Also, the water heater must be located and/or protected so it is not subject to physical damage by a moving vehicle.
This water heater must not be installed directly on carpeting. Carpeting must be protected by metal or wood panel beneath the appliance extending beyond the full width and depth of the appliance by at least 3 inches (76.2 mm) in any direction, or if the appliance is installed in an alcove or closet, the entire floor must be covered by the panel. Failure to heed this warning may result in a fire hazard.
FIGURE 3.
Minimum clearances between the water heater and combustible and noncombustible construction are 0” at the sides and rear, 4” at the front, and 6” from the vent pipe. Clearance from the top of the draft hood is 12”. Refer to the label on the water heater located adjacent to the gas control valve for all clearances.
A gas water heater cannot operate properly without the correct amount of air for combustion. Do not install in a confined area such as a closet, unless you provide air as shown in the Typical Installations, see Figure 2 page 6. Never obstruct the flow of ventilation air. If you have any doubts or questions at all, call your gas supplier. Failure to provide the proper amount of combustion air can result in a fire or explosion and cause death, serious bodily injury, or property damage.
If this water heater will be used in beauty shops, barber shops, cleaning establishments, or
Propellants of aerosol sprays and volatile compounds, (cleaners, chlorine based chemicals, refrigerants, etc.) in addition to being highly flammable in many cases, will also change to corrosive hydrochloric acid when exposed to the combustion products of the water heater. The results can be hazardous, and also cause product failure.
INSULATION BLANKETS
Insulation blankets are available to the general public for external use on gas water heaters but are not necessary with these products. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. Your water heater meets or exceeds the National Appliance Energy Conservation Act standards with respect to insulation and standby loss requirements, making an insulation blanket unnecessary.
Should you choose to apply an insulation blanket to this heater, you should follow these instructions (For identification of components mentioned below, see Figure 1). 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 apply insulation to the top of the water heater, as this will interfere with safe operation of the draft hood.
•Do not cover the outer door, thermostat or temperature & pressure relief valve.
•Do not allow insulation to come within 2” (50.8 mm) 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 from the manufacturer 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.
