Vent Pipe Installation
Horizontal Vent Termination- PVC/CPVC Materials Only
Do Not Use TWHHORHOOD as a vent termination unless there is at least 3ft. (0.9m) or more distance between the intake pipe and exhaust pipe.
Installations where 3ft (0.9m) distance cannot be met, use 90° elbows as the vent terminations as shown in the illustrations below.

WARNING
If the distance between the air inlet and exhaust vent terminations is too short, the water heater
will draw in the exhaust gases through the intake. There is a risk of inadequate combustion air
for the water heater, increasing Carbon Monoxide (CO) emissions and noise due to vibration.
Termination elbows must be oriented vertically, pointing directly downward. Attempts 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.

Ensure at least 3ft (0.9m) or more distance between
the near edge of the air intake pipe or exhaust pipe
to the inside corner of a wall.

Ensure at least 3ft (0.9m) or more distance between
edge of air intake pipe or exhaust pipe and corner wall.
Intake
Upper side is exhaust, lower side is intake.
The reverse connection is not allowed.
Ensure at least 1ft (0.3m) or more distance between
intake pipe and exhaust pipe.
The distance is measured at the outlets of
intake port (terminal) and exhaust port (terminal).
Intake and exhaust should face the same direction.

The side distant from wall is intake, the side near the
wall is exhaust.
The reverse connection is not allowed.
Ensure at least 1ft (0.3m) or more distance between
intake pipe and exhaust pipe.
