Venting
A 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 and ventilation air flow must not be obstructed.
A WARNING
Chemical vapor corrosion of the flue and vent sys­
tem may occur if air for combustion contains certain
chemical v^ors. 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.
AWARNING
The power vent water heater requires its own (sepa­
rate) venting system. It cannot be connected to iui 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.

sent a serious health risk or asphyxiation.
