NOTE: Remove Inducer Housing for easier access, if desired.
Fig. 16 – Drain Trap Connection and Routing
(Appearance may vary)
Assemble and route the drain line to the opposite side of the furnace as
detailed below:
5. Remove the inducer housing screws, disconnect harnesses, and set
inducer housing aside. See
removal technique.
6. Remove condensate trap.
7. Remove 7/8-in. knockout or plug from the left side of the casing.
See Fig. 15 for suggested knockout or plug removal technique.
8. Starting from inside the casing, pull the grommet through the hole
until it is seated in the hole.
9. Assemble the Z-pipe, rubber elbow and condensate trap external to
the unit by securing the rubber elbow to the drain trap and the
Z-pipe with spring clamps.
10. Slide the spring clamp for the Z-pipe/grommet connection over the
Z-tube.
11. Adjust the Z-pipe orientation prior to final installation to ensure the
Z-pipe will be as horizontal as possible and NOT resting on any
sheet metal parts.
12. Align the Z-pipe with the long end of the grommet inside the
furnace and insert slightly. The angled end of the tube at the other
side of the casing should be facing the front of the furnace.
13. Slide a spring clamp over the end of the remaining rubber drain
elbow.
14. Re-attach the condensate trap with Z-pipe assembly. Make fine
adjustments to the Z-pipe orientation as needed to ensure the Z-pipe
is as horizontal as possible. Condensate trap screws should be
torqued to 17.5 +/- 2.5 in-lbs. Do NOT use power tools and torque
to a maximum of 20 in-lbs.
15. In both upflow and downflow orientations, the Z-pipe should NOT
be resting on any sheet metal parts.
16. Replace inducer housing. Inducer housing screws should be
torqued to 17.5 +/- 2.5 in-lbs. Do NOT use power tools and torque
to a maximum of 20 in-lbs.
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.
17. Install the adapter or connect the 1/2-in. CPVC pipe by sliding a
spring clamp over the open end of the grommet on the outside the
furnace casing.
18. 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.
19. 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.
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.
The field-supplied, accessory horizontal drain trap grommet is ONLY
REQUIRED FOR DIRECT VENT APPLICATIONS. It is NOT
required for applications using single-pipe or ventilated combustion air
venting.

TIP FROM CONTRACTORS: When installing the furnace
horizontally, use the entire drain elbow (that is, do NOT cut as shown in
Fig. 17 to connect the trap to the drain line. This helps to prevent bumps
and shocks to the drain line from damaging the furnace drain trap. Avoid
misalignment of the drain pipe which may cause kinks in the elbow.

Horizontal Orientation
1. The condensate trap outlet extends 2-in. (51 mm) below the furnace
casing. Leave enough clearance between the furnace and the
furnace platform for the trap.
2. To allow for servicing the trap, the condensate drain elbow in the
loose parts bag can be used to make a coupler to allow for future
service of the condensate trap and drain line.
3. Remove the knockout or plug for the condensate trap in the side of
the casing.
4. Install the drain trap grommet in the casing if required for
direct-vent applications. If necessary, remove the trap, install the
grommet and re-install the trap.
5. Remove the pre-formed rubber drain elbow, and two spring clamps
from the loose parts bag.
6. Connect the full or modified elbow and/or grommet 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.
7. 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.
8. 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.
9. 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.
10. 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.
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.
