CAUTION
FROZEN AND BURST WATER PIPE HAZARD
Failure to protect against the risk of freezing may result in
property damage.
Special precautions MUST be made if installing furnace in an
area which may drop below freezing. This can cause improper
operation or damage to equipment. If furnace environment has
the potential of freezing, the drain trap and drain line must be
protected. The use of accessory drain trap heaters, electric
heat tape and/or RV antifreeze is recommended for these
installations.

CAUTION
PROPERY DAMAGE HAZARD
Failure to follow this caution may result in burst water pipes
and/or property damage.
If a condensate pump is installed, a plugged condensate drain
or a failed pump may cause the furnace to shut down. Do not
leave the home unattended during freezing weather without
turning off water supply and draining water pipes or otherwise
protecting against the risk of frozen pipes.
DO NOT trap the drain line in any other location than at the
condensate drain trap supplied with the furnace. If possible, DO
NOT route the drain line where it may freeze. The drain line
must terminate at an inside drain to prevent freezing of the
condensate and possible property damage.
Special precautions MUST be made if installing furnace in an
area which may drop below freezing. This can cause improper
operation or damage to the equipment. If the furnace
environment has the potential of freezing, the drain trap and
drain line must be protected. A self
−
regulating, shielded and
waterproof heat tape rated at 3 to 6 watt per foot (10 to 20 watt
per meter) at 115 volt, 40
°
F (4
°
C) may be used to help provide
freeze protection. Wrap the drain trap and drain line with the
heat tape and secure with appropriate plastic ties. Follow the
heat tape manufacturer’s recommendations. Prime the trap
before furnace operation.
Upflow/Downflow Orientation
In the Upflow or Downflow orientation, the condensate trap is
inside the furnace casing. The condensate drain must be
routed from the trap through the furnace casing. The
condensate drain can be routed through the left or right side of
the casing. (The left or right side is as you are viewing/facing
the furnace from the front.) The furnace condensate drain can
be connected to the indoor coil condensate drain, humidifier or
auxiliary drain traps as shown in
NOTE
: On narrower casings, it may be easier to remove the
condensate trap, connect the drain line components and
re-install the condensate trap. Read the steps thoroughly to
familiarize yourself with the required steps.
For Right Side Condensate Drain:
1. Remove the 7/8

2. Remove the pre

formed rubber drain tube and two
spring clamps from the loose parts bag.
3. Slide a spring clamp 1 in. (25 mm) down the plain end
(the end without the formed grommet) of the drain tube.
4. From inside the casing, insert the formed grommet end
of the elbow through the 7/8
−
in. knockout in the casing.
5. Pull the grommet through the casing from the outside
until it is seated in the knockout
6. Attach the plain end of the drain elbow to the outlet stub
on the drain trap. Secure the drain elbow to the trap with
the spring clamp.
The remaining drain line can be constructed from field supplied

sliding a spring clamp over the open end of the grommet
on the outside of the furnace casing.
