DANGER
WARNING
You can be killed or seriously injured if you don’t immediately follow
instructions.
You can be killed or seriously injured if you don’t follow instructions.
Safety Warning (Flammable Vapours)
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)
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 tempering valves, 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.
Safety Warning (Carbon Monoxide)
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 coverage.
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.
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 sp
ark 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.

or other flammable vapours or liquids in the vicinity of this or any other
appliance can result in serious injury or death.
III) INSTALLATION
Unpacking the Water Heater
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 components 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.
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).

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. GSW
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 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 drain pan to a properly operating floor drain.
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.
