(vent pipe, air intake pipe, vent cap, elbows etc.) must be replaced with the vent system supplied with
the new water heater.
Venting
CAUTION: If there are any
damaged parts, DO NOT install the
water heater. Report any damage to
your distributor or to the carrier.
NOTICE: The four fasteners that are
required to secure the vent cap to the
external wall are not provided. These
should be screw type (not nails) chosen
for the type of construction and obtained
locally
DANGER: Failure to
install the venting system
and properly vent the water
heater to the outdoors as
outlined in the Venting
section of this manual will
result in unsafe operation of
the water heater causing
bodily injury, explosion,
fire or death. To avoid the
risk of fire, explosion, or
asphyxiation from carbon
monoxide, NEVER operate
the water heater unless it is
properly vented and has
adequate air supply for
proper operation as
outlined in the Venting
section of this manual.
See the back page of this manual
