Venting
Sooner or later, all water heaters leak. The
manufacturer, based on national building codes,
has given the necessary instructions to prevent
damage to the building. Under no circumstances
is the manufacturer to be held liable for any water
damage, in connection with this water heater.
DANGER
When installing the venting system, make sure to follow
all local codes or, in the absence of local codes, CAN/CSA
B149.1, Natural Gas and Propane Gas Installation Code, in
Canada and/or the National Fuel Gas Code, ANSI Z223.1/
NFPA 54, in the United States. NEVER operate the water
heater unless it is properly ventilated to the outdoors and has
adequate air supply for proper operation. Failure to properly
install the venting system could result in property damage,
personal injury, or death.
This water heater is approved for installation on either a combustible or non-combustible floor. However, should this water
heater be installed directly on carpeting, the carpeting must be
protected by a wood or metal panel beneath the water heater.
This panel must extend at least three (3) inches (7.6 cm)
beyond the width and depth of the water heater. Should the
water heater be installed in an alcove or closet, the entire floor
area must be covered by the panel.

INSTALLATION INSTRUCTIONS
edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54,
in the United States (see Figure 3).
I MPORTANT
According to the CAN/CSA-B149, Natural Gas and Propane
Installation Code, plastic vent systems installed in Canada
must be certified to the STANDARD FOR TYPE BH GAS
VENTING SYSTEMS, ULC S636. Components of the certified vent system must not be interchanged with other vent
systems or unlisted pipe/fittings. Plastic components and
specified primers and glues of the certified vent system must
be from a single vent system manufacturer and not intermixed with other vent system manufacturer’s vent system
parts unless those are certified to be used with this system.
Plastic vent systems shall also be installed such that the first
three (3) feet (91 cm) of pipe from the water heater outlet
are readily accessible for visual inspection. The air intake
system does not have to meet the requirement of ULC S636,
so regular schedule 40 PVC or CPVC pipes and fittings can be
used to convey the flow of fresh air to the water heater.
This water heater must be vented directly to the outdoors, either
horizontally through the wall or vertically through the roof. The
venting must not be attached to an existing chimney, or in common with any other appliance, and must not be insulated. If
possible, locate the water heater so that the venting length and
number of elbows are kept to the minimum necessary to reach
the outside.
Venting Connection to the water heater
PVC PIPE:
A vent system adaptor should be installed when using PVC
pipes for venting this water heater (see Figure 2). The vent
system adaptor supplied with the water heater is made of IPEX
parts. If another manufacturer of pipe is used to build the vent
system, the vent system adaptor must be made from parts of
that same manufacturer.
This water heater is a power direct vent gas water heater that
draws all of its combustion air from outside of the building
and vents all of its combustion gases directly outside of the
building.
CPVC PIPE:
The CPVC pipe must be inserted directly into the rubber transition fitting on the outlet of the blower assembly.
POLYPROPYLENE PIPE FROM CENTROTHERM
(Innoflue single wall vent system): InnoFlue

INSTALLATION INSTRUCTIONS
Through-the-Wall Venting Installation
WARNING
When installing the vent piping make sure that the vent
terminal is NEVER installed below the air intake terminal.
The air intake terminal must always face downward. Failure
to follow this instruction could result in property damage,
personal injury, or death.
Two (2) vent terminal options are available to vent this water
heater. The first is a standard 90-degree elbow facing downward (see Figure 6a) and the second is the concentric vent
termination kit (see Figure 6b).
Cut or drill two (2) holes through the exterior wall, slightly larger
than the diameter of the vent pipe selected. The larger holes
will allow for final alignment with the water heater. Extend a
section of pipe through each hole to the outside and attach the
terminating elbow to the exterior end of each pipe. The vent and
air intake terminals must be at least eight (8) inches (20.3 cm)
apart and the vent terminal must NEVER be installed below
the air intake terminal for any reason (see Figure 6a). The
air intake terminal and the vent terminal must terminate on the
same exterior wall (same atmospheric pressure zone).
I M P ORTANT
The air intake equivalent vent length must be equal to or less than
the exhaust equivalent vent length and the air intake termination elbow shall be equipped with a standard wire mesh screen.
Connect and secure all piping and elbows from the power venter
to the wall. When the installation is completed, the vent and air
intake terminals must be at two (2) inches (5.1 cm) from the
exterior surface of the wall (see Figure 2). Do not extend vent
or air intake piping past this length. Make sure that all piping is
properly supported. If the venting will pass through an enclosed
area, make sure to leave at least one (1) inch (2.5 cm) clearance
around the piping for air circulation.
FOR PVC AND CPVC PIPING:
Make sure that all horizontal runs have a minimum rise
of 1/4 inch per foot (21 mm/m) of run (see Figure 7).
Horizontal runs of vent pipe must be supported every three
(3) feet (91 cm).
FOR POLYPROPYLENE PIPE FROM CENTROTHERM
(Innoflue single wall vent system): InnoFlue
Make sure that all horizontal runs have a minimum rise of
5/8 inch per foot (56 mm/m) of run. Follow instruction of the
vent pipe manufacturer for proper vent support.

Concentric Vent Termination Kit Installation
A three (3) inch (7.6 cm) Concentric Vent Termination Kit (IPEX
model 196006) may be used with a three (3) inch (7.6 cm)
restrictor screen for side wall termination installations. Using
this Concentric Vent Termination Kit will reduce the maximum
allowable equivalent vent pipe length for both air intake and
exhaust systems (see Table 1). Figure 6b illustrates the
Concentric Vent Termination Kit for side wall installation. See
manufacturer’s instructions for complete installation details.
Through-the-Roof Venting Installation
Cut or drill two (2) holes through the roof and ceiling, slightly
larger than the diameter of the vent pipe selected. The larger holes
will allow for final alignment with the water heater. Construct the
vent terminal assembly. Extend a section of pipe through each
hole in the roof to the outside and attach the terminal assembly
to the exterior end of each pipe. The vent and air intake terminals
must be at least eight (8) inches (20.3 cm) apart and the vent
terminal must NEVER be installed below the air intake terminal for any reason (see Figure 2). The air intake terminal and
the vent terminal must penetrate the same side of roof and be
oriented facing downward in the same direction. Connect and
secure all piping and elbows from the power venter to the roof.
When the installation is completed, the air intake terminal must
be at a minimum of eighteen (18) inches (45.7 cm) from the
exterior surface of the roof or anticipated snow accumulation
level (see Figure 2). The vertical terminations should be sealed
with a plumbing roof boot or equivalent flashing. Make sure that
all piping is properly supported. If the venting will pass through
an enclosed area, make sure to leave at least one (1) inch
(2.5 cm) clearance around the piping for air circulation.

5) Apply a liberal coat of cement to the vent pipe, leaving no
voids.
6) QUICKLY assemble parts while cement is fluid! If you
wait too long, re-coat pipe/fitting.
WARNING
7) Push the vent pipe completely into the coupling,
turning as it goes until it bottoms out.
In freezing weather, check for snow accumulation around
the water heater vent and air intake terminals where they
pass through the outside wall. The open ends of the terminals must be installed at least twelve (12) inches (30
cm) above the highest anticipated snowfall to prevent
blockage by snow.
8) Hold pipe and fitting together for thirty (30) seconds. Then
carefully clean off any excess material with a cloth. Allow connections a sufficient time to cure before disturbing.
9) Remember that vent pipes must be adequately and
securely suppported.

gasket at the end of the termination elbow and insert the
restrictor screen. Push firmly the screen into the elbow pass
the gasket groove. Put the gasket back into place.
Figure 8
The air intake screen can be removed on the air intake
terminal in cold environment. Thus, this may make the air
intake susceptible to debris build-up in the air intake pipe.
A second screen is installed in the rubber adaptor on the air
inlet at the back of the water heater to prevent debris from
entering the water heater. This screen can be accessed for
cleaning by removing the pipe on top of the rubber adaptor.
If the air intake screen is removed to prevent freezing, it is
recommended that the air inlet screen be installed during
the spring.
WARNING
When the installation is complete, visually inspect the
venting system to make sure that all joints are properly
connected and all instructions have been followed. Failure
to properly install the venting system could result in property damage, personal injury, or death.
Condensation in the Venting System
In some installations, condensation will form in the horizontal
runs of vent piping. In order to effectively control the condensate from adversely affecting the mechanical components
of the water heater (draining back into the blower), a rubber
adaptor with a drain outlet is mounted directly on the blower
vent outlet. A plastic tube can be attached to this outlet to drain
any condensate that has accumulated, away from the water
heater. Make sure that the condensate removal tube flows to a
suitable free-flowing drain.
Water Piping
Refer to Figure 7 for a typical installation. Use of this layout should provide a trouble-free installation for the life of
the water heater. Before making the plumbing connections,
locate the COLD water inlet and the HOT water outlet.
These fittings are both 3/4” NPT male thread. Make sure
that the dip-tube is installed in the cold water inlet. Install
a shut-off valve close to the water heater in the cold water
line. It is recommended that unions be installed in the cold
and hot water lines so that the water heater can be easily
disconnected, if servicing is required.
When assembling the hot and cold piping, use a good
food grade of pipe joint compound, and ensure all fittings are tight. DO NOT APPLY HEAT TO THESE
FITTINGS when making sweat connections to the water
heater. Sweat tubing to threaded adaptors before connecting to the water heater. IT IS IMPERATIVE THAT NO
HEAT BE APPLIED to the cold water inlet, as it contains
a non-metallic dip-tube. This will result in premature
failure of the fittings, which is not covered by the
warranty.
Temperature and Pressure-Relief Valve
WARNING
DO NOT plug the temperature and pressure-relief valve
or its discharge line. DO NOT remove the relief valve.
Make sure the relief valve is properly sized for the water
heater. If the relief valve continuously discharges water, call a
qualified service technician to correct the problem. Failure
to follow these instructions can result in property damage,
personal injury, or death.
To protect from excessive pressure and/or temperature, the
manufacturer has installed a temperature and pressure-relief
valve that meets the requirements of the Standard for Relief
Valves and Automatic Gas Shut-Off Devices for Hot Water
Supply Systems, CSA 4.4, in Canada, and ANSI Z21.22, in the
United States. This relief valve has a maximum set pressure
that does not exceed the hydrostatic working pressure of the
water heater (150 psi = 1,035 kPa) and a BTU/hr rating equal
to or greater than the input rating, as shown on the water
heater rating plate. It should never be plugged or removed
from the opening marked for it on the water heater.

INSTALLATION INSTRUCTIONS
If this relief valve should need to be replaced, use only a new
temperature and pressure-relief valve. NEVER install an old
or existing relief valve, as it may be damaged or inadequate
for the working requirements of the new water heater. This
new relief valve must meet all local codes or, at a minimum,
the requirements listed above. NEVER install any other type
of valve between the relief valve and the water heater.
A discharge line must be installed into the relief valve. The
discharge line:
• Must not be smaller than the outlet pipe size of the relief
valve.
in use. NEVER operate the water heater with the cold
water supply manual shut-off valve closed.
3) To make sure the water heater is completely full of water,
open all of the hot water faucets in the house to let the air
out of the water heater and plumbing system. Leave the
faucets open until a constant flow of water is obtained.
4) Check all of the plumbing connections to make sure
there are no leaks.
Gas Connections
WARNING
• Must not terminate less than six (6) inches (15 cm) and
not more than twelve (12) inches (30 cm) above floor.
DO NOT attempt to use this water heater with any gas
other than the type of gas shown on the water heater rating plate. Failure to follow this instruction can result in
property damage, personal injury, or death.
• Must not be restricted in any way. Do not thread, cap, or
in any way restrict the end of this outlet.
• Must be of a material capable of withstanding 195oF
(91oC) without distortion.
• Must be installed to allow complete drainage of the relief
valve and discharge line.
• Must terminate at an adequate free-flowing drain.
Pressure Build-up in a Water System
When the water heater operates, the heated water expands
creating a pressure build-up. This is a natural function and is
one of the reasons for installing a temperature and pressurerelief valve. If the cold water supply line has a built-in water
meter, check valve, or pressure-reducing valve, a suitable
expansion tank must be installed to prevent pressure build-up
or water hammer effect. Otherwise, the warranty is void (see
Figure 7). An indication of pressure build-up is frequent
discharges of water from the relief valve. If the relief valve
discharges water on a continuous basis, it may indicate a
malfunction of the relief valve, and a qualified service technician
must be called to have the system checked, and the problem
corrected.
The gas piping must be installed as indicated in Figure 7.
For the correct size of piping for this water heater, consult
the latest edition of CAN/CSA B149.1, National Gas and
Propane Installation Codes, in Canada, and/or the latest
edition of the National Fuel Gas Code, ANSI Z223.1/NFPA
54, in the United States. Only new piping with cleanly
cut threads may be used, together with a suitable sealing
compound that is approved for natural and propane gases.
It is mandatory that a readily accessible manual shut-off
valve be installed in the gas supply line. The gas supply
manual shut-off valve must be close to the water heater.
A drip leg (sediment trap) must be installed in the gas line
ahead of the gas control valve to prevent dirt from entering it. A union must be installed between the gas control
valve and the gas supply manual shut-off valve for easy
maintenance of the water heater.
The water heater and its gas connection must
be leak tested before placing the appliance into operation.
WARNING
NEVER use an open flame to test for gas leaks. A fire
or explosion could occur resulting in property damage,
personal injury, or death.
Filling the Water Heater
WARNING
NEVER operate the water heater unless it is completely
filled with water. Failure to follow this instruction
can result in premature failure of the water
heater that is not covered by the warranty.
Check that all of the water piping connections have been
made. To fill the water heater:
1) Make sure that the water heater drain valve is closed by
inserting a flat head screwdriver into the slot on the head
of the drain valve and turning the knob clockwise
.
2) Open the cold water supply manual shut-off valve. This
valve must remain open, as long as the water heater is
To leak test the system:
1) Turn on the manual gas shut-off valve near the water
heater.
2) Use a soapy water solution to test all connections and
fittings for leaks. Bubbles indicate a gas leak.
3) Correct all leaks.
Make sure that the inlet pressure to the water heater does not
exceed 0.5 PSI (3.5 kPa) for both natural and propane gases.
Pressures in excess of 0.5 PSI (3.5 kPa) can damage the gas
control valve, resulting in a fire or explosion from leaking gas.
For purposes of adjustment, the minimum inlet pressure is
indicated on the water heater rating plate.
12
INSTALLATION INSTRUCTIONS
If any pressure testing of the gas line is undertaken at test pressures in excess of 0.5 PSI (3.5 kPa),
the water heater and its gas supply manual shutoff valve must be disconnected from the gas supply
piping system, and the end of the pipe sealed with a female
cap. If the testing is to be undertaken at a test pressure less
than 0.5 PSI (3.5 kPa), the gas supply manual shut-off valve
must be closed.
Installation Instructions for Water Heaters
Approved for Combination Space Heating and
Potable Water Heating (see Figure 10)
A water heater cannot be used for space heating only. When
using a water heater for combination space and potable
water heating, the instructions provided in this manual and
with the air-handling unit must be respected and, in particular, the following:
WARNING
1) All piping and components that are used in the
system must be of a nonferrous type suitable for potable
water. This also applies to any sealant used.
U.L. and CSA recognized fuel gas and Carbon Monoxide
(Co) detectors are recommended in all applications and
should be installed using the manufacturer’s instructions
and local codes, rules, or regulations.
2) When used as a dual purpose water heater, it must not
be connected to any system that has been previously
used for non-potable water heating. This includes any piping because, in all probability, existing piping would have
been, in the past, treated with chemicals for cleaning or
sealing the system.
WARNING
A high altitude orifice MUST BE installed for water heaters
operating above 2,000 feet (610 m). Failure to follow this
instruction can result in property damage, personal injury,
or death.
3) If this water heater is to be used for space heating, make
sure that all safety codes are respected. Pay special
attention to safety valve pressure and expansion tanks.
4) Do not use toxic chemicals to clean the potable water
heating system.
Wiring
WARNING
5) Where water temperature in excess of 140oF (60oC) is
required for a space heating application, a mixing valve
must be installed in the potable side of the system. This
will temper the water and reduce the risk of scalding.
This water heater uses an external electrical source for
power. It must be electrically grounded in accordance
with all local codes or, in the absence of local codes, the
latest edition of CSA C22.1 Canadian Electrical Code, in
Canada, and/or the latest edition of the National Electrical
Code, ANSI/NFPA 70, in the United States. Failure to
properly ground this water heater can result in property
damage, personal injury, or death.
6) If the incoming water line to the heater is equipped with
a check valve, backflow preventer, water meter, or pressure-reducing valve, an expansion tank must be installed
in the system. This will prevent weeping from the water
heater relief valve and premature failure of the heater
due to expansion of the water during the heating cycle.
Before lighting your water heater, check that all of the wires
have been installed correctly (see Figure 9). Make sure that
none of the wires are grounded, have split, or are broken.
Verify that all wiring connections are properly secured, as
there is a possibility that they have become loose during
transport. If any of the original wiring needs replacing, use
only 18AWG-type or greater wire that is approved for 221oF
(105oC).
7) Before acquisition of a water heater for space heating
application, it is necessary to have the area of intended
use sized by a qualified technician. This will ensure that
an adequate water heating capacity will be available for
both heating and potable water supply, and that the
application will meet all local codes and public utility
requirements.
Note: It is good practice to oversize the water heater, to
ensure that all of the potential hot water requirements
are available.

OPERATING INSTRUCTIONS
Lighting the Water Heater
WARNING
DO NOT light this water heater if:
• It is not full of water.
• The gas supplied does not match the type listed on
the rating plate.
• Gasoline or other flammable vapours and liquids
have been stored in the vicinity of the water heater.
Failure to follow these instructions can result in property
damage, personal injury, or death.
Before lighting or re-lighting your water
heater, make sure that you have read and
understood all of the instructions and warnings in this manual and on your water heater. If you have any questions about lighting
your water heater, immediately contact a
qualified installer, service agency, or the gas supplier.
Lighting Instructions
16
OPERATING INSTRUCTIONS
Water Temperature Regulation
WARNING
The higher the temperature setting, the greater the risk of
scalding. Hot water can cause third degree burns in under
one (1) second at 160oF (71oC), in five (5) seconds at
140oF (60oC), and in thirty (30) seconds at 130oF (54oC). In
households where there are children, physically challenged
individuals, or seniors, mixing valves for point of use are
necessary as means of reducing the scalding potential of
hot water.
When the water heater is plugged in for the first time, the
gas control valve will start to heat the water to the factory
adjusted temperature. To avoid any unintentional changes
in the water temperature settings, the gas control valve has
a tamper-resistant feature included for changing the temperature setting. If you want to change this setting for either
cooler or warmer water, the following steps are necessary:
1. “Wake up” the temperature indicators by holding down
both the COOLER and HOTTER temperature adjustment buttons at the same time for one (1) second (see
Lighting Instructions). One or two of the temperature
indicators will light up. These indicators will only remain
on for thirty (30) seconds, if no further buttons are
pressed. After thirty (30) seconds, the control will go
back to “Sleep” mode, and both buttons will again have to
be pressed to see the water temperature setting. Release
both of the temperature adjustment buttons. See Figure
11 for an explanation of what each of the temperature indicators mean.
To decrease the temperature, press and release
the COOLER button once. The temperature indicators will now display the new temperature setting.
Press and release the COOLER button until you have

desired setting. HOLDING DOWN THE BUTTON
WILL NOT CONTINUE TO RAISE THE SETTING.
The button must be pressed and released for each temperature change desired.
To maximize the efficiency of this water heater and reduce
the risk of scalding, it is recommended that the gas control
valve be set at the setting below the large triangle (« »),
which represents approximately 120°F (49°C).
2. When you have completed setting the control, wait thirty
(30) seconds to see that the temperature indicators go
off and the control enters “Sleep” mode. ALL OF THE
TEMPERATURE INDICATORS WILL BE OFF
DURING NORMAL OPERATION. If at any time you
see the indicators on, there may be a problem with the
water heater and you should consult the Troubleshooting
Guide of this document, or contact a trained service professional.
When hot water is drawn from the tank in frequent
short bursts, a condition known as “stacking” is created.
“Stacking” is the result of increased cycling of the burner and
can produce very hot water temperatures at the hot water outlet. Always remember to check the hot water coming out of
any faucet with your hand before use. This will reduce the
risk of scalding-related injuries.

OPERATING INSTRUCTIONS
The gas control valve pictured in this manual is equipped
with a resettable type automatic high temperature cut-off.
Should the temperature of the water exceed 195oF (91oC),
the high temperature cut-off will automatically shut off the
gas supply to the water heater. If this situation occurs, the
gas control valve must be reset by a qualified service technician.
WARNING
Should overheating occur or the gas supply fail to shutoff, close the gas supply manual shut-off valve. Failure
to follow this instruction can result in property damage,
personal injury, or death.
Out of Fuel
If your water heater should run out of gas, proceed as follows:
1) Toggle the “ON/OFF” switch located on the gas control
to the “OFF” position.
2) Unplug the power cord from the wall socket.
3) Close the gas supply manual shut-off valve.
4) Once the gas supply has been re-established, proceed to
the Lighting Instructions.
Housekeeping
Keep the area around the water heater clean and free of dust,
lint, and dirt. Make sure that all of the minimum clearances to
combustible materials are being maintained.
After a flammable vapour incident has occurred and the
flammable vapours have dissipated, the FV sensor is
designed to automatically reset itself. The Intelli-Vent® gas
control however, will have gone into lock-out mode and will
need to be manually reset. A qualified service technician
must be called to determine if flammable vapours entered
the combustion chamber and ignited. In most instances,
there will not have been ignition of flammable vapours
inside the combustion chamber because the FV sensor will
have detected these vapours and shut down the water heater. In this case, the Intelli-Vent® gas control can be reset
and the water heater may resume normal operation. On the
other hand, if the flammable vapours ignited inside the combustion chamber, the water heater may need to be replaced.
The technician will be able to determine whether or not the
water heater needs to be replaced based on the amount of
flammable vapours that entered the combustion chamber
and the damage to the water heater from the resulting fire.
Condensation
As moisture from the products of combustion comes into
contact with the cold surface of the inner tank, it may condense. This situation will usually occur:
1) When the water heater is filled with cold water for the
first time.
2) If the water heater has been undersized.
WARNING
3) When large amounts of hot water are drawn from the
water heater in a short period of time, and the refill water
is very cold.
DO NOT store or use gasoline or other flammable
vapours and liquids around the water heater.
DO NOT put or store any objects on the top of the water
heater.
Failure to follow these instructions can result in property
damage, personal injury, or death.
Due to the high-efficiency rating of this gas-fired water
heater, it may produce more condensation than older models. Condensation forming on the flue tube will drop on
the burner making a “sizzling” sound. This condition is not
uncommon and must never be misinterpreted as a leaking
tank. It will disappear once the water becomes heated.
Flammable Vapour Sensor
This water heater is equipped with a flammable vapour sensor (FV) that will shut it down in the event of a flammable
vapour incident. It is a safety feature that may prevent property damage, personal injury, or death.
Because of the large amounts of water that can
condense, it is very important that a drain pan be installed under
the water heater (refer to Figure 7). Under no circumstances is the manufacturer to be held liable for any
water damage, in connection with this water heater.
If the problem does not go away and water continues to drip
after the water heater has heated up, check all of the plumbing
connections to make sure they are not leaking.
The FV sensor is located on the front left bottom of the exterior casing of the water heater. The FV sensor is protected
from shock and contaminants by a robust plastic cover. The
function of the FV sensor is to detect the presence of flammable vapours before they enter the combustion chamber
and ignite. If the FV sensor detects the presence of flammable vapours while the water heater is operating, the gas
control will switch to lock-out mode and the water heater
will shut down. If the water heater is not operating when the
flammable vapours are detected, the control will switch to
lock-out mode and prevent the water heater from lighting.
18
GENERAL MAINTENANCE
Burner Ignitor Assembly
Every three (3) months, check the burner and flame ignitor
assembly. Remove the outer access door and look through
the sight glass to examine the flames. A soft blue flame
indicates proper gas combustion. A yellow tipped flame
indicates poor combustion. With a vacuum cleaner, remove
any dust, lint, and dirt accumulation on or around the combustion chamber.
Water Heater Tank
Drain a pail of water through the drain valve at least once a
year. This will remove excess sediment from the bottom of the
tank. This sediment, if allowed to accumulate, will reduce the
efficiency and the life of the tank.
Temperature and Pressure-Relief Valve
Manually operate the temperature and pressure-relief valve at
least once a year, standing clear of the outlet to avoid being
burned. Lift and release the operating lever on the valve to
make it operate freely. If, after manually operating the valve,
it fails to completely reset itself and continues to discharge
water, replace it with a new one.
Venting System Inspection
The venting system must be thoroughly inspected once a
year. Check the venting system to make sure that all of the
connections are securely fastened, and that all of the joints
are properly sealed. If any part of the venting system is damaged, it must be replaced by a qualified service technician.
Anode
WARNING
The cap covering the anode on top of the water heater
MUST BE put back in place after servicing the anode.
This water heater is equipped with an anode that is designed
to prolong the life of the glass-lined tank. The anode is
slowly consumed, protecting the glass-lined tank from corrosion. The anode should be checked every two (2) years. If
more than half of the anode has been consumed, it should
be replaced. Instructions on how to change the anode can
be obtained from the manufacturer.
The life expectancy of the water heater is reduced where a
water softener is introduced to fight hard water, because the
sodium salts added by a softener make this water extremely
conductive. In these conditions, the anode is consumed
more rapidly and should be verified every year.
In certain water conditions, the anode will react with the
water, producing discoloured or smelly water. The most
common observation is hot water that smells like rotten eggs.
This phenomenon is the result of the reaction between the
anode and hydrogen sulfide gas dissolved in the water, which
occurs frequently in well systems. This problem can usually be
eliminated or reduced by changing the anode to a type more
19
suitable for these conditions (aluminum anode) and by chlorinating the water heater and plumbing system. If the problem
persists, special filtration equipment may be required. Under
no circumstances is the anode to be removed from the water
heater on a permanent basis. Removal of the anode will
lead to premature failure of the water heater and
void the warranty.
WARNING
Hydrogen gas can be produced in a hot water system that
has not been used for a long period of time (generally two [2]
weeks or more). HYDROGEN GAS IS EXTREMELY
FLAMMABLE. It is highly recommended to open the hot
water faucet in the kitchen for several minutes before you use
any electrical appliances connected to the hot water system,
such as a dishwasher or washing machine. If hydrogen gas is
present, there will be an unusual sound, such as air escaping
through the pipe, as the hot water faucet is opened. DO NOT
smoke or introduce an open flame near the faucet when it is
opened.
Draining the Water Heater
To completely drain the water heater:
1) Toggle the “ON/OFF” switch located on the gas control
to the “OFF” position.
2) Unplug the power cord from the wall socket.
3) Close the gas supply manual shut-off valve.
4) Close the cold water supply manual shut-off valve.
5) Connect one end of a garden hose to the water heater drain
valve and put the other next to a free-flowing drain.
6) Open the drain valve by inserting a flat-head screwdriver
into the slot on the head of the drain valve and turn the
knob counterclockwise
.
7) Open a hot water faucet to allow air into the system.
Vacation
If you are planning a vacation or other prolonged absence,
it is highly recommended to shut-off the gas supply and
the cold water supply to the water heater. This will save
energy, protect against property damage in the event the
water heater leaks, and prevent the build-up of hydrogen
gas. If the water heater and piping are exposed to freezing
temperatures, they should both be drained.
Remember to check the water heater thoroughly after it has
been shut-off for an extended period of time before putting
it back in operation. Make sure that the water heater is completely full of water, and that the cold water supply manual
shut-off valve is open, before lighting the burner.
