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.
VENT/INTAKE TERMINATIONS FOR INSTALLATION OF MULTIPLE
DIRECT VENT FURNACES
If more than one direct vent furnace is to be installed vertically
through a common roof top, maintain the same minimum clear-
ances between the exhaust vent and air intake terminations of
adjacent units as with the exhaust vent and air intake termina-
tions of a single unit.
If more than one direct vent furnace is to be installed horizon-
tally through a common side wall, maintain the clearances as in
the following figure. Always terminate all exhaust vent outlets
at the same elevation and always terminate all air intakes at the
same elevation.
CONCENTRIC VENT TERMINATION
Refer to the directions provided with the Concentric Vent Kit
(DCVK) for installation specifications.
SIDE WALL VENT KIT
This kit is to be used with 2” or 3” direct vent systems. The
vent kit must terminate outside the structure and may be in-
stalled with the intake and exhaust pipes located side-by-side or
with one pipe above the other. These kits are NOT intended for
use with single pipe (indirect vent) installations.
Refer to the directions furnished with the Side Wall Vent Kit
(p/n 0170K00000S or 0170K00001S) for installation speci-
fications.
