Concentric Vent Termination

Refer to the directions provided with the Concentric Vent Kit
(CVENT) 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
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.
Refer to the directions furnished with the Side Wall Vent
Kit (p/n 0170K00000S or 0170K00001S) for installation
specifications.

Condensate Drain Lines & Drain Trap
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 col-
lected 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 national 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, 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.

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 posi-
tion. NOTE: Both sides of the drain trap must be primed
prior to initial furnace start up

Field Supplied Drain

Drain the furnace and air conditioning coil if applicable, in
compliance with code requirements. In horizontal installa-
tions, a field installed rubber coupling will allow the drain
trap to be removed for cleaning. The drain trap must be
primed before initial furnace start up. When an air condi-
tioning coil drain is connected to the field supplied furnace
drain, it must be vented with an open tee installed at a
height no higher than the bottom of the furnace collector
box to prevent air conditioning condensate from backing
up into the furnace if the common drain became blocked.
