4.6 Heater placement and clearances
The water heater design is approved for installation on a combustible
wall (see chapter 4.7 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. 6, page 10.
4.7 Hanging appliance on the wall
If wall is sheathed with plaster or drywall, it is recommended that two
support boards, either 1"x 4" or 1/2" (minimum) plywood first be
attached across a pair of studs, see fig. 29, page 25.
▶ Secure the wall mounting bracket provided with the heater to a wall
surface. The heater must be kept level on the wall surface, see fig.
30, page 26.
▶ Hang the appliance on the bracket, see fig. 31, page 27.

NOTICE: Risk of appliance freezing!
▶ 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 7.2, page 37 “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: Severe personal injury and property
damage!
Before mounting appliance:
▶ Check that there are no loose or damaged parts
inside the appliance.
▶ Confirm that the gas type of the heater matches the
gas supply you will be connecting the heater, see
Fig.2, page 8.
Front cover should be removed (see instructions on page
8) 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.
NOTICE: Risk of appliance freezing!
▶ In areas where outside temperature is routinely
below 32°F (0 °C) 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.
