INSTALLATION INSTRUCTIONS
Install the two plugs
previously removed
on the open ports
of the collector box.
Connect relief tube
to port on collector
box.
Rotate elbow to
desired position
and
tighten clamp to
15 lb.−in.
Slide tube in stand−offs
4
to adjust length.
Condensate Trap − 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
Figure 10. 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 Figure 11. In both cases the trap must be repositioned on the
collector box for proper condensate drainage. See bottom images
in Figure 10 and Figure 11.
A field−supplied, accessory Horizontal Installation Kit
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
Figure 16)
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 ventilated combustion air venting.

Specifications subject to change without notice.
Attach condensate trap
with screw to collector box.
5
Align condensate trap
over middle and bottom
ports of collector box.
NOTICE
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 (20mm per meter) of slope down and
away from the furnace in horizontal sections of drain
line.
To Relocate the Condensate Trap:
S
Remove the knockout in the casing for the condensate trap.
S
Install the grommet in the casing when required for direct−vent
horizontal applications.
S
Orient the furnace in the desired position.
S
Allow for 2 in. (51 mm) of clearance underneath the furnace for
the condensate trap and drain line.
S
Figure 10 shows the condensate trap and tubing before and
after relocation in the horizontal right position.
S
Figure 11 shows the condensate trap and tubing before and
after relocation in the horizontal left position.
S
Refer to the appropriate figure to begin the trap conversion.
S
Refer to Condensate Drain section for information how to install
the condensate drain.
Gas Furnace: (F/G)9MVE
Route tube through inducer
stand−offs to adjust position
of the tube.
Trim excess tube.
Connect pressure switch
tube to port on collector
box.
Connect relief tube to
relief port on condensate
trap.
