Venting
_WARNING
To insure proper venting of this gas-fired water
heater, the correct vent pipe diameter must be uti-
lized. Any additions of other gas appliances on vent
with this water heater will adversely affect the oper-
ation of the water heater.
The combustion alld ventilation air flow must not be obstructed.
AWARNING
The power vent water heater requires its own (sepa-
rate) venting system. It cannot be connected to an ex-
isting vent pipe or chimney. It must be terminated to
the outdoors. Failure to properly install the venting sys-
tem can result in asphyxiation, a fire or explosion and
can cause DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE.
&WARNING
Chemical vapor corrosion of the flue and vent sys-
tem may occur if air for combustion contains certain
chemical vapors. Spray can propellants, cleaning sol-
vents, refrigerator and air conditioner refrigerants,
swimming pool chemicals, calcium and sodium chlo-
ride, waxes, bleach, and process chemicals are typi-
cal compounds which are potentially corrosive.
