HYDROGEN GAS IS EXTREMELY FLAMMABLE. To reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system. If hydrogen is present, there will probably be an unusual sound such as air escaping through the pipe as the water begins to flow. THERE SHOULD BE NO SMOKING OR OPEN FLAME NEAR THE FAUCETATTHE TIME IT IS OPEN. INSULATION BLANKETS Insulation blankets available to the general public for external use on gas water heaters are not approved for use on your water heater. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. Your water heater meets and exceeds the National Appliance Energy Conservation Act standards with respect to insulation and standby loss requirements, making an insulation blanket unnecessary. WARNING Should you choose to apply an insulation blanket to this heater, you should follow these instructions (See Figure 1 for identification of components mentioned below). Failure to follow these instructions can restrict the air flow required for proper combustion, potentially resulting in fire, asphyxiation, serious personal injury or death. • Do not cover the outer door, thermostat or temperature & pressure relief valve. • Do not allow insulation to come within 2 inches of dilution air inlet on the blower to prevent blockage of the dilution air. • Do not allow insulation to come within 2" of the floor to prevent blockage of combustion air flow to the burner. • Do not cover the instruction manual. Keep it on the side of the water heater or nearby for future reference. • Do obtain new warning and instruction labels for placement on the blanket directly over the existing labels. • Do inspect the insulation blanket frequently to make certain it does not sag, thereby obstructing combustion air flow. 3 INSTALLATION REQUIRED ABILITY INSTALLATION OR SERVICE OF THIS WATER HEATER REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR SUPPLY, VENTING AND GAS SUPPLYARE REQUIRED. GENERAL The installation must conform to these instructions and the local code authority having jurisdiction. In the absence of local codes, the installation must comply with the current editions of the National Fuel Gas Code ANSI Z223.1/NFPA 54 and the National Electrical Code, NFPA 70. The former is available from the Canadian Standards Association, 8501 East Pleasant Valley Road, Cleveland, OH 44131, and both documents are available from the National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02269. GROUNDING The water heater when installed must be grounded in accordance with local codes, or in the absence of local codes: In the United States The National Electric Code, ANSI/NFPA 70. HIGH ALTITUDE INSTALLATION WARNING STANDARD MODELS ARE FOR INSTALLATION UP TO 2,000 FEET (610m) ABOVE SEA LEVEL. IF A STANDARD MODEL IS INSTALLED ABOVE 2,000 FEET (610m), INPUT RATING SHOULD BE REDUCED AT A RATE 4 PERCENT FOR EACH 1,000 FEET (305m) ABOVE SEA LEVEL WHICH REQUIRES REPLACEMENT OF THE BURNER ORIFICE IN ACCORDANCE WITH THE NATIONAL FUEL GAS CODE (ANSI Z223.1/NFPA 54). FAILURE TO REPLACE THE STANDARD ORIFICE WITH A HIGH ALTITUDE ORIFICE WHEN INSTALLED ABOVE 2,000 FEET (610m) COULD RESULT IN IMPROPER AND INEFFICIENT OPERATION OF THE WATER HEATER, PRODUCING CARBON MONOXIDE GAS IN EXCESS OF SAFE LIMITS, WHICH COULD RESULT IN SERIOUS INJURY OR DEATH. CONTACT YOUR LOCAL GAS SUPPLIER FOR ANY SPECIFIC CHANGES WHICH MAY BE REQUIRED IN YOUR AREA. LOCATION OF HEATER The heater is design certified by the Canadian StandardsAssociation for installation on combustible flooring in a closethaving minimum clearances from combustible material of: 0" clearance from sides and rear, 5" from the front and 12" from the top. (Standard clearance.) If clearances stated on the heater differ from standard clearances, install water heater accordingto clearances stated on heater. Adequate clearance for servicing this appliance should beconsidered before installation, such as changing the anodes, etc. A minimum clearance of 5" must be allowed for access to replaceable parts such as the thermostats, drain valve and reliefvalve. When installing the heater, consideration must be given to properlocation. Location selected should be as close to the wall as practicable and as centralized with the water piping system aspossible. AIR REQUIREMENTS Dilution air temperature must be 100°F or less. In calculating the free area of a vent opening, the blocking effect of screens, louvers and grills should be considered. Screens shall not be of a mesh smaller than 1/4 inch square. If the free area is not known, the current edition of National Fuel Gas Code ANSI Z223.1/NFPA 54 recommends using figures of 20-25 percent free area for wood louvers or 60-75 percent for metal grills or louvers.
