3.5 Proper location for installing your
heater
Carefully select the location of the water heater. For
your safety and for proper heater operation, you must
provide combustion air to the heater and a proper
exhaust vent system.
Follow the guidelines below:
B
1. Locate the heater where venting, gas and
plumbing connections are feasible and convenient.
B
2. The hot water lines should be kept short and
insulated to save energy. Centrally locating the water
heater is recommended to keep hot water
distribution times even throughout the structure.
3.6 Heater placement and clearances
The water heater is approved for installation on a
combustible wall (see
chapter 3.7 Mounting
installation) provided the floor covering below
the heater is noncombustible
. For installations in an
alcove or closet, maintain the minimum clearances to
combustible and non-combustible materials. See Fig. 7
and Table 1 on page 8.
Clearances from any exhaust vent pipe are dependent
upon the clearance requirements of the stainless steel
vent pipe manufacturer. Single wall stainless steel
(AL29-4C) vent pipe (vent type rated for Category III
appliances) must be used when exhaust venting this
appliance. See chapter 3.3 (page 9) Venting.
3.7 Mounting installation
If wall is sheathed with plaster or drywall, it is recom-
mended that two support boards, either 1”x4” or 1/2"
(minimum) plywood first be attached across a pair of
studs, see Fig. 24.
B
Secure the wall mounting bracket provided with the
heater to the wall surface. The heater must be kept
level on the wall surface (see Fig. 25).
B
Hang the appliance on the bracket, see Fig. 26.

Warning: The water in this water
heater is cold and always remains cold
except for the times the burner is on. In
the event of power outage in
conjunction with freezing temperatures,
it is recommended that the heater be
drained.
See chapter 6.2, page 32 “Winterizing”
for draining instructions.
Warning: Flammable materials,
gasoline, pressurized containers, or any
other items or articles that are potential
fire hazards must NOT be placed on or
adjacent to the heater. The appliance
area must be kept free of all
combustible materials, gasoline and
other flammable vapors and liquids.
Warning: before starting
installation
B
Check that there are no loose or
damaged
parts inside the
appliance
B
Confirm the gas type of the heater
matches the gas supply you will be
connecting the heater, see Fig.
2,
page 6.
i
Front cover should be removed (see
instructions on page 6) in order to inspect
components visually.
Warning: Do not install this appliance
on a carpeted wall. The heater must be
mounted on a wall using appropriate
anchoring materials.
Warning: In areas where outside
temperature is routinely below 32°F and
the heater is to be installed on the inside
of an exterior wall, a minimum 2" air gap
or rigid insulation between the heater
back and the wall is recommended.
