Installation Instructions (cont’d)
AWARNING
A gas water heater cannot operate properly without the cor­
rect amount of air for combustion. Do not install in a con­
fined area such 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 company. Failure to provide the
proper amount of combustion air can result in a lire or explo­
sion and can cause DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE.
AWARNING
If this water heater wll 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. Refer to the “Locating
The New Water Heater” section of this manual and also the
latest edition of the National Fuel Gas Code, ANSI Z2Z3.I, also
referred to as NFPA 54 for specifics provided concerning air
required.
Combustion Air and Ventilation
When determining the installation location for a power vent
water heater, snow accumulation and drifting should be consid­
ered in areas where applicable.
