

A pressure relief valve is mandatory in any installation in
which the water flow can be shut off between the heater

A pressure relief valve is not supplied with the Hi-E2 in
the United States; however, it may be required by local
codes. A pressure relief valve must be provided in Canada.

water connections are no more than six feet below the
pool water surface and no more than 15 feet above it. See
instructions for pressure switch adjustment in the heater
start-up section of this manual for more information about
this. Note that when pool equipment is located below the
pool surface a leak can result in large scale water loss or
flooding. Zodiac cannot be responsible for such water loss
or flooding or the damage caused by it.
Do not install a shutoff valve or any kind of variable
restriction in the water piping between the heater outlet
and the pool/spa.
Pool systems with water flow rates higher than 100 GPM
require an adjustable external bypass at the heater. See the
section on start-up and adjustment for this information.
To install a pressure relief valve, remove the 3/4" brass
plug from the top of the inlet/outlet header, see Figure 22.
Install the pressure relief valve in the opening. Provide a
short length of brass or stainless steel pipe as necessary to
position the valve above the sheet metal cover. Turn the
valve or route discharge piping as necessary to assure that
hot steam will not endanger persons near the heater. The
valve setting should be at or below the maximum working
pressure of any component in the filter system. The
working pressure of the Hi-E2 heater is 75 psig.
Some local codes may also require installation of a
temperature relief valve. Check with your local codes for
requirements in your area. The valve setting should be in
accordance with local codes. Zodiac® recommends that
the water delivered to the pool not exceed 104°F. All
temperature and/or pressure relief valves must be listed
by a Nationally Recognized Testing Lab (NRTL) such as
CSA, UL, or ETL.
2.11.5 Automatic Chlorinators (Chemical Feeders)
A high concentration of chlorine (and many similar
chemicals) in the pool heater can be very destructive.
Heater damage caused by chemical concentration is not
covered by the Warranty. See Table 7 for guidelines on
pool water chemistry.
IMPORTANT
If an automatic chlorinator is being used,
equip the chlorinator with an anti-siphoning device so
that chlorine will not siphon into the heater after the
pump shuts off.
Out
Water In
Figure 22. Pressure relief valve installation.
Wire an electric chlorinator so that it cannot operate unless the
filter pump is running. If the chlorinator has an independent
clock control, synchronize it with the filter clock.
If the chlorinator is equipped with its own pump, install
it so that it introduces the chlorine downstream from the
heater, and, if possible, below the level of the heater outlet
fitting.
Jandy® Pro Series, Hi-E2® and Hi-E2®R Gas-Fired Heater | Installation & Operation Manual
2.12 Start-up and Adjustment
2.12.1 Normal Operation
The Hi-E2 pool heater operates automatically. It provides
heat in response to the selector switch and temperature
settings on the control panel on the front of the heater. The
heater has internal controls to sense adequate water flow
and to handle any abnormal condition.
Normal operation is as follows:
1.
The pool/spa system filter pump provides water
flow. A pressure-flow switch in the heater detects
water flow and enables the control to operate the
heater. (If the recommended fireman switch has
been provided, it must also enable operation.)
2.
If the selector switch is set to "Pool" or "Spa", and
if the water temperature is not warm enough, the
control signals the combustion system to start.
3.
The ignition control starts the combustion blower.
4.
When the venturi pressure switch detects
combustion air flow and when a suitable “prepurge” time has been allowed, the ignition control
energizes a “hot surface” igniter.
5.
The igniter is allowed to reach ignition temperature,
at which it glows bright red-orange. This is visible
through the combustion chamber view port.
6.
The gas valve is opened and gas flows into the
combustion air. The gas/air mixture flows through
the burner into the combustion chamber. It is
ignited by the igniter.
7.
The ignition control electronically senses
successful ignition by “flame rectification”, and
the gas valve is allowed to stay on. The igniter is
de-energized.
8.
The heater operates for as long as the control
demands heat, subject to continued water flow
and satisfactory operation of the system.
9.
When the control stops calling for heat, the
ignition control shuts off the gas valve and the
flame goes out.
10. The ignition control continues to operate the
combustion blower for a “post-purge” period,
after which it is turned off.
The process is repeated upon the next call for heat. If ignition
is unsuccessful, or if the flame fails during normal operation,
the ignition shuts off the gas valve. It imposes a post purge
and two (2) more ignition cycles, and it shuts down the
system if ignition is not achieved in three (3) cycles.
ENGLISH
Page 17
system and equipment. Start the heater in accordance
with the Operating Instructions section of this manual,
with particular attention to the lighting and shutdown
instructions and temperature control operation.
The heater may not start on the first try. Air in the gas line
or other start-up situations may cause it to recycle. It will
lock out if ignition is not achieved in three attempts. To
provide three (3) additional attempts, turn the pool/spa
selector switch off and then back on.
When the heater starts, immediately feel the outlet header
of the heater to confirm that there is adequate water
flow. The header should not be hot. Normally, water
temperature will rise only a few degrees as it passes
through the heater, and a “hot” header or pipe indicates
low water flow.
WARNING
When the heater is fired for the first time, the
combustion chamber refractory binder material is
driven out by the heat of the flame. White smoke and/
or sharp odors may be emitted from the vent during
this period. Do not inhale combustion product fumes
at any time, and especially when these fumes are
being emitted. This “burn-in” period will last only a few
minutes.
AVERTISSEMENT
Lorsque l’appareil est mis en marche pour la première
fois, le matériau liant réfractaire de la chambre de
combustion est expulsé par la chaleur de la flamme.
De la fumée blanche et de fortes odeurs peuvent se
dégager du tuyau d’aération à ce moment-là. N’inhalez
les fumées de combustion à aucun moment, surtout
au moment où elles sont émises. Cette période de
combustion ne durera que quelques minutes.
2.12.3Condensate
If there is no water in the condensate trap, the heater’s
combustion blower will pull air into the lower drain hose
and normal drainage of combustion condensate will not
occur. This water will accumulate to blower inlet level and
will (temporarily) be blown out of the vent. Eventually it
will drain back to the tray and will "prime" the trap. To

avoid this "wet" start-up, simply pour water into the tray
before starting the heater, as indicated earlier reach the
blower and will (temporarily) be blown into the vent and
may be thrown into the air around the heater.
2.12.4 Gas Pressure
Confirm that gas supply is of adequate size per Section
2.9 of this manual. Confirm that the step-down regulator
is properly set by verifying that the pressure at the port on
the inlet side of the gas valve is 1.25 - 3.0 WC with the
heater operating.
Checking of gas pressure at the outlet of the gas valve
requires knowledge of the venturi system of the Hi-E2
pool heater. Do not attempt to adjust this pressure without
thorough understanding of its operation and settings, as
outlined in the maintenance section of this manual.
2.12.4.1 Step-down Gas Pressure Regulator
Model Hi-E2 pool heaters include a step-down regulator to
reduce the pressure of gas entering the combination gas valve.
This regulator is factory set between 1.25” and 3.0” WC
regardless of whether natural or LP gas is used by the heater.
The step-down regulator does not change requirements
for gas supply piping or pressure, and it does not change
servicing procedures for the venturi/combination flow
system. Gas supply must be as stated in the installation
and operation manual and on the heater rating plate.
Servicing procedures for the venturi/combustion
flow system must be as specified in the installation
and operation manual. Incorrect adjustment of the
combination gas control can cause improper heater
operation and hazardous combustion emissions.
If it is necessary to verify adjustment of the step-down
regulator, its outlet pressure can be measured at the inlet
tap of the combination gas valve, which is immediately to
the right of the step-down regulator.
To order this regulator as a separate part, please order kit
number R0337300, shown in Figure 23.
2.12.5 Adjustment of Water Pressure Switch
The pressure switch is pre-set at the factory for normal
pool installations. Do not adjust it unless the heater water
connections are more than three feet above or below the
pool surface. If they are not in this range, the pressure
switch must be adjusted. This can be done in the field if
the water connections are no more than six feet above the
pool surface and no more than ten feet below it. For other
situations, contact a Jandy Pro Series representative.
CAUTION
The water pressure switch should be adjusted to turn
the heater off when the pump is off. Setting the switch
to close at too low of a flow can damage the appliance.
Adjust the switch to turn the heater off, not on.
ATTENTION
Le régulateur de pression de l’eau doit être réglé de
manière à fermer le réchauffeur lorsque la pompe
s’arrête. Le réglage de fermeture du régulateur à un
débit trop faible peut endommager l’appareil. Régler le
régulateur pour éteindre le réchauffeur, non pour l’allumer.
To adjust the pressure switch, proceed as follows. See
Figure 24.
The pool filter must be clean before making this
adjustment. The heater does not have to be firing.
1.
Turn the switch to OFF, and make sure the
pressure switch is at its lowest setting. This is
done by rotating the adjuster counterclockwise as
far as it will go.
2.
Start the filter pump and confirm by means of
an ohmmeter that the pressure switch closes (if
the switch fails to close, replace it with a switch
which has a lower minimum setting).
3.
Turn switch to ON. Heater should start.
4.
With your fingers, turn the adjustment sprocket
very slowly clockwise until the heater goes off.
5.
Slowly turn the pressure switch adjustment
sprocket counterclockwise one-quarter turn. The
heater should come back on.
6.
Check the adjustment by turning the filter pump
OFF. The burners should shut off immediately.
If they do not, restart the filter pump and repeat
Steps 6 and 7. Check the adjustment again.
7.
SLOWLY TURN ADJUSTMENT
SPROCKET CLOCKWISE
UNTIL HEATER GOES OFF.
Return the pool temperature control to the desired
temperature.
It may be necessary to repeat these steps to get a proper
setting. The switch must be set so that the heater will not
fire unless the pump is running. If a proper setting cannot
be reached, contact the factory service department.

If the piping system has a manual bypass valve,
gradually open it until the temperature rise is in
the range required by Table 6.
6.
Scribe a line on the bypass valve shaft and case
to mark the correct adjustment position. Wire the
handle to the pipe to prevent tampering.
Note that temperature rise is somewhat less when the
water is hot (spa application) and when heater is installed
at elevations significantly above sea level. For high
elevation installations, reduce the numbers in Table 6 by
3% per 1000 feet above sea level.
Table 6.
Figure 25. Temperature rise measurement at return
header.
2.12.6 Water Temperature Rise
The Hi-E2 pool heater has an internal bypass device which
accommodates a wide range of water flow. Its purpose
is to assure that flow through the heat exchanger is
adequate to provide high efficiency operation and prevent
overheating even though flow through the filter system
may vary.
Correct water flow should be confirmed upon start-up of
the heater and in most servicing situations. If flow is not
normal, corrections must be made to the pool system. If
the system has an external flow bypass (because of very
high filter system flow), it should be adjusted to provide
proper flow through the heater. Flow is evaluated by
determining the water temperature rise through the heat
exchanger.
Before checking temperature rise, be sure the pool filter
is clean. If necessary, clean the filter. Temperature rise
is measured at the return header, which is on the side
opposite to the inlet/outlet header. For access, remove the
side cover, which is held in place by wing nut fasteners
inside the heater. Remove the brass plug on the top
surface of the header and install a Pete's Plug and pocket
thermometer. See Figure 25.
Proceed as follows:
1.
If the piping system has a manual bypass valve,
close it.
2.
Turn off the heater by moving the switch on the
temperature control panel to “Off”.
3.
After three minutes, note and record the
thermometer reading. This is the pool
temperature.
4.
Start the heater and let it operate for at least
five minutes. Note and record the thermometer
reading. The difference between this reading and
the first one is the temperature rise.

In a system without external bypass, it may be necessary
to make changes. If temperature rise is too low, a manual
bypass must be installed. If temperature rise is too high,
there is inadequate flow, possibly requiring a change to
the piping system or a larger pump. Before proceeding
with either remedy, verify proper heater operation. Low
gas input results in low temperature rise and vice-versa.
A problem with the heater internal bypass assembly also
affects measured temperature rise.
Section 3. Operating Instructions
Lighting and shutdown instructions are posted inside the
heater.
WARNING
LP GAS: To avoid possible injury, fire and explosion,
read and follow these precautions and all instructions
on this appliance before starting the heater. LP
(propane) gas is heavier than air and will remain at
ground level if there is a leak. Before lighting, sniff at
ground level. If you smell gas, follow these rules:
1. DO NOT light matches. DO NOT turn electric
lights or switches on or off in area. DO NOT use
an electric fan to remove the gas from area.
2. Shut off gas at LP tank.
3. Telephone gas company and fire department for
instructions. Give your name, address and phone
number.
If your LP tank runs out of fuel, turn off gas at the
appliance. After the tank is refilled, the appliance must
be re-started according to the instructions located on
the inside of the door.

With any new pool or spa installation, run the filter pump
with the heater off long enough to completely clean the
water. This removes any installation residue from the
water. Clean the filter at the end of this operation before
starting the heater. Do not operate the heater unless the
pool is properly filled with water.
When raising the temperature of water in a cold pool,
remove all time clock settings. This lets the filter system
and heater operate continuously until the water reaches the
temperature setting on the thermostat. When that happens,
the heater will shut off automatically, but the filter pump
will keep running.
3.2
Temperature Controls
The Hi-E2 heater has a dual temperature control which
allows either of two (2) different temperature settings to
be selected with the rotary switch on the control panel.
The owner can set one control for normal use and the
other for standby, or one might be set for a pool and the
other for a spa. Setting the rotary switch to the middle
position turns the heater off. See Figure 26.

Water Chemistry
3.4.1Pools
3.3.1 Lighting the Heater
1.
3.3.2Shutdown
The mineral content of swimming pool water increases
daily, due to natural evaporation and the addition of
sanitizing chemicals. If the mineral concentration in the
pool gets too high, the excess minerals will deposit on the
walls of the pool, in the filter system, and in the heater
tubes. It is important to keep the pH factor of the pool
water between 7.4 and 7.6. See Table 7 for guidelines on
other chemical measurements.
3.4.2Spas
The proper chemical balance in spa water is more critical
than in a swimming pool heater operation. Due to the spa's
size, high water temperature, and heavy usage, chemical
values in a spa can vary greatly. This chemical imbalance
can result in unsanitary water conditions, and affect the
life of the heater.
3.4.2.1 Spa Water Chemistry
Maintaining safe water conditions in a spa can only be
done by regular water changes and the proper addition of
sanitizing chemicals. Kits are available from your local
pool supply dealer for making the various tests for mineral
content. One of these kits will detect copper in the system.
This is usually a warning that corrosion is taking place,
possibly due to a low pH value combined with other
chemistry problems. The condition can be corrected by
changing the spa water and closely monitoring the pH
factor and chemical properties of the water. See Table 7.

3.4.2.2 Water Changing
Zodiac Pool Systems, Inc. recommends changing of
spa water every 60 days if usage is light and every 30
days during heavy usage. Be sure to stabilize the water
chemistry after every water change.
3.4.2.3Corrosion
The corrosive action of pool/spa water is increased by the
following:
6.
Persons taking medications which induce
drowsiness, such as tranquilizers, antihistamines,
or anticoagulants should not use spas or hot tubs.
Prolonged immersion in hot water can induce
hyperthermia. Hyperthermia occurs when the internal
body temperature reaches a level several degrees above
the normal body temperature of 98.6°F (37°C). Symptoms
include dizziness, fainting, drowsiness, lethargy, and an
increase in the internal body temperature.
The effects of hyperthermia include:
1.
Low pH - acidity
• Unawareness of impending hazard
2.
Low Total Alkalinity - bicarbonates
3.
Low Calcium hardness - soft water
• Failure to perceive heat
NOTEZodiac does not warrant heat exchangers damaged
®
by corrosive water.
3.4.2.4Testing
Zodiac recommends that spa owners purchase a test kit
and use it regularly. A minimum kit is one which will
measure chlorine and pH levels.
The pool/spa owner will find it helpful to have a qualified
professional technician perform more extensive chemical
testing and water changing on a regular basis.
3.5
• Failure to recognize need to leave spa
• Physical inability to leave spa
• Fetal damage in pregnant women
• Unconsciousness resulting in a danger of drowning
3.6
Zodiac suggests the following to help conserve fuel and
minimize the cost of operating your pool heater without
sacrificing comfort.
1.
Set the heater temperature control no higher
than 78°F (26°C). The American Red Cross
maintains that the healthiest water temperature
for swimming is 78°F (26°C). Be certain you are
using an accurate pool thermometer because a
variance of 4°, from 78 to 82°F (26 to 28°C), will
use as much as 40% more gas.
2.
Carefully monitor the water temperature of your
pool in the summer time, because heater usage
can be reduced due to warmer air temperatures.
3.
Find the proper setting on the pool heater
temperature control and use the TEMP-LOK to
discourage further adjustments.
4.
Set the filter time clock to start the pump no
earlier than 6:00 AM during the pool heating
season. This is the time when nightly heat loss
stabilizes.
Spa/Hot Tub Safety Rules
The following "Safety Rules for Hot Tubs," recommended
by the U.S. Consumer Product Safety Commission should
be observed when using the spa:
1.
2.
3.
Spa or hot tub water temperature should never
exceed 104°F (40°C). A temperature of 100°F
(38°C) is considered safe for a healthy adult.
Special caution is suggested for young children.
Drinking of alcoholic beverages before or during
spa or hot tub use can cause drowsiness which
could lead to unconsciousness and subsequently
result in drowning.
Pregnant women beware! Soaking in water above
102°F (39°C) can cause fetal damage during the
Swimming Pool Energy Savings Tips

5.
If the pool is only going to be used on weekends,
reduce the heater temperature control setting by 8
or 10 degrees during the week. It should be reset
to the 78°F (26°C) level before expected usage,
keeping in mind to allow enough lead time for the
water to reach the desired temperature.
6.
During the winter shut down the heater by
following the lighting and shutdown instructions
in Section 3.1. When on vacation for longer than
a week, make sure the heater is shut off at the
temperature control panel.
7.
Where possible, shelter the pool from prevailing
winds with well-trimmed hedges or other
landscaping, cabanas, or fencing.
8.
Always use a pool cover when practical. Besides
providing a valuable safety feature, a pool cover
will reduce heat loss, conserve chemicals, and
reduce the load on filter systems.
3.7
Seasonal Care
3.7.1 Spring and Fall Operation
During periods when the pool is only going to be used
once in a while, turn the temperature control to the "MIN"
setting. This prevents the pool from becoming "chilled,"
yet still requires the least amount of time to raise the water
back up to swimming temperature.
If the heater is not going to be used for a long period of
time, shut it down completely, following the instructions
in Section 3.3.2, Shutdown, or the lighting and shutdown
instructions posted inside the heater.
3.7.2Winterizing
If you don't plan to use the pool or spa over the winter
and your area is subject to freezing temperatures, have a
qualified professional technician perform the following
steps to protect the heater:
1.
Shut off the heater's gas valve according to the
lighting and shutdown instructions.
2.
Shut off the main supply gas cock outside the
heater jacket.
3.
Completely drain the heater before the first frost.
To drain the heater, remove the side panel, and
remove the drain plug. See Figure 28.
4.
Grease the threads of the drain plug and return it
to the manifold, but do not tighten.
5.
Disconnect the copper tubing from the pressure
switch fitting. See Figure 28.
6.
Cover the vent grille so that snow will not
accumulate in the combustion blower, where it
may freeze.

Induced-Draft Combustion System
The Hi-E2 pool heater has an advanced combustion
system which makes it highly efficient and reliable. This
system is illustrated in Figure 30.
A special corrosion resistant high-speed blower pulls
flow through the system and exhausts it to the outdoors.
Air is pulled into the system through a combustion air
supply duct, when provided, and through an air filter into
a venturi. The venturi functions much like an automobile
carburetor venturi - i.e. when air is forced through it, a
“negative” pressure is created at the venturi throat. This
negative pressure pulls gas through a metering orifice,
resulting in an optimal mixture of air and fuel gas. The air
and gas are thoroughly mixed in the venturi tailpipe, pulled
through a special burner and ignited in the combustion
chamber. Hot combustion products are then pulled
through a highly efficient downward-flow heat exchanger.
Combustion products are cooled below their dew point and
condensate water is formed and drained away. Flow then
enters the blower, where it is forced out of the heater at the
vent terminal or through a vent pipe to the outdoors.

Heater Components and Their
Operation
Gas valve / Regulator - The gas valve controls
gas flow into the venturi. It provides flow only
when the temperature control require heat and
only if all safety controls enable operation. It is
also a negative pressure regulator. It regulates the
gas pressure to 0.2” WC less than the air pressure
at the venturi inlet. This is necessary for proper
operation of the venturi system and cannot be
done with common (positive pressure) gas valves.
2.
Combustion blower - The combustion blower is
a specially designed to handle moist combustion
products, having special plastic housing and
impeller. It is powered by a brushless DC motor.
3.
Temperature Control - The control is an electronic
control which senses water temperature by means
of a thermistor and controls heater operation to
bring the water to that selected. It has two (2)
temperature setting knobs which are typically
used to set pool and spa temperatures. A selector
switch determines which setting is chosen.
4.
Ignition Control - The ignition control provides
energy for ignition of the air/gas mixture,
monitors the flame and controls the combustion
blower and gas valve. When the temperature
control requires heat, the ignition control
starts the blower, providing a pre-purge of the
combustion chamber. Then it applies electrical
power to a “hot surface” igniter. When the igniter
is hot enough, it opens the gas valve. It has
sophisticated means to sense ignition and flame
condition so that unburned gas will not escape.
After the burner is shut off, it continues blower
operation to provide a post-purge period.
5.
Igniter - The hot surface igniter is a ceramic
element which becomes very hot when electrical
power is applied to it. It functions both as an
igniter and as flame sensor. As a sensor, it is the
electrode through which the ignition control
detects “rectification” of current passed through
the flame. Inadequate rectification indicates an
unsatisfactory flame condition. The ignition
control responds to the flame signal provided by
the ignitor.
6.
Venturi Pressure Switch - This switch verifies
that air is flowing through the combustion system
by sensing pressure reduction at the venturi throat
(relative to pressure at the venturi inlet). It shuts
off the heater if air flow is inadequate.
7.
Limit Switches - Two (2) limit switches prevent
excessive water temperature - one (1) within the
heat exchanger and one (1) for water leaving the
heater. If either senses excessive temperature,
burner operation is interrupted.
8.
Water Pressure Switch - This control senses whether
or not water is available to the heater by measuring
back pressure inside of the heat exchanger. If the
pool water pump fails or the water filter is blocked,
the pressure switch prevents operation of the burner.
It can be affected by the installation conditions as
discussed earlier in this manual.
9.
Burner Temperature Limit Switch - This is a
single-use switch which detects abnormal burner
temperature. It is a disc-type switch which is
held against the burner plenum by a sheet metal
bracket. It has the appearance of an automaticreset switch in that it has no reset button.
However, it will reset only if cooled to -31°F, and
therefore will not recycle. The burner limit switch
prevents or interrupts burner operation if the
burner plenum becomes too hot.
10. Vent Limit Switch - The vent limit switch
protects the vent system from excessive exhaust
temperature. It is located on the vent diffuser
above the combustion blower. It interrupts burner
operation if temperature becomes too hot for the
plastic materials used to vent the heater.
See the earlier section entitled Start-up and Adjustment
for the normal sequence of operation.

Combustion Air Filter
WARNING
To avoid the risk of exposure to unsafe levels of
Carbon Monoxide, which can result in serious personal
injury or death, always ensure that the combustion
air filter is properly installed and secured in the tracks
provided in the air filter box.
AVERTISSEMENT
Pour éviter le risque d’exposition à des niveaux dangereux
de monoxyde de carbone qui peuvent provoquer des
blessures graves ou la mort, s’assurer toujours que le
filtre à air secondaire est correctement installé et fixé
solidement dans les rainures prévues du filtre à air.
Filter
Figure 31. Air filter replacement.
Jandy® Pro Series, Hi-E2® and Hi-E2®R Gas-Fired Heater | Installation & Operation Manual
The combustion air filter is a rectangular foam
filter located in a box near the bottom of the control
compartment. The filter removes lint and large scale dust
particles to prevent blockage of the burner media.
The filter should be replaced annually in normal
service. Heavy use of the heater or operation in adverse
environments may dictate more frequent replacement,
however. It can be removed through the front of the filter
box as illustrated in Figure 31.
Remove the wing nuts retaining the front panel and slide
the panel out. Replace it only with the specified part
available from a Jandy Pro Series representative. Push the
replacement filter into the tracks and slide the panel back in.

tous les fils avant de les débrancher. Des erreurs
de câblage peuvent entraîner un fonctionnement
inadéquat et dangereux.
This section describes procedures for checking the
electrical power and control components of the heater
one at a time and in the order they appear in the control
circuit.
These procedures require a Volt-Ohm meter with 0-150
VAC range, and 0-1000 Ohm resistance range. Figure 32
shows the power and control circuits, and where to take
measurements. Location numbers in circles have been
added, and will be referenced in the following sections.
As stated at the beginning of this manual, some of these
procedures are hazardous. Only a qualified service
technician should service the heater.
4.5.1 115V Electrical Power Supply
The electrical components of the Hi-E2 pool heater are
designed to operate with supply voltage ranging from
103V to 126V at 60 Hz. Measure supply voltage at the
“hot” and “neutral” wirenut connections in the heater
electrical junction box (identified as points A and B on
the wiring diagram). If no voltage is present, correct
this external to the heater. Circuit breakers, time clock
settings or similar devices may be the problem. Voltage
outside of the above range may be due to poor wiring,
poor connections, other loads such as air conditioning
compressors or to an electric utility company problem.
Arrange for correction of the voltage as appropriate.
4.5.2 Control Circuit Trouble Shooting
The heater controls are in a 24V 60 Hz circuit with
operating and safety controls basically arranged in a
series circuit. Trouble shooting is done by probing for
voltage at various points in the circuit to determine which
component is preventing operation. Check points are
indicated on Figure 32. The recommended procedure
steps through the circuit in a sequential way, but verifying
voltage at any of the numbered points confirms that all
prior components are OK. Experienced technicians may
be able to shorten the process by going directly to one of
the intermediate test points.
4.5.2.1Transformer
Attach one lead of the voltmeter to the transformer
terminal with a yellow wire attached to it, which is point
11 on Figure 32. (This lead can be left in place for most
of the testing.) Touch the free lead of the meter to the
transformer terminal with a red wire, point 1. The meter
should show 20-28 volts. If there is no voltage, replace the
transformer.
4.5.2.2Fuse
Leaving the “common” voltmeter lead in place at point
11, touch the free probe to point 2. This is the terminal
block screw attached to the red wire from the in-line fuse,
and absence of voltage indicates a defective fuse. If there
is no voltage, inspect the rest of the wiring to be sure
that there is no “short” such as contact of a terminal with
the heater chassis or another terminal. Correct any such
condition and replace the fuse.
4.5.2.3 Fireman Switch and External
Interlocks
Probe for voltage at point 3, the other connection of the
terminal block, which has a white wire connected to
it. If there is no voltage, the time clock switch or other
external interlock may be mis-adjusted, mis-connected or
defective. Correct this external problem.
4.5.2.4 Limit Switches
Probe for voltage at point 4, which is the water pressure
switch terminal with the white wire connected to it. This
switch is mounted on the end of a copper tube and is
about 2” in diameter. Absence of voltage at this point
indicates that one of the limit switches is open. This is
normally due to excessive water temperature, which should
be thoroughly investigated before replacement of limit
switches. Water flow deficiency may be due to obvious
problems such as a defective pump or blocked water filter.
Alternatively, it may be due to overfiring, or to a problem
with the water piping or the heater's internal bypass control.
Overfiring might be a result of an incorrect gas orifice or
supply of propane gas to a heater intended for natural gas.
If there are no such fundamental problems, identify which
of the switches is open by temporarily connecting a jumper
wire across its terminals. Replace a defective limit switch.
Limit switch access is through the side cover panel on the
side of the heater to which water pipes are connected.
NOTE The limit switches have different trip points, and it is
important that replacements are correct. The 150°F
switch has a red dot on the side of the brass fitting, and
must be installed closest to the combustion chamber.
The 135°F switch has no dot and must be installed in
the tapping closest to the water piping connections.
4.5.2.5 Water Pressure Switch
Touch the voltage probe to point 5, which is the other
terminal of the water pressure switch having a black wire
is connected to it.
If there is no voltage, the pressure switch contacts are
open. This is almost always due to a water flow deficiency,
the most common one being a blocked water filter. It may
be due to causes cited in the previous paragraph, however,
and sometimes is due to blockage of the copper tube or
mis-adjustment of the switch. Investigate thoroughly,
referring to the earlier section on “Adjustment of Pressure
Switch”. If there is no problem with the pool system or
pressure switch adjustment, replace the pressure switch.
Jandy® Pro Series, Hi-E2® and Hi-E2®R Gas-Fired Heater | Installation & Operation Manual
4.5.2.6 Temperature Control
Probe for voltage at point 6, which is the terminal of the
venturi pressure switch having a yellow & black wire
connected to it. This is the switch mounted on the frame
above the blower between the vent diffuser and the
venturi tailpipe. It is about 4” in diameter.
Absence of voltage at point 6 indicates that the control is
not calling for heat. Be sure that knobs are set to call for
heat as indicated earlier and as described in the Operating
Instructions section of this manual. Verify that the
thermistor sensor wires are not severed or shorted. Check
wiring connections by removing the temperature control
through the front of the bezel. If the control is properly
set and all wiring and connections are correct, replace the
control.
4.5.2.7 Venturi Pressure Switch
Touch the voltmeter probe to point 7, which is the
terminal of the venturi pressure switch having a purple
wire connected to it. If there is no voltage at point 7, the
venturi pressure switch is open, indicating inadequate
flow through the combustion system. The venturi pressure
switch is a differential type switch which is activated by
the pressure difference created when air flows through the
venturi. When the combustion blower is not operating,
the venturi pressure switch must be open and voltage will
not be present. See following sections on ignition control
"lockout" and combustion blower operation for possible
remedies.
Check for blockage at the combustion air inlet, a dirty
air filter or blockage at the vent exhaust or in the vent. In
improperly installed vent may trap condensate water, for
example, restricting flow. If there is no obvious problem,
analyze venturi operation as outlined in a later section of
this manual. If flow is normal, replace the venturi pressure
switch.
4.5.2.8 Ignition Control
There will be voltage at point 8, which is the “MVP”
terminal of the ignition control, only when there is an
attempt to ignite the burner or when the ignition control’s
flame sensing system has determined that it is OK to allow
burner operation. Even if voltage has been confirmed at
point 7, the “trial for ignition” sequence is imposed by the
ignition control. This sequence consists of a 15 second
period of pre-purge blower operation, a 40 second period
for heatup of the igniter and a 7 second trial for ignition,
during which there is voltage at point 8. If satisfactory
ignition is not achieved, the igniter is turned off and the
blower is operated for a 45 second post-purge. The system
may go through this cycle as many as three (3) times,
but thereafter it is “locked out” by the ignition control.
Additional attempts will be made only if the call for heat
is interrupted by turning off electrical power or setting the
control to “Off”.
ENGLISH
Page 29
To trouble shoot the ignition control, connect the voltmeter
probe at point 8 and set the control to call for heat. Observe
that the normal sequence takes place by noting blower
operation, the glow of the igniter through the combustion
chamber sight glass and then voltage at point 8. If the
blower does not operate or the igniter doesn’t glow,
investigate as outlined in a later sections. If both of these
components operate normally but voltage doesn’t appear
at point 8 during the trial for ignition, replace the ignition
control. If voltage appears at point 8 but there is no
ignition, proceed to analysis of other components.
4.5.2.9 Burner Limit Switch
The burner limit switch is located on the front surface of
the burner plenum near the top of the heater. Servicing this
switch normally requires removal of the top of the heater,
but it can be checked by probing for voltage at point 9 on
the vent limit switch. Point 9 is the terminal of the vent
limit switch to which is connected a brown wire coming
down from above. The vent limit switch is mounted on the
vent outlet diffuser above the combustion blower.
Voltage will be present at point 9 only during normal
operation or during a trial for ignition. If necessary
restart the heater using the control to obtain one of these
conditions. If voltage does not appear at point 9, the
burner limit switch is open. This may be due to burner
mis-adjustment, incorrect gas orifice size or similar
problems which should be investigated as outlined in
later sections. If there are no such problems and there is
no evidence of excessive burner temperature, replace the
burner limit switch.
4.5.2.10 Vent Limit Switch
Probe for voltage at point 10, which is the gas valve
terminal having a brown wire connected to it. As in the
preceding case, this terminal will have voltage present
only during a trial for ignition or during normal operation.
If voltage is not found, the vent limit switch is open,
indicating that the exhaust temperature has been too high.
Normal vent temperature is between 100oF and 140oF.
Excessive temperature might be due to excessive water
temperature or overfiring of the system. Investigate
water temperature and possible water flow deficiency.
Confirm that the heater is equipped for the correct fuel
gas - especially that propane gas is not being provided to a
heater configured for natural gas. To confirm correction of
the problem, re-set the switch by pushing the red button. If
vent temperature is normal and the switch will not allow
operation, replace it.
WARNING
The combustion blower, the igniter and some terminals
of the ignition control utilize 115V power and require
appropriate servicing precautions. Note that wires and
terminals of these components may be “hot” even
when the component is not operating.

certaines bornes de la commande d’allumage utilisent
une alimentation de 115 V et exigent des mesures
d’entretien appropriées. Veuillez noter que les fils et les
bornes de ces composants peuvent être sous tension
même lorsque le composant ne fonctionne pas.
4.5.2.11 Combustion Blower
The combustion blower operates when it is provided
with 115V, 60 Hz power. Confirm this by connecting the
voltmeter between the “neutral” wirenut and point C, which
is the terminal marked F2 on the ignition control. Unless
the system is in lockout, 115V should be present at point C
whenever a call for heat reaches the venturi pressure switch
(i.e. 24V at point 6). To be sure that a lockout condition is not
in effect, turn the heater off and then back on at the control.
If 24V is present at point 6 but 115V does not appear at
point C (and there is no lockout) the ignition control is
defective. If 115V power is available at point C and the
combustion blower does not run, the blower is defective
and should be replaced. Note, however, that the blower
has an internal overtemperature limit and before replacing
it confirm that the environment of the heater is not
excessively hot. If so, ventilation of the heater room may
be necessary.
4.6.1 Pressure Measurement Ports
Figure 33 shows venturi and gas control components
and service port locations. Air flow enters the venturi
from below through the filter box. It is pulled through
a converging section to the throat, where pressure is
reduced substantially. Gas flow is pulled into the throat
through an orifice inside the pipe between the throat and
the elbow. Air and gas are combined in the throat and mix
thoroughly as they proceed through the venturi tailpipe to
the burner.
Service ports are provided at three (3) places. On the right
side of the venturi an inlet service port is provided just
above the air filter box. Also on the right side, a throat
service port is provided - at the narrowest section of the
venturi casting. A gas valve service port is provided on the
outlet face (right side) of the gas valve.
To evaluate system operation requires accurate
measurement at these ports. A digital manometer, known
to be accurately calibrated, is ideal. Other instruments
may be used, but the “positive/negative” nature of the
readings must be very clear. Also, gas pressure offset
measurements are at very low levels (0.2” WC) and
the instrumentation must be capable of determining it
accurately.

4.5.2.12Igniter
The igniter should glow during ignition attempts as outlined
in the earlier section on ignition control. If it does not,
connect the voltmeter between terminals marked D and E
on the ignition control. If 115V is present during the igniteron portion of the ignition sequence but there is no glow,
the igniter is probably defective. If voltage is not found, the
ignition control is defective and should be replaced.
An igniter which will not glow should be checked by
disconnecting the wires from the ignition control and
measuring the igniter resistance. A cold igniter should
have resistance in the range of 40 to 75 ohms. Replace the
igniter if resistance is outside of this range.
4.6
Venturi Combustion Flow System
Verifying proper operation of the comustion flow system
has two (2) aspects - air flow and gas flow. Air flow
is checked by measuring pressures at service ports on
the venturi. Gas flow is checked by evaluating venturi
pressures plus the regulator offset pressure and the gas
orifice size.
In a venturi flow system the difference between various
pressures is far more important than their “gauge” value
relative to the room. The gas pressure offset and the
gas orifice pressure differential are especially important
concepts. The following sections illustrate these and
related information.

4.6.2.1 Gas Orifice Differential
This measurement indicates how much “pull” is available
to move gas through the orifice. Turn off the heater
and connect the manometer tubes with the positive side
connected to the gas valve service port and the negative
side to the venturi throat service port as shown in Figure
34. Turn on heater. The manometer will read zero until
the gas valve opens, and then it will indicate the gas
orifice differential. The gas orifice differential should
be 4.0” ± 0.3” WC for a unit at sea level. See section on
High Elevation Operation for other elevations.

-
Note the reading and turn off the heater at the control.
Then go on to the next measurement - gas pressure offset.
4.6.2.2 Gas Pressure Offset
Note that an equalizer tube is connected from a port on
the front of the venturi inlet to the vent of the gas valve
regulator. This is a very important component which
allows the regulator to track air pressure even when
abnormal things occur, such as blockage of the combustion
air. Before firing, confirm that this tube and the venturi
pressure switch tubes are in place and firmly connected.
Figure 34. Gas orifice differential measurement.
+
-
Connect the positive side of the manometer to the venturi
inlet service port, which is at the bottom on the right
side. Connect the negative side of the manometer to the
gas valve service port, see Figure 35. Turn the heater on.
Until the heater fires, the manometer will indicate several
inches of water pressure, but after the gas valve opens, it
will indicate the gas pressure offset, which should be 0.2”
± 0.1” WC - i.e. the gas pressure should be 0.2” WC less
than the pressure at the venturi inlet service port.
If the offset is incorrect, adjust the gas pressure regulator
to the correct pressure. This can usually be done while
the heater is firing, but the burner may go off when the
regulator seal cap is removed. In any case, the offset
pressure measurement must be read when the heater is
operating and the seal cap is firmly in place. Note that a
special tool is required to remove the regulator cap.

4.6.3 Air Flow Investigation
If gas pressure offset is correctly set but gas orifice
differential is abnormal, check air flow through the system
per the following sections.
4.6.3.1. Unfired Venturi Differential
Pressure.
Determine if air flow through the system is in a normal
range by operating the system with the gas valve turned
off. Connect the positive side of the manometer to the
venturi inlet service port, which is at the bottom on the
right side. Connect the negative side of the manometer
to the gas valve service port of the gas valve, see Figure
37. Turn the gas valve knob to "Off". Turn the heater
on by selecting "Pool" or "Spa" at the control and
adjusting the temperature setting high. The blower will
start immediately and the manometer will indicate the
"unfired venturi differential" pressure. This is the pressure
difference created by airflow through the venturi. It should
be approximately 4.7" ± 0.3" at sea level. See Section
4.6.5 for other elevations.
Note that when the heater is operated with the gas valve
off, it will eventually “lock out” because the ignition
control does not sense flame. Normally there will be
enough time to obtain the measurement, but if necessary,
additional blower operation can be induced by turning the
Flex-Temp control off and then back on again.

Figure 37. Unfired venturi differential measurement.
If the reading is not normal, attempt to correct it by
blower speed adjustment. Blower speed is adjusted by
turning a special screw on the right side of the motor - at
about 4 o’clock, see Figure 38. A small countersunk hole
is provided there for access to the screw, but is covered by
a thin silver-colored label. Remove or puncture the label.
A small flat-blade screw driver is required. It must have
a 3/32” or 2.5 mm (.098”) blade and must be about
4-1/2” long. A jeweler’s screw driver or an electronics
pot adjustment screw driver (with handle cut short if
necessary) can be used. Insert the screw driver through
the hole on the motor housing. Turn it clockwise to
increase the flow and counter-clockwise to decrease.
If blower speed adjustment results in acceptable venturi
differential, shut off the system at the Flex-Temp control
and return to “Gas orifice differential” measurement
per Section 4.6.2.2. Make a final speed adjustment as
necessary to obtain correct gas orifice differential.
If the system cannot be made to operate normally by
blower speed adjustment, investigate possible flow
problems per the following sections.

4.6.3.2 Combustion Air Flow
Begin by connecting the negative side of the manometer
to the venturi inlet and leaving the positive side open to
ambient, as shown in Figure 39. In a normally operating
heater, the pressure will be 0.2 to 0.6" WC less than
the ambient pressure. For a model 350 with clean filter
and no combustion air duct, the reading will be near
the middle. If combustion air is ducted to the heater,
the reading will be near the high end. If an excessive
reading is observed (i.e. more negative), flow is probably
restricted by a dirty filter or blockage in the combustion
air supply system. Correct any such problems and verify
normal operation by returning to the venturi system
checkout procedures.
Pressure readings will be less if the heater is located at an
elevation significantly above sea level.
Jandy® Pro Series, Hi-E2® and Hi-E2®R Gas-Fired Heater | Installation & Operation Manual
4.6.3.3 Flow in Heater and Vent
If the venturi inlet pressure reading is normal (or less
than normal), flow may be blocked within the heater or
in the exhaust venting, or the combustion blower may be
operating below standard. To evaluate this, connect the
negative side of the manometer to the collector pressure
tap, as shown in Figure 40, leaving the positive side open
to ambient (this requires a pressure tap with a 1/4" NPT
thread). When the heater is operating, the pressure at this
location should be about 2.8 ± 0.5" WC less than ambient
for a model 350. If a greater reading is observed (i.e.
more negative), flow is restricted within the heater, most
likely at the burner or the heat exchanger. If the reading
is substantially less (i.e. less negative), the combustion
blower is not operating properly or flow is blocked
after the blower, possibly in the vent. Correct any such
problems and verify normal operation by returning to the
venturi system checkout procedures.
Pressure readings will be less if the heater is located at an
elevation significantly above sea level.

4.6.4 Fuel Gas Type and Gas Orifice Size
Zodiac® configures its heaters for natural gas with 0.60
specific gravity and 1035 BTU/Ft3 or for propane gas
with 1.52 specific gravity and 2500 BTU/Ft3. Required
gas orifices are listed in the replacement parts list. Consult
your Jandy Pro Series representative if the available gas is
substantially different.
4.6.5 High Elevation Operation
The venturi combustion flow system completely
compensates for installation at elevations other than
sea level. Gas orifice changes are not necessary. Unlike
conventional systems with open type burners and positive
pressure regulators, the gas orifice differential pressure
is created by the air flow, and it is automatically reduced
when air density decreased. A Hi-E2 heater commissioned
at sea level will operate at nearly the same air/gas mixture
when operated at higher elevation. Its firing rate will
decrease about 3% per 1000 feet due to the barometric
pressure change.
In servicing a Hi-E2 heater at high elevation be aware
that the input will be naturally reduced by this amount
and that the differential pressures, as discussed in prior
sections, will also be reduced. Pressure readings at various
elevations will be approximately as follows:
Elevation
Ft (m)
Sea Level
Gas Orifice
Unfired Venturi
Differential
Differential
4.0" (102 mm) WC 4.7" (119 mm) WC

The gas pressure offset is determined by the regulator spring adjustment, not air
density. It is not affected by elevation change.

Combustion Condensate
The condensate disposal system of the Hi-E2 pool
heater is quite simple, but must be properly installed
and maintained. See the installation instructions for
information on correct tubing installation. Condensate
drainage should be observed routinely and if necessary,
the flow-ways should be cleaned.
In normal operation, condensate drains from the
condensate collector behind the combustion fan. A 5/8"
I.D. drain tube conducts this water into the condensate
trap/neutralizer, where a “water seal” prevents room
air from being pulled into the system. The water seal of
the trap prevents vent gases from being discharged into
the room. A smaller amount of condensate may drain
from the vent duct and blower. See Figures 12 and 13
in the Condensate Disposal section of the installation
instructions.

ENGLISH
Jandy® Pro Series, Hi-E2® and Hi-E2®R Gas-Fired Heater | Installation & Operation Manual
During start-up, condensate from the collector cannot
reach the trap unless the water seal is established. This
can be done by pouring water into the trap. The heater
will self-prime by driving water into the vent outlet, from
which it will eventually drain into the trap. However, it is
better to avoid this by manually priming the trap.
If condensate is not draining from the system, check
for improper routing of the drainage tubes or blockage
in the drainage system. Tubing must be installed with a
continuous fall in the direction of condensate flow. Sags
may trap water, defeating the intended operation. Check
for blockage by disconnecting drainage tubes at the
collector and the vent diffuser. Probe these openings with
a tool or wire hook to dislodge any debris.
Limestone gravel neutralizer is required in the condensate
tray to prevent corrosion. This material should be replaced
once a year to assure its continuous benefit. Replacement
packages are available from Zodiac® or its representatives.
It is normal that a blue/green deposit forms in the
neutralizer. This is caused by very small concentrations of
copper ions present in the condensate. By increasing the
pH of the condensate, the limestone causes this material
to precipitate and be retained in the gravel.

Major Component Service
The venturi assembly, the burner assembly and the heat
exchanger tube assembly can be replaced if necessary,
but correct procedures and use of only factory-provided
parts are essential to assure satisfactory service and safe
operation. Sealing the system with the specified sealers
and gaskets is especially important. Contact Zodiac®
Technical Support for information.

General Information
NOTES:
1.
The Hi-E2 is design certified by CSA International
as a swimming pool heater under ANSI Standard
Z21.56 for use in the United States and Standard
CSA-4.7 for use in Canada.
2.
The Hi-E2 pool heater is certified for use indoors
or outdoors in the United States.
3.
The Hi-E2 pool heater is for use with natural or
liquefied petroleum gas. Ratings apply to either
fuel.
4.
De-rating for elevation is not necessary because
of the Hi-E2 heater's special combustion
system. Reduced barometric pressure at high
elevations naturally decreases input and output by
approximately 3 percent per 1000 feet above sea
level.
5.
Heaters require 115V, 60Hz electrical power.
6.
Working pressure 75 psig.
