Consumer Responsibilities
This manual has been prepared to acquaint you with the
installation, operation and maintenance of your gas fired
water heater and provide important safety information in
these areas. It is your responsibility to ensure that your
water heater is properly installed and cared for.
FAILURE TO FOLLOW THE INSTRUCTIONS IN THIS
MANUAL MAY RESULT IN SERIOUS BODILY INJURY
AND/OR PROPERTY DAMAGE. THOROUGHLY READ
AND UNDERSTAND ALL INSTRUCTIONS BEFORE YOU
ATTEMPT TO INSTALL, OPERATE OR MAINTAIN THIS
HEATER.
Installation and service requires trade knowledge in the
areas of plumbing, electricity, venting, air supply and gas
supply. If you lack these skills or have difficulty understanding these instructions, you should not proceed. Enlist the
help of a qualified service technician to install this water
heater.
Examples of qualified service technicians include those
trained in the plumbing and heating industry, local gas utility
personnel or an authorized service person.
– 3 –
Do not discard this manual. You or future users of this water
heater will need it for reference.
II) SAFETY
This water heater is design-certified by CSA International as
a direct vented water heater.
In addition to the installation instructions found in this manual, the water heater must be installed in accordance with
all local and provincial or state codes or, in the absence of
such, with the latest editions of the following specifications.
“Natural Gas and Propane Installation Code” CSAB149.1 and “Canadian Electrical Code (CAN/CSA C22.1),
Part I” available from:
Canadian Standards Association,
5060 Spectrum Way,
Mississauga, Ontario, Canada
L4W 5N6
Check your phone listings for the local authorities having
jurisdiction over your installation.
Safety Warning (Flammable Vapours)
Safety Warning (Carbon Monoxide)
WARNING
FLAMMABLES
FIRE AND EXPLOSION HAZARD
Can result in serious injury or death
Do not store or use gasoline or other flammable vapours and liquids
in the vicinity of this or any other appliance. Storage of or use of gasoline
or other flammable vapours or liquids in the vicinity of this or any other
appliance can result in serious injury or death.
There is a risk of property damage, personal injury or death
from the by-products of combustion (e.g., flue gases), in
using fuel-burning appliances such as water heaters. Areas
that may not be suitable for water heater installation include
those where flammable liquids, gasoline, solvents, adhesives etc. are stored, or where engine-driven equipment or
vehicles are stored, operated or repaired. These, and similar
products, should not be stored or used near the water heater
or air intake. Due to the nature of air movement, flammable
vapours can be carried some distance from the point of
storage. The gas-fired water heater igniter or burner flame
can ignite these vapours causing a flashback, fire or explosion, which may result in severe property damage, serious
personal injury or death. If flammable liquids or vapours
have spilled or leaked in the area of the water heater, leave
the area immediately and call the fire department from a
neighbor’s home. Do not attempt to clean the spill until all
ignition sources have been extinguished.
Safety Warning (Scalding)
Flammable Vapours
DANGER
DANGER
Carbon Monoxide Warning
• Follow all vent system requirements by
the local authorities having jurisdiction
over your installation.
• Failure to do so can result in death, explosion or carbon monoxide poisoning.
Relief Valve Requirements (T&P)
All water heaters must be fitted with a proper temperature
and pressure relief valve. These valves must be certified
as meeting the requirements of the “Standard For Relief
Valves For Hot Water Supply Systems, ANSI Z21.22/CSA
4.4”.
If this water heater has been exposed to flooding, freezing,
fire or any unusual condition, do not put it into operation until
it has been inspected and approved by a qualified service
technician.
THESE CONDITIONS CAN RESULT IN UNSEEN
INTERNAL DAMAGE and are not subject to warranty cov-
erage.
CAUTION
Hydrogen gas can be produced in a hot water system
served by this heater that has not been used for a
long period of time (generally two (2) weeks or more).
Hydrogen gas is extremely flammable and can ignite
when exposed to a spark or flame. To reduce the risk
of injury under these conditions, it is recommended that
the hot water faucet be opened for several minutes at the
kitchen sink before using any electrical appliance connected to the hot water system. Use caution in opening
faucets. If hydrogen is present, there will probably be an
unusual sound such as air escaping through the pipe as
the water begins to flow. There should be no smoking or
open flame near the faucet at the time it is open.
Hot water produced by this appliance can cause severe
burns due to scalding. The hazard is increased for young
children, the aged or the disabled when water temperatures
exceed 52°C (125°F). Use mixing valvess, also known as
mixing valves, in the hot water system to reduce the risk
of scalding at point-of-use such as lavatories, sinks and
bathing facilities. Such precautions must be followed when
this heater is operated in combination with dishwashing or
space heating applications.

III) INSTALLATION
Unpacking the Water Heater
WARNING
Excessive Weight Hazard
Use two or more people to move and install
water heater. Failure to do so can result in
back or other injury.
Important: Do not remove any permanent instructions,
labels, or the data label from outside of the water heater or
on the inside of panels.
• Remove exterior packaging and place installation com-
ponents aside.
• Inspect all parts for damage prior to installation and start-
up.
• Completely read all instructions before attempting to
assemble and install this product.
If you observe damage to the water heater or any of its components, DO NOT ASSEMBLE OR INSTALL IT OR MAKE
ANY ATTEMPT TO FIX THE DAMAGED PART(S). Contact
the place of purchase for further instructions.
• After installation, dispose of packaging material in the
proper manner.
IMPORTANT:
This water heater must be installed strictly in accordance
with the instructions enclosed, and local electrical, fuel
and building codes. It is possible that connections to the
water heater, or the water heater itself, may develop leaks.
IT IS THEREFORE IMPERATIVE that the water heater be
installed so that any leakage of the tank or related water
piping is directed to an adequate drain in such a manner
that it cannot damage the building, furniture, floor covering, adjacent areas, lower floors of the structure or other
property subject to water damage. This is particularly
important if the water heater is installed in a multi-story
building, on finished flooring or carpeted surfaces. THE
MANUFACTURER WILL NOT ASSUME ANY LIABILITY
for damage caused by water leaking from the water
heater, pressure relief valve, or related fittings. Select a
location as centralized within the piping system as possible. In any location selected, it is recommended that
a suitable metal drain pan be installed under the water
heater. This pan must limit the water level to a MAXIMUM
depth of 45mm (1 3/4 in.) and have a diameter that is a
minimum of 50mm (2 in.) greater than the diameter of the
water heater. Suitable piping shall connect the metal drain
pan to a properly operating floor drain.
Location
Generally, the location selected should be as close to the
wall as practical and as centralized with the piping system
as possible. Heater should be located in an area not subject
to freezing temperatures.
The water heater should be located so that the controls and
drain are easily accessible.

CAUTION: When this water heater is installed directly on
carpeting, carpeting must be protected by a metal or wood
panel beneath the appliance extending beyond the full
width and depth of the appliance by at least 76mm (3 in.)
in any direction, or if the appliance is installed in an alcove
or closet, the entire floor must be covered by the panel.
The panel must be strong enough to carry the weight of the
heater when full of water. Failure to heed this warning may
result in a fire hazard.
Minimum clearances between the heater and combustible/
non combustible materials are 0mm (0 in.) at the sides and
rear; 508mm (20 in.) from the top of water heater and 25mm
(1 in.) around the vent pipe. A minimum of 915mm (3 ft.) of
clearance is required at the front (control) side of the heater
for service.
For a closet installation, the door at burner side should be
openable and a minimum of 102mm (4 in.) clearance is
needed. Water heater is certified for installation on a combustible floor (see Figure 1).
