Remote Trap Installation Specific Steps
1. The trap can be installed using a second adapter plate purchased
separately.
Install trap adapter to the collector box using provided machine
screw (see Fig. 14).
2. Screw the adapter plate to the side of casing using six (6) of the
provided sheet metal screws (see
3. Screw the adapter plate to the trap adapter using provided machine
screw (see Fig. 23). Drilling pilot holes is recommended to better
align the plate with the knockout opening.
4. Install the second trap plate at the remote location, 5 ft. or less away
from the furnace (Fig. 23).
5. Using two field supplied 1/2-in. CPVC tubes of the desired length
(5 ft. or less) and 2 field supplied CPVC elbows, run the drain from
the adapter plate on the furnace to the remote adapter plate
(Fig. 23).
6. Screw the trap to the adapter plate using provided machine screw
(Fig. 23). Ensure trap is firmly secured and supported.
7. Follow steps 6 and 7 in the above section, Horizontal Specific
Steps, for the proper routing of pressure tubing depending on
furnace orientation. Substitute the relief port on the trap adapter for
the relief port on the trap in remote trap installations. The
factory-installed cap over the relief port on the trap should remain
in place. Tubing should remain inside the furnace.

Condensate Drain Connection
1. Use of the condensate drain elbow in the loose parts bag is required
to make a connection to the field supplied drain.
2. Remove the pre-formed rubber drain elbow, and two spring clamps
from the loose parts bag.
3. Connect the full elbow to the outlet of the condensate trap with one
spring clamp. Avoid misalignment of the drain pipe which may
cause kinks in the elbow or grommet (See
4. The remaining drain line can be constructed from field- supplied
1/2-in. CPVC or 3/4-in. PVC pipe, in compliance with local
building codes. A factory-supplied 1/2-in. CPVC to 3/4-in. PVC
adapter is supplied in the loose parts bag for use as required.
5. Install the adapter or connect the 1/2-in. CPVC pipe by sliding a
spring clamp over the open end of the elbow or grommet on the
outside the furnace casing.
6. Open the spring clamp and insert the long end of the adapter or the
1/2-in. CPVC pipe into the outlet stub on the drain tube (See
Fig. 24).
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

7. Connect additional condensate piping to a code-approved drain, or
to a condensate pump approved for use with acidic furnace
condensate and compatible with mineral and vegetable oils, such as
canola oil.
8. Allow at least 1/4-in. per foot (20 mm per meter) of slope down and
away from the furnace in horizontal sections of drain line.

Installation of Evaporator Coils
When installing the evaporator coil, refer to the allowed installation
configurations (Table 7). Some coils require an 8-in. tall sheet metal
spacer between the furnace and the coil or some require a metal shield
between the drain pan of the coil and the discharge flanges of the
furnace. This is to protect the composite drain pan of the evaporator coil.
The coil offset adapter kits in the product accessory list will require an
additional field fabricated adapter to ensure the 8-in. separation.
!
FIRE HAZARD
When installing evaporator coils that have composite (plastic) drain
pans and are exposed directly to the furnace heat exchanger, a sheet
metal spacer/transition or drain pan shield is required.
Failure to protect the coil composite drain pan could result in fire,
personal injury, or death. (Table
Table 7 – Evaporator Coil Spacer or Shield Requirements.
