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. 

A condensing gas furnace achieves its high level
of e󰀩ciency 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 specic 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.

All furnace models come with a factory installed drain trap.
For vertical installations, the trap will remain in the factory
position except for a counterow 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
