trap
A11348
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
.
In areas where the ambient temperature will fall below
32
°
F. (0
°
C), a field
−
supplied condensate freeze protection kit is
required. See Product Data for current kit offering. Follow the
instructions included in the kit.
To Relocate the Condensate Trap:
1. Remove the knockout in the casing for the casing
grommet.
2. Install the grommet in the casing.
NOTE
: This grommet is only required for direct
−
vent
applications.
3. Orient the furnace in the desired position.
4. Allow for 2
−
in. (51 mm) of clearance underneath the
furnace for the condensate trap and drain line.
5.
Figure 10
shows the condensate trap and tubing before
and after relocation in the horizontal left position.
6.
Figure 11
shows the condensate trap and tubing before
and after relocation in the horizontal right position.
7. Refer to the appropriate figure to begin the trap
conversion.
8. Remove the relief tube from the condensate trap.
9. Remove the screw that secures the condensate trap to
the collector box.
10. Remove the trap.
Horizontal Left only:
1. Remove the relief tube from of the port on the collector
box. It is not necessary to remove the hose from the
inducer assembly.
2. Remove the pressure switch tube from the port on the
collector box.
3. Remove the pressure switch tube from the stand
−
offs on
the inducer assembly.
For Horizontal Right only:
1. The pressure switch tube location is not modified.
2. Loosen the clamp around the inlet of the vent elbow on
the inducer.
3. Remove the plugs from the collector box and set aside.
Do Not Discard Plugs
.
For Horizontal Left only:
1. Remove the middle and right plug from the ports at the
bottom of the collector box.
For Horizontal Right only:
1. Remove the plug to the right of the condensate trap.
2. Refer to the appropriate figure to begin the trap
conversion.
3. Install the plugs previous removed from the collector box
in the ports where the condensate trap was removed.
4. Install the trap over the ports on the lower side of the
collector box.
5. Secure the trap to the collector box with the screw.
6. Connect the relief tube to the condensate trap to the
relief port of the condensate trap.
7. If necessary, slide the relief tube in the inducer
stand
−
offs to adjust the position of the tube.
For Horizontal Left only
:
1. Connect the relief tube to the relief port of the
condensate trap.
2. Connect the pressure switch tube to the port on the
collector box next to the condensate trap. Trim off any
excess tube to avoid sags or kinks in the tube.
3. Rotate the vent elbow to the desired position and tighten
the clamp 15 in.

4. Refer to Condensate Drain section for information how to
install the condensate drain.
