Horizontal
Orientation
When the furnace is installed in the horizontal right position, the
condensate trap will be initially located at the bottom of the
collector box, as received from the factory. See the top image in
. When the furnace is installed in the horizontal left
position, the condensate trap will be initially located at the top of
the collector box, as received from the factory. See the top image
in
. In both cases trap must be repositioned on the
collector box for proper condensate drainage. See bottom images

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
)
NOTICE
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 ventil-
ated combustion air venting.
NOTICE
The condensate trap extends below the side of the casing in
the horizontal position. A minimum of 2-in. (51 mm) of clear-
ance is required between the casing side and the furnace
platform for the trap to extend out of the casing in the hori-
zontal position. Allow at least 1/4-in. per foot (20mm per
meter) of slope down and away from the furnace in horizontal
sections of drain line.
NOTE
: 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. (6 mm) per foot of slope away
from the furnace in horizontal sections of drain line.
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.

from relief port on
condensate trap.
Remove middle and right
plug from collector box.
DO NOT DISCARD
Remove relief tube
from port on collector
box.
