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”
.
MAKE SURE THE FLOW OF COMBUSTION AND VENTI-
LATION AIR IS NOT RESTRICTED.
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 INTER-
NAL DAMAGE
and are not subject to warranty coverage.
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 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.
Location Requirements
Do not use or store flammable products such as gasoline,
solvents or adhesives in the same room or area near the
water heater. If such flammables must be used, all gas
burning appliances in the vicinity must be shut off and their
pilot lights extinguished. Open the doors and windows for
ventilation while flammable substances are in use.
Site Location
•
The water heater must be installed indoors and in a ver-
tical position on a level surface.
Note:
The water heater may be installed in a closet with a
door off a bedroom or bathroom providing the units are
installed and vented per the manufacturer’s instructions.
•
Consider the air intake and exhaust vent system piping
when selecting the water heater location. The venting
system must be able to run from the water heater to the
termination with a minimal length and number of
elbows. The venting system must comply with the
requirements set forth in the venting section of this
manual.
•
Locate the water heater near the existing gas piping. If
installing a new gas line, locate the water heater to min-
imize the pipe length and elbows.
Note:
This water heater must be installed in accordance
with all local and provincial or state codes or, in the absence
of such, the latest edition of
“Natural Gas and Propane
Installation Code” CAN/CSA-B149.1
(Canada), or
“National Fuel Gas Code” ANSI Z223.1 (NFPA 54)
(U.S.A.).

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 relat-
ed 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 particular-
ly 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.
When used with a fuel-fired heater, this drain pan must not
restrict combustion air flow.

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.
