NOTE - Do not discharge exhaust gases directly into any chimney or vent stack. If ver

inside chimney until the pipe open end is above top of chimney and terminate as illus
trated. In any exterior portion of chimney, the exhaust vent must be insulated.

Condensate Piping
This unit is designed for either right‐ or left‐side exit of con
densate piping. Refer to figure 42 for condensate trap loca
tions.
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.

1-1/2 in.
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 42) 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 appropri
ate pipe dope.
3 - Install the cap over the clean out opening at the base
of the trap. Secure with clamp. See figure 47.
4 - Install drain trap using appropriate PVC fittings, glue
all joints. Glue the provided drain trap as shown in fig
ure 47. Route the condensate line to an open drain.
5 - Figure 45 shows the furnace and evaporator coil using
a separate drain. If necessary, the condensate line
from the furnace and evaporator coil can drain togeth
er. See figure. The field provided vent must be a mini
mum 1” to a maximum 2” length above the condensate
drain outlet connection.
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 43.
