Installation instructions
3.5Proper 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.
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.
3.6Heater 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
Clearances from any exhaust vent pipe are dependent upon the clearance requirements of the stainless steel vent pipe manufacturer. Single wall stainless steel
3.7Mounting installation
Warning: before starting installation
B Check that there are no loose or
damaged parts inside the appliance
BConfirm the gas type of the heater matches the gas supply you will be connecting the heater, see Fig. 2, page 6.
Front cover should be removed (see i 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.
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.
BSecure 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).
