Model ESG Pool and Spa Heater
SECTION 1.
General Information
1A. Introduction
This manual provides information for the proper
installation, operation and maintenance of the Series
2 Model ESG millivolt pool heater. The American
Gas Association design-certifies the Series 2 heaters
as complying with the latest edition of the Standard
for Gas-Fired Pool Heaters, ANSI Z21.56. In
Canada, CGA certifies that the heaters comply with
standard CAN1-4.7-M85. Check local and state
codes before beginning the installation.
Certain Sections of this manual are specific to
either United States or Canadian installations, and
are labeled as such.
The Installation, Operation and Maintenance
manual must be followed exactly. Copies of this
manual are available from the factory: 6000 Condor
Drive, Moorpark, CA 93021, attn: Literature Dept.
1B. Description
The Model ESG is a compact, high performance
pool/spa heater. It does not require connection to an
external electrical source. The heater converts heat
from the pilot into electricity which operates the
controls.
Teledyne Laars specifically designs this appli-
ance to heat fresh water swimming pools and spas.
Do not use it as a heating boiler or general service
water heater. For special applications, including salt
water installations, consult your Teledyne Laars
dealer.
Teledyne Laars ships the heater with the water
connections on the right side. It could be necessary,
or helpful, to move the connections to the left side
for improved service access. Instructions for making
this change are in Section 5. The procedure should
only be done by a professional service technician,
qualified in pool heater installation and maintenance.
1C. Warranty
Teledyne Laars sells the Series 2 heater with
a limited factory warranty. A copy of the warranty is
on the back cover of this manual.
The home owner should fill out the warranty
registration card included in the plastic bag and
return it to Teledyne Laars.
The warranty does not cover damage caused by
improper installation or field modification, or to the
heat exchanger by corrosive water. Section 3G
explains proper pool water chemistry.
SECTION 2.
Installation Instructions
2A. General (United States)
(See page 2 for Canada)
All gas-fired products require correct installation
to assure safe operation. The requirements for pool
heaters include the following:
Appropriate site location (clearances).
Non-Combustible surface.
Sufficient combustion air and ventilation air.
Adequate venting (products of combustion).
Froperly sized gas pipe.
Adequate water flow.
Regular maintenance.
aa de CAN
The heater must be installed at least five feet
from the inside wall of the pool or spa unless sepa-
rated from the pool or spa by a solid fence, wall or
other permanent barrier.
The National Fuel Gas Code offers general
guidelines for combustion air, ventilation air, and
venting. Follow these criteria to insure a safe,
efficient installation.
Select the heater location to permit satisfactory
air supply for proper venting, and to allow space tor
maintenance access. Recommended clearances are
specified in Section 2B and 2C.
Locate the heater in an area where leakage of
the heater or connections will not result in damage to
the area around the appliance or to the structure.
Where such locations cannot be avoided, install a
suitable drain pan, adequately drained, under the
heater. This pan must not restrict air flow.
Figure 1. Non-Combustible Platform
IT TELEDYNE LAARS
Except as noted below, install all heaters on a
non-combustible surface. A surface consisting
entirely or a combination of steel, iron, brick, tile,
concrete, slate, glass or plaster would be non-
combustible.
You can install the heater on a combustible floor
by placing a non-combustible base under the heater,
available from Teledyne Laars. See the rating plate
for the base part number. Do not install heaters on
carpeting.
The Fuel Gas Code permits a heater to be
placed on a combustible surface when the installa-
tion complies with the American Insurance Code.
This code specifies that there is a platform under the
heater constructed of hollow masonry no less than 4”
thick, covered with sheet metal at least 24 ga. thick.
The masonry must be laid with ends unsealed, and
joints matched to provide a free circulation of air
from side to side through the masonry (see Figure 1).
Safe operation at the proper manifold pressure
requires correct sizing of supply gas pipe. The
National Fuel Gas Code also offers general criteria
for gas piping (see Section 2E).
If the above installation requirements are not
followed, the fuel used in these appliances could
produce and expose you to substances that are
known to cause cancer or reproductive harm.
Install the heater in accordance with all local
codes and ordinances and the most recent edition of
the National Fuel Gas Code, ANSI 2223.1.

Special Precautions for LP Gas Heaters
LP gas is heavier than air. Therefore, do not
install pool heaters using LP gas in pits or other
locations where gas might collect. Locate the heaters
a safe distance from LP gas storage and filling
equipment. Consult local codes and fire protection
authorities about specific installation restrictions.
2B. Outdoor Installation
2B-1 Heater Clearance
Locate the heater in an open, unroofed area, and
maintain the following clearances:
Blank Side and 6" Minimum

Figure 2. Outdoor Heater Location
Do not install the heater in a location where
leaves or other combustible materials can accumu-
late around the base or on the top.
Do not locate the heater close to sprinklers; the
water could damage the controls and the electronics.
If you are installing the heater under an over-
hang, there must be a minimum clearance of 3 feet
above the top of the heater. The area under the
overhang must be open on three sides. This prevents
combustion gases from being diverted into living
areas through doors, windows or gravity inlets.
Protect the heater from direct water drainage.
AWARNING
In United States
Do not install the heater with the top of the vent
assembly within 4 feet of any opening into a
building (see Fig. 2).
In Canada
Do not install the heater with the top of the vent
assembly within 10 feet of any opening into a
building (see Fig. 2).

the National Fuel Gas Code for more information .
tag when the conversion is made.
2D. Outdoor Shelter Installation (Canada
Only)
The Series 2 heater is certified for installation in
an outdoor shelter only when equipped with a draft
hood (An outdoor shelter is an enclosure not nor-
mally occupied which does not communicate directly
with occupied areas). Check the rating plate for the
correct Teledyne Laars draft hood part number, See
instructions supplied with the draft hood for installa-
tion and attachment. When the draft hood is used,
locate the heater so as to be in the same atmo-
spheric pressure zone as the combustion air inlet to
the heater.
Connect the draft hood to a vent pipe which
stops at least two feet above the highest point of the

If the heater is installed in a residential garage,
or where flammable vapors will be present, the
burners must be 18" above the garage floor. See
Gas Installation Code CAN/CGA B149, latest edition.
2E. Gas Supply and Piping
Heaters shipped from the factory are certified to
operate at an altitude of 0 to 2000 feet or, if so
ordered, at higher altitudes.
In United States:
The heater manifold is marked with a tag or sticker
for appropriate high altitude operation.
High altitude (H) is 2,000 to 6,000 feet and
High altitude (J) is 6,000 to 10,000 feet above
sea level.
In Canada:
High altitude (H) is 2,000 to 4,500 feet above sea
level.
The heater rating plate is marked for specific
altitude requirements.
Teledyne Laars recommends the gas inlet pipe
sizes in Table 3. Check local codes for compliance
before installing the heater.

2F. Electric Wiring
AWARNING
Do not connect the heater to any external
source of electricity. The Teledyne Laars Series
2 ESG heater has a built-in thermoelectric’
generator. It provides a completely self-con-
tained electrical system. Any attempt to make
electrical connections to an external source will
| damage the heater, and could be hazardous.
See Figure 5 for typical wiring diagram.
2F-1. Auxiliary Time Clock Wiring
If you install a time clock to control the filter
pump operation, the clock must have its own low
voltage (Fireman's) switch to turn off the heater
before turning off the pump. The switch should shut
off the heater about 15 minutes before the filter
pump shuts off.
To install a time clock auxiliary switch into the
heater wires, follow these steps (see Fig. 6):
1. Remove the service door.
2. Remove the factory installed wire between
terminals 1 and 2 on the terminal strip (see
Fig. 7).

3. Connect the wires from the time clock auxiliary
switch to the two terminals. Use AWG #14 ga
copper wire with a temperature rating of 105°C or
greater.
The length of the wire between the heater and
the time clock should not exceed 15 feet. The
contact points of the time clock switch should be
silver, or a low resistance alloy.
2G. Water Piping
You can connect high temperature plastic piping
{CPVC Schedule 80) directly to the inlet/outlet
header if local codes allow it, and the controls keep
the filter pump running at least 15 minutes after the
heater is turned off.
The heater has 2" universal header couplings.
You can connect threaded 2° iron pipe, unthreaded
1-1/2" iron pipe, 1-1/2" or 2° copper pipe without an
adapter and CPVC pipe by removing the cast iron
flanges and installing the “No Sweat"™ flanges
provided with the heater (see Fig. 8).
You can use plastic materials in pipes, fittings,
grids and other elements of the filter system if
acceptable by the authorities having jurisdiction. If
unacceptable, use a metal “heat sink” pipe between
the filter and the heater as shown in Figure 10.

“back-siphoning” when the pump stops. Do not install
any other valve or variable restriction in the piping
between the heater outlet and the pool, unless it is
being used as a diverter valve.
2G-1. Automatic Chlorinators (Chemical Feeders)
An excessive concentration of chlorine (or other
chemical) in the pool heater can be very destructive.
Heater damage caused by an excessive concentra-
tion of chlorine is not covered by the Teledyne Laars
warranty. See Section 3H for recommended levels.
IMPORTANT: Equip the chlorinator with an anti-
siphoning device so that chlorine will not siphon into
the heater after the pump shuts off.
Wire the chlorinator so it cannot operate unless
the filter pump is running. If the chlorinator has an
independent clock control, be sure the filter and
chlorinator clocks are synchronized.
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.
2H. Pressure Relief Valve
A pressure relief valve is not furnished with the
Series 2 heater except in Canada. Local plumbing
codes may require it. To install a pressure relief
valve, remove the 3/4" brass plug on top of the
header and screw in the valve (see Fig. 9). The
setting of the valve should be at or below the lowest
working pressure of any component in the filter
system.
2J. Pressure Switch Adjustment
The pressure switch is pre-set at the factory for
normal pool installations. Do not adjust the pressure
switch unless the installation involves special condi-
tions such as:
1. If the top of the heater is installed three (3) feet
or more below the surface of the pool.

2. If any part of the filter system piping is three (3)
feet or more above the top of the heater jacket.
If either of the above conditions exist, follow the
detailed instructions in Section 4C.
NOTE: Do not make the pressure switch adjustment
if the heater is installed more than 15 feet below or 6
feet above the pool surface. Consult Teledyne Laars
for recommendations.
On some installations, the piping from the heater
to the pool is very short. The back pressure could be
too low to trigger the pressure switch. If this happens,
it may be necessary to install a directional fitting, or
elbows, where the return line enters the pool. This
will increase back pressure enough for the heater to
operate properly.
2K. Temperature Rise
When the installation is complete, the last thing
the installer should do is take a temperature rise. Use
the data in Table 5 to verify proper water flow
through the heater.
An automatic, built-in by-pass valve maintains
proper flow through the heater at flow rates less than
125 GPM. If the system filter-flow rate exceeds 125
GPM, a manual by-pass valve is required. Fig. 10
shows a valve installed between the heater inlet and
outlet. To set the bypass valve, follow this procedure:
1. Clean the pool filter.
2. With the filter pump off, remove the drain valve.
The valve is located on the right side of the
heater. Replace the drain valve with a thermom-
eter (see Fig. 9).
3. Close the manual by-pass valve.
4, Make sure the heater is OFF by moving the
rocker switch to the "OFF" position.
5. Start the filter pump.
6. After 3 minutes, note and record the thermome-
ter reading (this represents pool water tempera-
ture).
7. Follow the procedures on the Lighting and
Shutdown label located inside the control com-
partment to turn the heater on.
8. Let the heater run for at least five minutes before
noting and recording the new thermometer
reading.
9. If the temperature reading is outside the MIN.

Operating Instructions
Section 3A. Start-Up Procedure
FULL LIGHTING AND SHUTDOWN INSTRUC-
TIONS ARE INCLUDED ON THE LABEL AT-
TACHED INSIDE THE SERVICE DOOR.
AWARNING
Vent pipes, draft hoods, tops and water fittings
get hot! These surfaces can cause serious
burns, so do not touch these surfaces when the
heater is operating. The addition of a vent cap
will reduce the temperature on the top.
When lighting or relighting the pilot, always turn
the temperature control to its lowest setting. Tum the
rocker switch to OFF.
With any new pool or spa installation, operate
the filter pump with the heater off long enough to
completely clean the water. This will remove any
installation residue from the water. Clean the filter at
the end of this operation before starting the heater.

I TELEDYNE LAARS 5
Figure 11. ESG Temperature Control
When raising the temperature of 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 automatically shut off, but
the filter pump will keep running. The filter pump
must continue running for at least 15 minutes after
the heater shuts off to prevent damage to the system
piping.
NOTE: Keep all objects off the top of the heater.
Blocking air flow could damage the heater, and void
the warranty.
3B. Temperature Control
The temperature control (see Fig. 11) is cali-
brated at the factory. It covers a range from approxi-
mately 70°F (21°C) to 104°F (40°C). Use an accu-
rate pool thermometer to determine the best water
temperature for your uses. After positioning the
control knob at the desired setting, use the TEMP-
LOK to keep it from going any higher.
3C. Lighting and Shutdown
3C-1. Lighting the Heater
AWARNING
For your safety when lighting the heater, keep
your head and face well away from the lower
firebox opening to prevent any risk of personal
injury.
Full lighting and shutdown instructions can also
be found attached to the wall inside the control
compartment door,
1. Remove the service door on the front of the
heater. Make sure the gas valve control knob is in
the OFF position. If not, turn the knob clockwise
to the PILOT position, then depress slightly and
continue turning clockwise to OFF (see Fig. 12).
Model ESG Pool and Spa Heater
AWARNING
For LP Gas: To avoid possible injury, fire and
explosion, read and follow these precautions and
all instructions on this appliance before lighting the
pilot. This appliance uses LP (Propane) gas which
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 depart-
ment 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 re-filled, the appliance
must be re-lit according to the instructions located
on the inside of the door. DO NOT attempt repairs
on the gas control or appliance. |
Tampering is dangerous and voids all warranties.

2. Wait 5 minutes. It takes that long for the natural
air flow to clear any buildup of unburned gases
from the combustion chamber. These gases
could ignite if you try to light the heater too soon.
3. Turn the gas valve control knob counter-clock-
wise to the PILOT position.
To light the pilot, push the gas valve control knob
down and rotate the sparker knob (see Fig. 13).

10. Set the temperature control against the TEMP-
LOK tab. The heater should come on. Until the
water reaches a temperature of about 70°F
(21°C), it is normal to have some water accumu-
lating in the base of the heater.
11. Set the time clock if one is installed.
3C-2. Relighting
If the pilot goes out, repeat steps 1 through 11.
NOTE: If over-heating happens, or the gas supply
fails to shut off, turn off the main burners only. You
can either position the rocker switch to OFF, or open
the service door and rotate the gas valve knob to
PILOT.
For a complete shutdown, open the service door,
rotate the gas valve knob clockwise to PILOT.
Depress the knob slightly and continue turning
clockwise to OFF, or turn off the manual shutoff
valve located outside the heater,

3F. Winterizing
In areas where freezing temperatures occur and
you don't plan to use the pool or spa, have your
service technician perform the following steps:
1. Shut off the gas valve.
2. Completely drain the heater before the first frost.
To drain the heater, remove the drain plugs and
open all of the drain valves (see Fig. 14). After
the heater is drained, remove the valves. Make
sure there is no mineral buildup in the openings.
3. Grease the threads in the header for winter
protection, but don't close them off.
4. Disconnect the pressure switch copper tubing.
NOTE: When attaching the copper tubing to the
pressure switch in the Spring, fill the loop with SAE
50, non-detergent oil as indicated in Figure 15.
5. Use compres- cu air to blow out any standing
water in the heat exchanger.
3G. Water Chemistry
3G-1. For Pool
Due to natural evaporation and the addition of
algicidal and sanitizing chemicals, the mineral
content of swimming pool water increases daily. If
the mineral concentration in the pool gets too high,
the minerals will precipitate out of the water and
deposit on the walls of the pool, in the filter system,
and in the heater tubes. To protect your heater from
damage, you must take the precaution of maintaining
the pH factor of the pool water between 7.4 and 7.6.
Do not place chemicals in the. pool skimmer drain.
3G-2. For Spa
The control of chemical balance in à spa is more
critical than a swimming pool for satisfactory heater
operation.
Model ESG Pool and Spa Heater
Usage density in a spa is many times greater
than a swimming pool. The size, higher water tem-
perature, and heavy usage, mean chemical values in
spas can differ greatly. The lack of the right chemical
content can result in unsanitary water conditions, and
affect the life of the heater.
Maintaining sanitary water conditions in a spa
can only be done by regular water changes and the
addition of sanitizing chemicals.
3G-2a. Corrosion
The corrosive action of spa water is increased by
the following:
a. Low pH - acidity
b. Low Total Alkalinity - bicarbonates
с. Low Calcium Hardness - soft water
NOTE: Teledyne Laars does not warrant heat
exchangers damaged by corrosive water.
3H. Testing
Teledyne Laars recommends that owners
purchase a test kit and use it regularly. A minimum
kit is one which will measure chlorine, pH level and
alkalinity.

3J. Therapeutic Pool (Spa) Safety Rules
Therapeutic pools, or spas, are piped so that
very warm water, often with air injection, enters a
confined area of a swimming pool or a small sepa-
rate pool at high velocity. The use of these pools can
be hazardous unless you comply with the following
U.S. Consumer Product Safety Commission “Safety
Rules for Hot Tubs.”
1. 104°F (40°C) is the maximum temperature for
spa or hot tub water. 100°F (37°C) is considered
safe for a healthy adult. Special caution is
recommended for young children.
2. The 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.
3. Pregnant women beware! Soaking in water
above 102°F (38.5°C) can cause fetal damage
during the first three months of pregnancy (which
could result in the birth of a brain-damaged or
deformed child). If pregnant women are going to
use a spa or hot tub, they should make sure the
water temperature is below 100°F (37°C).
4. Check the water temperature with an accurate
thermometer before entering a spa or hot tub.
Thermostats may vary by as much as 4°F.
5. Persons with a medical history of heart disease,
circulatory problems, diabetes, or blood pressure
problems should consult their physician before
using a hot tub or spa.
6. Persons taking any medication which induces
drowsiness, such as tranquilizers, antihistamines,
or anticoagulants should not use spas or hot tubs.
7. 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 tem-
perature,
The effects of hyperthermia include:
Unawareness of impending hazard
Failure to perceive heat
Failure to recognize need to leave spa
Physical inability to leave spa
Fetal damage in pregnant women
Unconsciousness resulting in a danger of
drowning

JK. Swimming Pool Energy Savings Tips
Teledyne Laars offers the following recommen-
dations to help conserve fuel. These recommenda-
tions will reduce the cost of operating your pool
heater without sacrificing comfort.
1. The Red Cross recommends a maximum water
temperature of 78°F (25°C). Use an accurate
pool thermometer. A difference of 4 degrees,
from 78°F (25°C) to 82°F (28°C), will use as
much as 40% more gas.
2. Carefully monitor the water temperature of your
pool in the summer time. You can reduce heater
usage due to warmer air temperatures.
3. Find the proper setting on the pool heater
temperature control. 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
balances.
5. If the pool is only going to be used on week-
ends, reduce the heater thermostat setting by 8
or 10 degrees during the week. Reset it to the
78°F (25°C) level a day or so before you plan to
use the pool.
6. During the winter, and when on vacation for
longer than a week, follow the instructions in
Section 44-3 and 4-F to shut down the heater.
7. Where possible, shelter the pool from prevailing
winds with well-trimmed hedges or other land-
scaping, cabanas, or fencing.
В, 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.
3L. Periodic Inspection
AWARNING
Improper installation or maintenance can
cause nausea or asphyxiation from carbon
monoxide or flue gases which could result in
severe injury or death.

tions. Have regular inspections at least annually by
trained service personnel to keep the heater operat-
ing efficiently. The service technician should check
the following:
1. Keep the top of the heater clear of all debris.
Make sure there is no collection of flammable
materials, leaves, paper, etc. under the heater.
2. Inspect the internal surfaces of the heat ex-
changer tubes annually. Remove any buildup of
scale,
3. Inspect the external surfaces of the heat ex-
changer tubes for soot buildup by placing a
mirror between and under the burners when the
heater is firing. Remove soot if it has collected
on the tubes, and correct the cause.
4, Check for spider webs in the pilot and main
burner orifices - especially at Spring start-up.

Controls can deteriorate over a period of years.
A regular inspection schedule, with repair or replace-
ment as needed, will keep the heater performing
properly.
7. Keep the pool heater area clean and free of all
combustible materials, gasoline and other
flammable vapors and liquids.
8. Do not use the heater if any part has been under
water. Immediately call a qualified service
technician to inspect the heater and to replace
any part of the control system and any gas
control which has been under water.
Keep this manual in a safe place for future
reference by you and your qualified service techni-
cian when inspecting or servicing the heater.
SECTION 4.
Maintenance
IMPORTANT: A professional service technician,
qualified in pool heater maintenance should use the
material in this section for testing and repairing the
heater. It includes step-by-step procedures for
trouble-shooting the electrical control system and
other parts of the heater. Review these procedures
before beginning repairs.
4A. Gas Pressure Tests
One of the first steps in trouble-shooting the
heater should be checking inlet and manifold gas
pressure with a manometer. A manometer kit is
available from Teledyne Laars.
All of the other parts of the pool system have an
effect on heater operation. These parts include the
pump, filters and strainers, valves, gas supply, and
time clocks. Before going on with these heater-
related trouble-shooting procedures, make sure the
pump is operating properly, the filter and strainers
aren't clogged, there are no closed valves in the
piping system, and the time clocks are properly
adjusted. If all of these components check out, then
proceed with the following trouble-shooting proce-
dures.
4B. Electrical Trouble-shooting
The following step-by-step procedures will
W TELEDYNE LAARS
Page 14
identify problems which may cause heater malfunc-
tions. Before starting these procedures, review the
information in the Installation and Operation sections
of this manual. Make sure every other part of the
pool system is operating properly before starting this
procedure.
Sa
1. Develop a routine for trouble-shooting heaters.
2. Keep all chemicals away from heaters.
3. Never put your face near the lower section of a
heater after you have turned the gas on, or it is
firing. Use a mirror to inspect the flame pattern.
Tools Needed
1. A good multimeter with a 2 volt DC scale and a
200 MV scale.
2. A manometer for testing gas pressure.
3. A Pete's plug and thermometer to measure
temperature rise.
4, Basic hand tools.
5. A hand mirror.
6. A back pressure tester.
General
1. Make sure the pool filter system is clean.
2. Make sure all electrical connections are tight,
and none of the wires are frayed or broken.
Replace them if necessary.
3. Make sure the heater model number agrees with
the wiring diagram.
4. Follow this test procedure one step at a time. Do
a test, correct any problem discovered, then go
to the next step.
5. Take your time. Don't rush a test, and don't skip
any of the steps in a sequence.
This part of the trouble-shooting guide will cover
four problems:
4E-1, Pilot will not light.
4E-2, Pilot will not stay lit.
4E-3. Main burners will not light.
4E-4, Intermittent operation.

Follow the lighting instructions in the Operation
section of the manual to light the pilot (these instruc-
tions are also located inside the heater front panel).
4B-1. Pilot Will Not Light
The first thing to check is the supply gas pres-
sure. If the supply gas pressure is low, check these
possible causes:
Improper installation.
The gas meter is too small.
The gas line is too small or restricted.
Too many appliances sharing the gas line.
Manual gas valves outside the heater are
closed.
PACO
If the manometer test shows the main supply
gas pressure is high enough, but the pilot will not
light, check the following:
Is the pilot burner dirty or clogged?
Is the Piezo lighter sparking (see Fig. 18)7
Does the pilot have the correct orifice?
Is the pilot burner gas tube loose or detached?
Is the pilot properly aligned (see Fig. 19)?
PACO
These questions can only be answered by
removing the burner tray from the heater jacket.
Follow the procedures in Section 4F to pull the
burner tray out far enough to check the pilot.
With the wire still attached between the Piezo
lighter and the pilot, twist the Piezo knob to verify it
is sparking at the pilot. If not, replace the Piezo
lighter assembly.
After answering these questions, and correcting
any problems, the pilot should light.

3. Touch the black meter lead to terminal TH/TP
on the gas valve (see Fig. 20).
4. Set the meter on the 2 volt DC range.
5. Turn the knob on the gas valve to PILOT.
6. Push the knob down and twist the sparker to
light the pilot. Hold it down for at least 30
seconds.
7. When the pilot lights, the meter should build up
to about 500 MV while you are holding the knob
down.

8. If the meter does not register at least 500 MV,
replace the pilot generator.
9, Secure the red wire back on terminal TP.
10. Attach the black multimeter lead to terminal TP
on the gas valve (see Fig. 21).
11. Attach the red lead to terminal TH/TP.
12. Push the knob down to light the pilot.
13. If the meter registers less than 500 MV after the
pilot lights, release the knob. If the pilot does not
stay lit, check the following:
The pilot generator is weak or defective. Test
the generator by moving the wires where they attach
to the generator and watch the meter. If the meter
reading jumps, replace the generator.
If the pilot generator checks out, test for shorts
or grounded wires.
Figure 21. Closed Circuit Test
Redundant High-limit Test (see Fig. 22)
a. Attach the black meter lead to terminal TP.
b. Light the pilot, and keep holding the knob down.
c. Touch the red meter lead to the gas valve coil
connector pin.
If the meter registers 500 MV, replace the gas
valve. If no voltage, replace the redundant high-limit.
4B-3. Main Burners Will Not Light
If the main burners fail to light when there is a
call for heat, check the following possible causes.
a. Is the filter pump ON?
b. Is the filter clean, and is water flowing to the
pool?
с. Is the ON/OFF toggle switch ON?
d. Is the gas valve knob in the ON position?
e. Is the thermostat set to the maximum position?
f. Is the “Fireman” switch and time clock ON?
g. Are all auxiliary items turned ON (remote
thermostat, air switch, override switch, etc.)?

Figure 22. Redundant High-limit Switch Test
п. Is the pilot ON?
If the answer to all of the above questions is
YES, then continue to the next series of tests. Keep
in mind that if the pilot is lit, there is voltage in the
circuit. These tests are to determine where the break
in the voltage is occurring.
Fusible Link (see Fig. 23)
Place one meter lead on terminal TP on the gas
valve (this lead will stay on terminal TP during all of
these tests) and the other lead on each fusible link
terminal. If the meter shows voltage at one terminal
but not the other, replace the fusible link.
A bad fusible link can be symptomatic of an
installation problem. Check for downdrafts or sooting.
High-limit Switches (see Fig. 24)
With one meter lead still attached to terminal
TP, touch the other meter lead to the white wire
terminal of the pressure switch. If the meter shows at
least 500 MV, the high limits are good. If no voltage,
test the high limit switches individually. |
To test the limit switches individually, remove
the limit switch cover located under the In/Out
header. Remove the high limit retainer bracket. Pull
the two high limits out of their cavities. Test them
using the following procedure:
1. Pull the black insulation away from the silver
Figure 23. Fusible Link Test
limit switch to expose the terminals.
2. Keep the black meter lead attached to terminal
TP on the gas valve. Touch the other meter lead
to the terminals on the silver high limit switch. If
there is voltage at one terminal and not the
other, replace the high limit.
3. Repeat the same procedure for the red high
limit switch.
4. Make sure both high limits are good by touching
the meter lead to the white wire terminal on the
pressure switch again. Push the black insulation
back up to cover the terminals completely
before replacing them in the In/Out header.
5. When replacing the high limits in the header, the
red one goes in the lower cavity. The silver one
goes in the upper cavity.
Pressure Switch (see Fig. 25)
Keep the black meter lead attached to terminal
TP on the gas valve. Touch the other lead to the
black wire terminal on the pressure switch. If there is
no voltage, the pressure switch is keeping the heater
off. You need to determine whether it's the switch or
a back pressure problem.
If a pressure gauge registers 2 pounds or more,
the pressure switch could be out of adjustment,
YC TELEDYNE LAARS
Si
Figure 24. Testing High-limit Switches
defective, or the pressure switch tube could be
clogged. Repair or replace as necessary.
NOTE: Only adjust the pressure switch to turn the
heateroff, not on.
Pressure Switch Adjustment
The pool filter must be clean before making this
adjustment (see Fig. 26).
1. Turn the control panel rocker switch to OFF.
2. Set the POOL thermostat to MAX.
3. Start the filter pump.
4. Turn rocker switch to ON. Heater should start.
5. Turn the pressure switch adjustment screw
counter-clockwise very slowly until the heater
goes off.
6. Turn the pressure switch adjustment screw
clockwise 1/4 turn. The heater should come
back on.
7. NOTE: Check the adjustment by turning the filter
pump off. The heater should shut off immedi-
ately. If it does not, restart the filter pump and
Figure 25. Pressure Switch Test
repeat Steps 5 and 6. Check the adjustment.
8. Return the pool thermostat to the desired tem-
perature,
9. When the pressure switch is properly adjusted,
the heater should come on about 10 seconds
after the filter pump is started and shut off right
after the pump shuts off.
Thermostat and Rocker Switch (see Fig. 27)
With the black meter lead attached to terminal
TP, touch the red meter lead to the TH terminal on
the gas valve. If there is no voltage, the thermostat,
toggle switch or both are keeping the heater from
firing. Test the rocker switch independently by
touching the red meter lead to each of the terminals.
If the meter registers voltage at one and not the
other, the rocker switch is defective. Replace it. If the
heater still does not fire, the problem could be the
thermostat. Test the thermostat in the same way.
Gas Valve
With one meter lead still attached to terminal TP
on the gas valve, touch the other lead to terminal
TH. If the meter registers 500 MV and the heater still
does not fire, replace the gas valve.

4B-4. Heater Will Not Shut Off When the
Pump is Not Running
The main burners must not fire unless the filter
pump is running. This could be an indication of
improper installation, or the pressure switch could be
out of adjustment.
4C-5. Intermittent Operation (see Fig. 28)
High resistance in the safety circuit can cause
intermittent operation, and is a warning of future
problems. The following test will determine if there is
an excessive voltage drop (high resistance) in any
contact or control. Make sure the filter is clean, the
Figure 27. Thermostat & Rocker Switch Test
pump is running and the main burners are firing
before performing this test.
Connect a millivoltmeter between TH/TP and TH
on the gas valve. À reading of 20MV or less is
acceptable. This represents the total voltage drop
through the safety controls and wire harness.
Determine the voltage drop across the individual
components by using the meter leads to test across
the pressure switch, the thermostat, and the high-
limit switches one at a time. Add up the individual
voltage drops. À total of 20MV or less is acceptable.
If there is more than a 10MV drop across the
pressure switch, make sure the terminals are tight.
If there is more than a 10MV drop across the
thermostat, check and clean the spade terminals.
Tighten terminal screws on the thermostat. If this
does not reduce the voltage drop, replace the
thermostat.
If there is more than a 10MV drop across the
rocker switch, replace the toggle switch.
If there is more than a 10MV drop across the two
high-limit switches, check each switch individually.
Make sure the terminals are secure. If there is more
than a 10MV drop from one high-limit, replace it.
Accessory Equipment
Disconnect all accessory equipment from the
heater, such as time clocks. Make sure the heater is
properly wired according to the applicable schematic.
If the heater fires, the problem is in the accessory
equipment and not the heater. Replace or repair the
WTELEDYNE LAARS
equipment as needed,
If the heater still does not fire, repeat the above
electrical trouble-shooting procedures without the
accessory equipment attached. If it still fails to light,
consult your local dealer or Teledyne Laars.
4C. Replacing the Gas Valve
AWARNING
Never try to repair the gas valve. Such attempts
will void the warranty, and could lead to danger-
ous results. If the gas valve is defective,
replace it by following these instructions.
1. Turn off the main gas supply at the manual gas
cock or the meter.
2. Follow the shutdown procedures on the lighting
and shutdown label to turn off the gas valve.
3. Disconnect the main gas pipe from the gas valve
(see Fig. 28).
4. Remove the two screws securing the anti-rotation
bracket on the left side of the gas valve.
5. Remove the pilot gas tube from the gas valve.
6. Remove all wires from the gas valve terminals.
7. Unscrew the gas valve from the manifold pipe.
8. Screw the new gas valve onto the manifold pipe,
and finish the replacement by reversing the
above instructions.
9. Before operating the heater, test the complete
gas supply system, including all fittings, for leaks
using a soap solution.
10. Follow the lighting instructions located inside the
control compartment door.
4D. Removal of Gas Burners
1. Turn off the main line gas valve.
2. Unscrew the gas supply pipe from the gas valve.
3. Disconnect all wires to the gas valve.
4. Remove the two screws securing the anti-rotation
bracket to the inner panel, and the three screws
attaching the manifold bracket. Slide the burner
tray out of the heater (see Fig. 29).
Figure 28. Gas Valve Removal
NOTE: Due to sharp edges on the metal burner, wear
protective gloves for the next steps.
5. Grasp the burner firmly, and push it away from
the manifold until it is clear of the orifice. Slide it
out of the burner tray (see Fig. 29).
6. To replace the burner, insert the rear into the slot
at the rear of the burner tray, line it up with the
proper orifice and snap it into position.
7. Reinstall the burner tray by sliding it back into the
heater and securing it with the two brackets.
8. Connect the gas pipe, turn on the gas supply and
check the system for leaks with a soap solution.
9. Reconnect the electrical wires to the gas valve
according to the schematic on page 6.
NOTE: If the burner being removed is the one with
the pilot attached, follow these additional procedures
starting at Step 6.
1. Disconnect the pilot gas tube from the gas valve.
2. Detach the pilot burner assembly from the burner
bracket and remove the burner according to the
instructions in Step 6.
3. Install the pilot burner assembly on the new
burner. Install it in the burner tray and reconnect
the pilot gas tube to the pilot assembly and gas
valve.

4E. Periodic Inspection of Heat 1. Dry the heat exchanger completely.
Exchanger Water Passages
Scale can accumulate inside the heat exchanger
tubes. The easiest method of determining the degree
of scale buildup is to periodically inspect the tubes.
Perform this inspection after sixty days of operation,
and after 120 days of operation. This will establish a
regular inspection routine. |
An inspection and cleaning of the complete heat | |
exchanger can only be accomplished by removing it (À | |
from the heater (see Fig. 34 and the instructions in
Section 5). | | >
2. Remove the front and rear headers from the tube
assembly.
3. Remove the tube baffles.
4F. Cleaning the Heat Exchanger
A CAUTION
Black carbon soot buildup on a dirty heat
exchanger can be ignited by a random spark or
flame. To prevent this happening, dampen the
soot deposits with a wet brush or fine water
spray before servicing the heat exchanger. A
light accumulation of soot or corrosion on the
outside of the tubes can be easily removed with
a wire brush after the heat baffles are removed.
Follow the instructions in Section 2 to remove
the heat exchanger.
