FIGURE 6. UNSTABLE FLAME
CLEARANCES
Minimum clearances between the water heater and
combustible construction are 0 inch at the sides and
rear, 4” (102 mm) at the front, and 6” (153 mm) from the
vent pipe. Clearance from the top of the jacket is 12”
(305 mm).
FIGURE 7. CLEARANCES
A gas water heater cannot operate properly without the
correct amount of air for combustion. Do not install in a
conned area such as a closet, unless you provide air
as described in Air Requirements (page 16). Never
obstruct the ow 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 re or explosion and cause death, serious bodily
injury, or property damage.
FIGURE 8. VENTILATION CLEARANCES
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 ammable 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
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.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
Breathing Hazard - Carbon Monoxide Gas
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. The water
heaters covered by this manual meet or exceed the
Energy Policy Act standards with respect to insulation
and standby heat loss requirements, making an
insulation blanket unnecessary.
Should you choose to apply an insulation blanket to
this heater, you should follow these instructions. See
Leakage Test Points (page 33) for identication of
components mentioned below. Failure to follow these
instructions can restrict the air ow required for proper
combustion, potentially resulting in re, asphyxiation,
serious personal injury or death.
