Termination of Multiple Direct Vent Furnaces
Figure 18
If more than one direct vent furnace is to be installed horizontally 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 (non-direct vent) installations.
Refer to the directions furnished with the Side Wall Vent Kit
(p/n 0170K00000S or 0170K000001S) for installation speci-
fications.
C ONDENSATE D RAIN L INES & D RAIN T RAP
A condensing gas furnace achieves its high level of efficiency by extracting heat from the products of combustion to the point where
condensation takes place. The condensate must be collected in the furnace drain trap and routed to an appropriate drain
location in compliance with local and national codes.
Follow the bullets listed below when installing the drain system. Refer to the following sections for specific details concerning furnace
drain trap installation and drain hose hook ups.
• The drain trap supplied with the furnace must be used.
• The drain trap must be primed at time of installation.
• The drain line between furnace and drain location must meet local and nation codes.
