If more than one direct vent furnace is to be installed vertically through
a common roof top, maintain the same minimum clearances be-
tween the exhaust vent and air intake terminations of adjacent units
as with the exhaust vent and air intake terminations of a single unit.
If more than one direct vent furnace is to be installed horizontally
through a common side wall, maintain the clearances as in the fol-
lowing figure. Always terminate all exhaust vent outlets at the same
elevation and always terminate all air intakes at the same elevation.

IDE ALL ENT IT
This kit is to be used with 2" or 3" direct vent systems. The vent kit
must terminate outside the structure and may be installed 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 (indi-
rect vent) installations.
Refer to the directions furnished with the Side Wall Vent Kit (p/n
0170K00000S or 0170K000001S) for installation specifications.

ONDENSATE RAIN INES
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.
• The drain line between furnace and drain location must maintain a 1/4 inch per foot downward slope toward the drain.
• Do not trap the drain line in any other location than at the drain trap supplied with the furnace.
• If the drain line is routed through an area which may see temperatures near or below freezing, precautions must be
taken to prevent condensate from freezing within the drain line.
• If an air conditioning coil is installed with the furnace, a common drain may be used. An open tee must be installed in
the drain line, near the cooling coil, to relieve positive air pressure from the coil's plenum. This is necessary to prohibit
any interference with the function of the furnace's drain trap.
NOTE: In vertical installations, air conditioning coil condensate may drain into the furnace trap as long as there is a trap
between the coil and the furnace trap and the drain pipe is not terminating below the water level of the furnace trap.

ENERAL RAIN NFORMATION
All furnace models come with a factory installed drain trap. For vertical installations, the trap will remain in the factory
position except for a counterflow when the installer desires the drain to exit the right side. All furnace models installed
horizontally require the trap to be relocated. Many drain hoses have a built–in grommet which will provide a cabinet seal when
installed. See instructions below for your model and installation position. NOTE: Both sides of the drain trap must be
primed prior to initial furnace start up
