Condensate Piping
This unit is designed for either right- or left-side exit of
condensate piping. Refer to Figure 35 and Figure 36 for
condensate trap locations. Figure 41 and Figure 42 show
trap assembly using 1/2” PVC or 3/4” PVC.
NOTE:
If necessary the condensate trap may be installed
up to 5’ away from the furnace. Use PVC pipe to connect
trap to furnace condensate outlet. Piping from furnace
must slope down a minimum of 1/4” per ft. toward trap.

1.
Determine which side condensate piping will exit the
unit, location of trap, field-provided fittings and length
of PVC pipe required to reach available drain.
1.
Use a large flat head screw driver or a 1/2” drive
socket extension and remove plug (Figure 35) from
the cold end header box at the appropriate location
on the side of the unit. Install provided 3/4 NPT street
elbow fitting into cold end header box. Use Teflon tape
or appropriate pipe dope.
NOTE:
Cold end header box drain plugs are factory
installed. Check the unused plug for tightness to
prevent leakage.
2.
Install the cap over the clean out opening at the base
of the trap. Secure with clamp. See Figure 41 and
Figure 42.
3.
Install drain trap using appropriate PVC fittings, glue
all joints. Glue the provided drain trap as shown in
Figure 41 and Figure 42. Route the condensate line to
an open drain. Condensate line must maintain a 1/4”
downward slope from the furnace to the drain.
When combining the furnace and evaporator coil
drains together, the A/C condensate drain outlet must
be vented to relieve pressure in order for the furnace
pressure switch to operate properly.
IMPORTANT
4.
Figure 38 shows the furnace and evaporator coil
using a separate drain. If necessary, the condensate
line from the furnace and evaporator coil can drain
together. See Figure 39. The field provided vent must
be a minimum 1” to a maximum 2” length above the
condensate drain outlet connection.
NOTE:
If necessary the condensate trap may be
installed up to 5 feet away from the furnace. Piping
from furnace must slope down a minimum of 1/4” per
ft. toward trap.
NOTE:
Appropriately sized tubing and barbed fitting
may be used for condensate drain. Attach to the drain
on the trap using a hose clamp. See Figure 37.
