Side Wall Vent Kit
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
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 (non-direct vent)
installations.
NOTE: Refer to the directions furnished with
the Side Wall Vent Kit (p/n 0170K00000S or
0170K00001S) for installation specifications.
CONDENSATE DRAIN LINES & DRAIN
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" 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.

TRAP
• 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.

NOTE: Drain components shown for information
purposes only. For horizontal installations, a
Horizontal Drain Kit may be needed. Refer to the
Specifications Sheet for kit part number.
General Drain Information
All furnace models come with a factory installed drain trap.
For vertical installations, the trap will remain in the factory
position. 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.
