Minimum clearances between the water heater and combustible construction are 0 inch at the sides and rear, 4 inches (102 mm) at the front, and 6 inches (153 mm) from the vent pipe. Clearance from the top of the jacket is 12 inches (305 mm) on most models. Note that a lesser dimension may be allowed on some models, refer to the label attached adjacent to the gas control valve on the water heater, see Figure 9.
FIGURE9.
•Install water heater in accordance with the instruction manual and NFPA 54.
•To avoid injury, combustion and ventilation air must be taken from outdoors.
•Do not place chemical vapor emitting products near water heater.
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 Locating The New Water Heater section. 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.
FIGURE10.
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 available to the general public for external use on gas water heaters are not necessary with Maytag products. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. Your Maytag 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.
•Do not obstruct water heater air intake with insulating blanket.
•Gas and carbon monoxide detectors are available.
•Install water heater in accordance with the instruction manual.
WARNING
Should you choose to apply an insulation blanket to this heater, you should follow these instructions (See Figure 7 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 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 Maytag 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.
