Condensate Disposal Installation
The condensate drain should be routed directly to a locally
acceptable disposal area. The condensate drain line
should not be run directly to the outdoors especially in
colder climates where temperatures may cause the
condensate to freeze in the drain line.
In horizontal installations where clearance beneath the
unit is limited, an alternate method for condensate dis-
posal trap installation may be used (see
Horizontal
Installation – Tight Clearance Below Unit
on page 17).
Upflow Installation
Install the condensate drain line to the unit as follows. The
condensate can be drained from either the right or left
side of the furnace. Install the 1/2" NPT x 3/4" PVC
adapter (supplied) in the drain on the side that the draining
will occur. Install the plastic pipe plug opposite of the
drain. Using 3/4" PVC pipe, make a connection from the
adapter just installed to extend just outside the unit. Install
a 3/4" PVC tee as shown in Figure 17. From the tee,
install the drain to the disposal area. The top of the tee
must be left open for proper condensate drainage.
Horizontal Installation – Right to Left Airflow
Furnace must be mounted such that the side through
which the condensate will drain is elevated a minimum of
9" above a surface such as a floor.
Install unit at a slight pitch forward (see Figure 18).
1. Relocate the 1/2" NPT plug installed on the flue pan to
one side of the internal trap assembly (as shown in
Figure 19).
2. Connect the 1/2" NPT plug (supplied) to the opposite
side of the internal trap assembly from the plug
installed in Step 1.
3. Insert trap assembly (supplied) into flue pan (see
Figure 20).
