  • Page 4: Location Requirements

    WARNING FLAMMABLES Flammable Vapors FIRE AND EXPLOSION HAZARD Can result in serious injury or death Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance. Storage of or use of gasoline or other flammable vapors or liquids in the vicinity of this or any other appliance can result in serious injury or death.
  • Page 5: Clearances And Accessibility

    IMPORTANT: The water heater should be located in an area where leakage of the tank or connections will not result in damage to the area adjacent to the water heater or to lower floors of the structure. Due to the normal corrosive action of the water, the tank will eventually leak after an extended period of time.
  • Page 6: Gas Supply

    Gas Supply WARNING Explosion Hazard Use a new CSA approved gas supply line. Install a shut-off valve. Do not connect a natural gas water heater to an L.P. gas supply. Do not connect an L.P. gas water heater to a natural gas supply.

  • Page 8: Unconfined Space

    Unconfined Space A water heater in an unconfined space uses indoor air for combustion and requires at least 50 cubic feet for each 1,000 BTUH of the total input for all gas appliances. The table below shows a few examples of the minimum square footage (area) required for various BTUH inputs.
  • Page 9: All Air From Outdoors

    All Air from Outdoors Outdoor fresh air can be provided to a confined area either directly or by the use of vertical and horizontal ducts. The fresh air can be taken from the outdoors or from crawl or attic spaces that freely communicate with the outdoors. Attic or crawl spaces cannot be closed and must be properly ventilated to the outside.
  • Page 10: Vent Pipe System

    Vent Pipe System This water heater uses a non-direct, single-pipe vent system to remove exhaust gases created by the burning of fossil fuels. Air for combustion is taken from the immediate water heater location or is ducted in from the outside (see “Combustion Air Supply and Ventilation”).
  • Page 11: Chimney Connection

    Chimney Connection IMPORTANT: Before connecting a vent to a chimney, make sure the chimney passageway is clear and free of obstructions. The chimney must be cleaned if previously used for venting solid fuel appliances or fireplaces. Also consult local and state codes for proper chimney sizing and application or, in the absence of local and state codes, the “National Fuel Gas Code”, ANSI Z223.1(NFPA 54)-latest edition.
  • Page 12: Water System Piping

    Water System Piping Piping Installation Piping, fittings, and valves should be installed according to the installation drawing (Figure 13). If the indoor installation area is subject to freezing temperatures, the water piping must be protected by insulation. Water supply pressure should not exceed 80% of the working pressure of the water heater.
  • Page 13: Temperature And Pressure Relief Valve

    Closed System/Thermal Expansion Periodic discharge of the temperature and pressure relief valve may be due to thermal expansion in a closed water supply system. The water utility supply meter may contain a check valve, backflow preventer or water pressure reducing valve.
