Terminating the Vent
(A) Two-Pipe Sidewall Venting
The following PVC terminals listed in the table below have been approved to be adequate for the units
mentioned in this manual.
Before installing the water heater, determine what type of vent termination is
appropriate for the installation location and materials. The following sections describe
some typical venting configurations, but do not include all possible options. The examples
shown below and the following pages are possible indoor venting options.

• Only the termination models listed in this manual are approved for use with this appliance
• Only terminations produced by the same manufacturer as the vent system must be used.
• Refer to the vent manufacturer’s instructions for detailed installation procedures and guidelines.
The vent system must be installed by an authorized technician or licensed professional. Improper
installation may cause appliance failure, property damage, severe personal injury, or death.
Improper installation will also void the warranty of the water heater.
If the distance between the air inlet and exhaust vent terminations is less than 7 ft. (2.1 m), the
water heater will draw in exhaust gases through the intake. This creates a risk of inadequate
combustion air for the water heater, which can increase the amount of Carbon Monoxide (CO)
emissions and noise due to vibration.
• Termination elbows must be oriented vertically, ensuring they point directly downward.
Attempt to prevent exhaust air from entering the air inlet by angling termination elbows in
directions other than directly downward will increase the risk of freezing.
• Reversing the air intake and exhaust pipes is not allowed. Carbon Monoxide (CO) emissions
and noise due to vibration will increase.
In case of severe weather, such as an earthquake, tornado, or other natural disasters, have a
trained professional check the vent pipe for any damage, that the exhaust flows normally, and
the unit functions properly.
• Install the bird screen at the end of the terminal elbow when a two-pipe sidewall venting
method is applied.
• If glue and other solvent cement are used during the installation, please follow the
manufacturer’s instructions when using.
• Please refer to the illustrations on the following page for the dimension requirements when
using this method of venting.
