(Note: Drain line can be run horizontally or vertically)
NOTE:
Field Supplied Drain can be routed horizontally from the trap,
allow at least 1/4-in. per foot of slope down.

7. For horizontal left side down:
a. Remove factory-installed collector box cap.
b. Remove the factory-installed cap from the relief port on the trap
and run tube from port on the collector box corner opposite of the
trap to the relief port on the trap (see
). This will require
removing the transducer pressure tubing from the
factory-installed position. If the tube is too long, cut any extra
length from the tube.
c. Install transducer pressure tubing on the collector box port
closest to the trap where the factory-installed collector box cap
was installed (see
). Trim transducer pressure tubing
length ensuring no traps of loops for extra water collections. In
the installed position, the transducer tubing should be in the
lower pressure port and the relief tubing should be in the higher
port.
It is permissible to run the trap up to 5 ft. away from the furnace to an
area with the required trap clearance provided the following steps and
conditions are followed.

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
).
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
). 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 (
).
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
(
).
6. Screw the trap to the adapter plate using provided machine screw
(
). 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
).
NOTICE
!
Extra water in transducer pressure tubing may inhibit furnace operation
because of incorrect pressure readings.
