Installing the (OUTDOOR) water heater:

This water heater must be installed in accordance with these instructions, local codes, utility company requirements and/or in the absence of local codes, use the latest edition of the American National Standard/National Fuel Gas Code. A copy can be purchased from either the American Gas Association, 400 North Capitol Street Northwest, Washington, DC 20001 as ANSI standard Z223.1 or National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02269 as NFPA 54. In Canada, the latest edition of the CSA B149.1 Natural Gas and Propane Installation, and the Canadian Electrical Code, CSA C22.1 Part 1, in the absence of local codes.

Location of the OUTDOOR water heater

!WARNING: Combustible construction refers to adjacent walls and ceilings and should not be confused with combustible or flammable products and materials. Combustible and/or flammable products and materials should never be stored in the vicinity of this or any gas appliance.

This water heater is for OUTDOOR installation ONLY!

This water heater is an outdoor model and must be mounted vertically. It must not be installed indoors or in a confined space.

The water heater should be installed close to the most frequently used outlet and its position chosen with safety and service in mind.

Make sure people (particular children, disabled, and elderly) will not touch the hot water outlet or the flue terminal. The flue terminal and air inlet must be clear of obstruction and shrubbery.

The water heater should not be located in an area where leakage of the heat exchanger or connections will result in damage to the area adjacent to it or to lower floors of the structure.

A gas fired water heater or any other appliance should not be installed in a space where liquids which give off flammable vapors are to be used or stored. Such liquids include gasoline, LP gas (butane or propane), paint or adhesives and their thinners, solvents or removers.

Because of natural air movement in a room or other enclosed space, flammable vapors can be carried some distance from where their liquids are being used or stored. The open flame of the water heater’s main burner can ignite these vapors, causing an explosion or fire which may result in severe burns, death or property damage.

The water heater must be located so it is not subject to physical damage, for example, by moving vehicles, area flooding, etc.

●The water heater should be installed vertically with the water, gas and power connections on the underside pointing toward the ground.

●Failure to properly install the water heater outdoors as outlined in this manual can result in unsafe operation.

●Hot and cold water lines should be insulated to conserve water and energy.

●The water heater and water lines should be protected from exposure to freezing temperatures.

●Do not install water heater where subject to vibrations.

●Do not install the water heater in Recreational Vehicles, Mobile Homes, Boats and other Watercrafts.

●Do not install the water heater near vents for heating or cooling. A minimum of 4 feet should be maintained.

●Minimum clearance from combustible and noncombustible construction is 1/2” (1.3 cm) sides, 0” rear (with support bracket); 12” (30 cm) from the bottom; 12” (30 cm) from the front of the water heater; (24” [61 cm] from front recommended for servicing purposes).

If the clearances stated on the Instruction/ Warning Label, located on the front panel of the heater differ, install the water heater according to the clearances stated on the label.

!CAUTION:

Protect plastic, paint or other items sensitive to heat using non-combustible insulation if these are exposed to the flue exhaust even though they may be more than 24” (61 cm) away from the water heater.
