Installing the 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 Water Heater 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. When such areas cannot be avoided, it is recommended that a suitable catch pan, adequately drained to a safe location be installed under the 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. Minimum Clearance from Combustible and Non-­Combustible Construction. 0" (Zero) (0 cm) 0" (Zero) (0 cm) 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, freezing, etc. If the water heater is installed in a garage, it should be installed so that the direct ignition system and main burner are no less than 18 inches (45 cm) above the garage floor. 1/2" (min) (1.3 cm) Top = 12" (30 cm) 1/2" (min) Raising the gas fired water heater will reduce 12" (min) (1.3 cm) BUT NOT eliminate the possibility of lighting (30 cm) (24" (61cm) minimum is the vapor of any flammable liquids which may recommended for service) be improperly stored or accidentally spilled. Bottom = 12" (30 cm) Front = 12" (30 cm) Back = 0"* G T he water heater should be installed as close as practical to the vent termination Side = 1/2" (1.3 cm) Concentric Vent = 0" to minimize vent length and the number of * (with support bracket) elbows required for venting. G T he water heater should be installed with the proper venting materials and termination suitable for Category III venting or Rheem approved venting. G A fire stop plate should be installed at every penetration of a floor or ceiling if the vent is not running in a fire rated shaft. G F ailure to install and properly vent the water heater to the outdoors as outlined in the Venting Section of this manual can result in unsafe operation. G L ong hot water lines should be insulated to conserve water and energy. G T he water heater and water lines should be protected from exposure to freezing temperatures. G D o not install the water heater in bathrooms, bedrooms, any occupied rooms normally kept closed, or in outdoor areas. G D o not install water heater where subject to vibrations. G D o not install the water heater in Recreational Vehicles, Mobile Homes, Boats and other Watercrafts. G D o not install the water heater near vents for heating or cooling. A minimum of 4 feet (1.2 m) should be maintained. G M inimum water heater clearance from combustible and non-­combustible 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;; and 12" (30 cm) from the top (24" [61 cm] from front and top is recommended for servicing purposes). G M aintain a minimum clearance of 0" (0 cm) around the concentric vent pipe to combustible or non-­combustible construction, unless otherwise specified by vent manufacturer or installed in an enclosed space. 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.
