Location
This water heater should be located close enough to the outside
wall so that it is within the venting requirements listed in these
installation instructions and as close as possible to the main
use of hot water. This location must not be subject to freez-
ing temperatures. The water heater should be positioned so
that there is easy access to the burner, gas control valve, and
drain valve. Where a floor drain is not adjacent to the water
heater, a suitable drain pan must be installed under the water
heater (see Figure 7). This drain pan should be at least four
(4) inches (10.2 cm) larger than the diameter of the water
heater and at least one (1) inch (2.5 cm) deep, providing
access to the drain valve. This pan must be piped to a suitable
drain to prevent damage to property in the event of a water
leak from the piping, the relief valve, or the water heater.
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.
This water heater is approved for installation on either a com-
bustible or non-combustible floor. However, should this water
heater be installed directly on carpeting, such 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.
Minimum Clearances
The minimum clearances from combustible material for this
water heater are: Two (2) inches (5.1 cm) from the sides and
rear, four (4) inches (10.2 cm) from the front, and eighteen
(18) inches (45.7 cm) from the top (see Figure 1).

WARNING
CAUTION
AVERTISSEMENT
ATTENTION
When installing the venting system, make sure to follow
all local codes or, in the absence of local codes, the latest
edition of CAN/CSA B149.1, Natural Gas and Propane Gas
Installation Code, in Canada, and/or the latest edition of the
National Fuel Gas Code, ANSI Z223.1/NFPA54, in the United
States. NEVER operate the water heater unless it is proper-
ly ventilated to the outdoors and has adequate air supply for
proper operation. Failure to properly install the venting sys-
tem could result in property damage, personal injury, or death.
INSTALLATION INSTRUCTIONS
IMPORTANT
These instructions have been written as a guide for the proper installation and operation of your water heater, and the manufac-
turer of this water heater will not accept any liability where these instructions have not been followed. However, for your safety
and to avoid damage caused by improper installation, this water heater must be installed by an EnerCare Certified Licensed
Professional and meet all local codes or, in the absence of local codes, the latest edition of CAN/CSA B149.1, Natural Gas and
Propane Gas Installation Code, in Canada, and/or the latest edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54, in
the United States.
Before proceeding with the installation instructions:
1) Inspect the water heater and its component parts for possible damage. DO NOT install or attempt to repair any
damaged component parts. If you detect any damage, contact EnerCare Home Services at 1-866-554-5591.
2) Verify that the type of gas being supplied corresponds to that which is marked on the rating plate and gas control
valve of the water heater.

54
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 certi-
fied 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 inter-
mixed 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.
IMPORTANT
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.
This water can be vented using only one of the following options:
• Three (3) inch (7.6 cm) schedule 40 PVC or CPVC pipe and
fittings;
PolyPro
®
InnoFlue
®
• Three (3) inch (7.6 cm) polypropylene rigid pipe and fit-
tings from Centrotherm (Innoflue single wall vent system);

Before installing the vent piping, make sure that the vent sys-
tem layout has been properly planned. Make sure that the flue
baffle has been installed in the flue tube. If the baffle is not
present, immediately contact the dealer where the water heater
was purchased. NEVER operate the water heater without the
flue baffle installed. Verify that the location of the water heater
respects all clearances from combustible material, all venting
requirements (see Table 1), and that the vent terminations
will be installed as specified by all local codes or, in the absence
of local codes, the latest edition of CAN/CSA B149.1, Natural
Gas and Propane Installation Code, in Canada, and/or the latest
edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54, in
the United States (see Figure 3).
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 com-
mon 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.

AVERTISSEMENT
ATTENTION
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 down-
ward (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 terminat-
ing 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).
The air intake equivalent vent length must be equal to or less
than the exhaust equivalent vent length and the air intake ter-
mination elbow shall be equipped with a standard wire mesh
screen.
IMPORTANT
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.

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 larg-
er than the diameter of the vent pipe selected. The larger holes will
allow for final alignment with the water heater. Construct the vent

DANGER
WARNING
CAUTION
AVERTISSEMENT
ATTENTION
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 pro-
perty 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 conden-
sate from adversely affecting the mechanical components of
the water heater (draining back into the blower), a rubber adap-
tor 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 lay-
out 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” N.P.T. 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 discon-
nected, 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
DANGER
WARNING
CAUTION
AVERTISSEMENT
ATTENTION
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 EnerCare
Home Services at 1-866-554-5591 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.
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.
• Must not terminate less than six (6) inches (15 cm) and not
more than twelve (12) inches (30 cm) above the floor.
• 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 210oF (99oC)
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 cre-
ating a pressure build-up. This is a natural function and is one
of the reasons for installing a temperature and pressure-relief
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. Call EnerCare Home Services at 1-866-554-5591. If the
relief valve is not defective, the service call may be at the cost of
the consumer.
Filling the Water Heater
DANGER
WARNING
CAUTION
AVERTISSEMENT
ATTENTION
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 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.

WARNING
CAUTION
AVERTISSEMENT
ATTENTION
DO NOT attempt to use this water heater with any gas
other than the type of gas shown on the water heater rat-
ing plate. Failure to follow this instruction can result in
property damage, personal injury, or death.
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 edi-
tion 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 (sedi-
ment 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 sup-
ply 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.
DANGER
WARNING
CAUTION
AVERTISSEMENT

or explosion could occur resulting in property damage,
personal injury, or death.
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.
INSTALLATION INSTRUCTIONS

1312
INSTALLATION INSTRUCTIONS
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 indi-
cated on the water heater rating plate.
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 shut-off 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 sup-
ply manual shut-off valve must be closed. All testing must
be done according to CAN/CGA B149 in Canada and/or the
National Fuel Gas Code, ANSI Z223.1 in the United States
and local codes.

WARNING
CAUTION
AVERTISSEMENT
ATTENTION
A high altitude orifice MUST BE installed for water heat-
ers operating above 2,000 feet (610 m). Failure to follow
this instruction can result in property damage, personal

Wiring
DANGER
WARNING
CAUTION
AVERTISSEMENT
ATTENTION
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.
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).
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 par-
ticular, the following:
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.
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.
3) If this water heater is to be used for space heating, make
sure that all safety codes are respected. Pay special atten-
tion to safety valve pressure and expansion tanks.
4) Do not use toxic chemicals to clean the potable water
heating system.
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.
6) If the incoming water line to the heater is equipped with
a check valve, 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.
7) Before acquisition of a water heater for space heating appli-
cation, it is necessary to have the area of intended use
sized by an EnerCare 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.

Water Temperature Regulation
DANGER
WARNING
CAUTION
AVERTISSEMENT
ATTENTION
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 tem-
perature 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 hold-
ing down both the COOLER and HOTTER temper-
ature 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 but-
tons 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

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 reached the desired
setting HOLDING DOWN THE BUTTON WILL NOT
CONTINUE TO LOWER THE SETTING. The but-
ton must be pressed and released for each temperature
change desired.
To increase the temperature, press and
release the HOTTER button once. The temperature
indicators will now display the new temperature setting.
Press and release the HOTTER button until you have
reached the 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 docu-
ment, or call EnerCare Home Services at 1-866-554-5591.
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 fau-
cet with your hand before use. This will reduce the risk of
scalding-related injuries.
OPERATING INSTRUCTIONS

1716
The gas control valve pictured in this manual is equipped
with a single-use 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 replaced immediately replaced by
EnerCare.
DANGER
WARNING
CAUTION
AVERTISSEMENT
ATTENTION
Should overheating occur or the gas supply fail to shut
off, 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 call EnerCare
Home Services at 1-866-554-5591 and let them know your
situation.
Housekeeping
Keep the area around the water heater clean and free of dust,
lint, and dirt. It is the responsibility of the homeowner to do
so in order to prevent any malfunction that is not EnerCare’s
responsibility.
DANGER
WARNING
CAUTION
AVERTISSEMENT
ATTENTION
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.
Flammable Vapour Sensor
This water heater is equipped with a flammable vapour sen-
sor (FV) that will shut it down in the event of a flammable
vapour incident. It is a safety feature that may prevent prop-
erty damage, personal injury, or death.
The FV sensor is located on the front left bottom of the exte-
rior 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 flam-
mable vapours before they enter the combustion chamber
and ignite. If the FV sensor detects the presence of flam-
mable 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.
After a flammable vapour incident has occurred and the flam-
mable 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. An EnerCare 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 combus-
tion chamber, the water heater may need to be replaced. The
EnerCare 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 con-
dense. 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.
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.
Due to the high-efficiency rating of this gas-fired water
heater, it may produce more condensation than older mod-
els. 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.
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 indi-
cates proper gas combustion. A yellow tipped flame indicates
poor combustion. If so, with a vacuum cleaner, remove any
dust, lint, and dirt accumulation on or around the combus-
tion chamber. If the poor combustion persists and there is
no lint around the water heater call EnerCare Home Services
at 1-866-554-5591. This service call may be at the expenses
of the consumer if lint is blocking the flame arrestor plate.
Water Heater Tank
You may choose to drain the tank at your convenience in very
hard water conditions.
GENERAL MAINTENANCE

18
Temperature and Pressure-Relief Valve
On a regular basis, visually inspect the valve for any leakage, if
so call EnerCare Home Services at 1-866-554-5591.
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 dam-
aged, it must be replaced by EnerCare Home Services at
1-866-554-5591.
Anodes
DANGER
WARNING
CAUTION
AVERTISSEMENT
ATTENTION
The cap covering each anode on top of the water heater
MUST BE put back in place after servicing the anodes.
This water heater is equipped with two anodes that are
designed to prolong the life of the glass-lined tank. The
anodes are slowly consumed, protecting the glass-lined tank
from corrosion. If you get rotten egg smell, call EnerCare
Home Services at 1-866-554-5591 that may have a solution
to your water condition problem (See the explanation of rot-
ten eggs below).
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 anodes are consumed
more rapidly.
Please advise EnerCare that you operate a water softener so
they can take the proper precaution.
In certain water conditions, the anodes will react with the
water, producing discoloured or smelly water. The most
common complaint is hot water that smells like rotten eggs.
This phenomenon is the result of the reaction between the
anodes 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 anodes
to a type more suitable for these conditions (aluminum
anodes) and by chlorinating the water heater and plumbing
system. If the problem persists, special filtration equipment
may be required. Under no circumstances are the anodes
to be removed from the water heater on a permanent basis.
Removal of the anodes will lead to premature fail-
ure of the water heater and void the warranty.
This is not an EnerCare issue but a consumer issue in the
water supply and the consumer is responsible for any appa-
ratus needed to remove the rotten egg smell.
DANGER
WARNING
CAUTION
AVERTISSEMENT
ATTENTION
Hydrogen gas can be produced in a hot water sys-
tem 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 com-
pletely full of water and that the cold water supply manual
shut-off valve is open, before lighting the burner.
