The inlet air screens provided in the installation instruction packet
are available for the installer to use in the inlet of the combus-
tion air pipe to prevent animals from building nests in the com-
bustion air pipe. Installation of screens, while strongly recom-
mended, is not required and will not affect performance of the
unit.
Direct vent installations require both a combustion air intake
and a vent/flue pipe. The pipes may be run horizontally and exit
through the side of the building or run vertically and exit through
the roof of the building. The pipes may be run through an exist-
ing unused chimney; however, they must extend a minimum of
12 inches above the top of the chimney. The space between the
pipes and the chimney must be closed with a weather tight,
corrosion resistant flashing. Both the combustion air intake and
a vent/flue pipe terminations must be in the same atmospheric
pressure zone. Refer to Vent/Flue and Combustion Air Pipe -
Termination Locations or Concentric Vent Termination for spe-
cific details on termination construction. For details concerning
connection of pipes to the furnace, refer to the Vent/Flue Pipe
and Combustion Pipe - Standard Furnace Connections or Alter-
nate Furnace Connections.

Refer to the following table for applicable length, elbows, and
pipe diameter for construction of the vent/flue and combustion
air intake pipe systems of a direct vent (dual pipe) installation.
The number of elbows tabulated represents the number of el-
bows and/or tees in each (Vent/Flue & Combustion Air Intake)
pipe. Elbows and/or tees used in the terminations must be in-
cluded when determining the number of elbows in the piping
systems.
If the combustion air intake pipe is to be installed above a fin-
ished ceiling or other area where dripping of condensate will be
objectionable, insulation of the combustion air pipe may be re-
quired. Use 1/2" thick closed cell foam insulation such as
Armaflex™ or Insultube™ where required.

The vent/flue and combustion air pipes may terminate verti-
cally, as through a roof, or horizontally, as through an outside
wall.
Vertical pipe terminations should be as shown in the following
figure. Refer to Vent/Flue Pipe and Combustion Pipe - Termina-
tion Locations for details concerning location restrictions. The
penetrations through the roof must be sealed tight with proper
flashing such as is used with a plastic plumbing vent.
