Condensate Piping
This unit is designed for either right or left side exit of
condensate piping in downflow applications.
Figure 43 for condensate trap locations.
NOTE: If necessary the condensate trap may be installed
up to 5 feet away using PVC pipe from the furnace. 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.
2. Use a large flat head screw driver or a 1/2" drive socket
extension and remove plug (Figure 43) 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.
3. Install the cap over the clean out opening at the base
of the trap. Secure with clamp. See Figure 48.
4. Install drain trap using appropriate PVC fittings, glue
all joints. Glue the provided drain trap as shown in
Figure 48. Route the condensate line to an open drain.
Condensate line must maintain a 1/4" downward slope
from the furnace to the drain.
Do Not use copper tubing or existing copper condensate
lines for drain line.
