Condensate Piping
This unit is designed for either right- or left-side exit of
condensate piping. Route the condensate drainiine only
within the conditioned space: this prevents possible
freezing of the condensate, which would block the drain-
line. Use an electric heat cable if you route the conden-
sate line through unconditioned areas.
A CAUTION
1 - Determine which side condensate will exit the unit.
2- Connect 1/2 inch (13 mm) plastic pipe plug (pro-
vided) in the unused end of the condensate trap.
Install plug so that it is sealed water tight yet able to
be removed. Do not permanently seal the connec-
tion. Teflon tape is recommended to seal joint. See
figure 21.

3 - Use the providedcondensate drain adapter (3/4" x
1/2") and a field-providednipple to carry drainage
outside the cabinet. If a fieldsubstitute is needed, 1/2
inch CPVC x 1/2 inch MPT adapter and 1/2 inch
CPVC is acceptable for use.
4 - Glue nipple to the adapter using the procedures out-
lined in the "Joint Cementing Procedures" section.
The nipple/adapter assembly should be connected
in a non-permanentmanner and must be water tight.
Teflon tape is recommended to seal the joint.
For Right-Hand Side Condensate Exit:
Install the nipple/adapter assembly from the out-
side of the cabinet and insert the adapter intothe
threaded opening in the condensate trap.
For Left-Hand Side Condensate Exit:
Insert nipple/adapterassemblyfrom the left hand
side of the cabinet and through the combustion air
inducer mounting structure into the threaded
opening in the condensate trap.
5 - Connect field-supplied plumbing to nipple and route
to open drain. Plumbing should be vented to a point
higher than the condensing coil. See figure 22.
