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.
FIGURE 9.
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.
FIGURE 10.
If this water heater will be used in beauty shops, barber shops,
cleaning establishments, or self-service laundries with dry
cleaning equipment, it is imperative that the water heater or
water heaters be installed so that combustion and ventilation
air be taken from outside these areas.
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.
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.
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.
Do not obstruct water heater air
intake with insulating blanket.
Install water heater in accordance
with the instruction manual.
Gas and carbon monoxide
detectors are available.
