Condensate Trap-Horizontal Orientation
When the furnace is installed in the horizontal right position, the
condensate trap will be initially located at the bottom left corner of the
collector box, as received from the factory. See the top image in

trap must be repositioned on the collector box for proper condensate
drainage. See the bottom images in
A field-supplied, accessory Horizontal Installation kit (trap grommet) is
required for all direct-vent horizontal installations (only). The kit
contains a rubber casing grommet designed to seal between the furnace
casing and the condensate trap, see
If alternate vent position
is required, loosen clamp
on vent elbow inlet.
Remove relief tube
from port on collector
box.

As Viewed in the Horizontal Left Orientation
Rotate elbow to
desired position and
torque clamp on inlet

Slide relief tube in
stand-offs to adjust
length.
Attach condensate
trap to collector box
with screw.
Align trap over middle
and right-hand port on
collector box.
Horizontal Left Trap Configuration

(Appearance May Vary)
To Relocate the Condensate Trap:
• Remove the knockout in the casing for the condensate trap.
• Install the grommet in the casing when required for direct-vent
horizontal applications.
• Orient the furnace in the desired position.
• Allow for 2 in. (51 mm) of clearance underneath the furnace for the
condensate trap and drain line.
• Fig. 10 shows the condensate trap and tubing before and after
relocation in the horizontal right position.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

Horizontal Right Trap Configuration
Fig. 10 – Horizontal Right Trap Configuration
The condensate trap extends below the side of the casing in the
horizontal position. A minimum of 2-in. (51 mm) of clearance is
required between the casing side and the furnace platform for the trap to
extend out of the casing in the horizontal position. Allow at least 1/4-in.
per foot (20 mm per meter) of slope down.
The field-supplied, accessory horizontal drain trap grommet is ONLY
REQUIRED FOR DIRECT VENT APPLICATIONS. It it NOT
required for applications using single-pipe or ventilated combustion air
venting.

PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in burst water pipes and/or
property damage.
If a condensate pump is installed, a plugged condensate drain or a failed
pump may cause the furnace to shut down. Do not leave the home
unattended during freezing weather without turning off water supply
and draining water pipes or otherwise protecting against the risk of
frozen pipes.
