PRODUCT DESIGN
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 appropri-
ate 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 in-
stalled in the drain line, near the cooling coil, to relieve
positive air pressure from the coil's plenum. This is nec-
essary to prohibit any interference with the function of
the furnace's drain trap.
• If a cooling coil is installed on top of an upflow fur-
nace, and a common drain line is used for the cooling
coil and the furnace, the cooling coil drain must be
vented to avaoid inference with furnace draining.

The wiring harness is an integral part of this furnace. Field
alteration to comply with electrical codes should not be re-
quired. Wires are color coded for identification purposes.
Refer to the wiring diagram for wire routings. If any of the
original wire as supplied with the furnace must be replaced, it
must be replaced with wiring material having a temperature
rating of at least 105° C. Any replacement wiring must be a
copper conductor.
