DO NOT connect this water heater to an existing vent
or chimney; it must be vented separately from all other
appliances, using only approved venting materials.
!
WARNING:
Failure to properly vent the water heater to the outdoors as
outlined above and in the following section can result in
unsafe operation of the water heater causing bodily injury,
explosion, fire or death.

DANGER:
To avoid the risk of fire, explosion, or asphyxiation from
carbon monoxide, NEVER operate the water heater unless
it is properly vented and the vent and combustion air inlet
systems are properly installed as detailed in the "Vent and
Combustion Air-Inlet" section of this manual.
The vent and combustion air inlet pipes must overlap a
minimum of 1/2 in. (1.3 cm) at each joint. It is important that
the vent and combustion air inlet pipes engage fully into any
pipe fitting and be kept in that position until the adhesive has
fully cured. DO NOT drill or punch holes in the plastic pipe or
fittings.

This unit can be vented using only the below
recommended pipe material. Use only 2, 3, or 4 inch
diameter pipe.
Refer to local codes for restrictions on the use of PVC,
