IImmppoorrttaanntt:: To determine if your application requires 3”
venting, see the Maximum Vent Length
Table.
IImmppoorrttaanntt:: Horizontal venting application must use the
2” x 3” offset reducing coupling. Vertical
venting applications do not require the
reducing coupling to be offset.
NNoottee:: If your furnace comes with a factory supplied 2"
X 3" offset reducing coupling it is used for 3"
vent pipe installation. Make sure the marking
"TOP" is located on the top side of the pipe in
horizontal venting applications. The straight side
of the coupling must be on bottom for proper
drainage of condensate.

Typical Venting
This combustion air intake has a built-in condensate
collection system. Condensate that may collect is
drained by field supplied 1/2" ID tubing. The tubing
must be routed to form a trap and water seal ( see
Figure 1, p. 39, Figure 2, p. 39, and Figure 3, p. 40).
A field supplied hose clamp is recommended but not
be required. The tubing is not under pressure.
Combustion air piping must be square cut and de-
burred for proper drainage. For side entry combustion
inlet applications, ensure the drain is pointed
downwards.
