3. Remove the vent/flue pipe from the furnace.
4. Cut the vent/flue pipe 3³⁄₄" (9.5 cm) from the flanged end of
the pipe. See "Vent/Flue Pipe Cuts" illustration.
NOTE: The section of pipe attached to the coupling will reach
through the side panel to the induced draft blower.
5. Discard remaining pipe and elbows.

6. Remove the plastic plug from the alternate vent/flue location.
7. Relocate and install the plastic plug in the standard vent/flue
location (top cover).
8. Insert the cut section of the vent/flue pipe and coupling into
the alternate vent/flue location.
9. Attach the vent/flue pipe and coupling to the induced draft
blower using a rubber coupling and worm gear hose clamps
provided in the drain kit bag.
10. Secure the coupling to the cabinet using the screws removed
in Step 1 or with field-supplied ³⁄₈" #8 self-drilling screws.
WARNING
The rubber elbow is not designed to support a load.
Goodman 57
When the rubber elbow is mounted externally to the
furnace cabinet, extreme care must be taken to adequately
support field-supplied vent/flue piping, as damage can
result in leaks causing bodily injury or death due to
exposure to flue gases, including carbon monoxide.
11. For upright installations, externally mount the rubber elbow to
the vent/flue coupling using a worm gear hose clamp.
12. Secure the field supplied vent/flue piping to the rubber elbow
using a worm gear hose clamp.
NOTE: Use of the alternate vent/flue location for upright
installations, requires the drain trap to be installed on the
same side of the furnace as the flue pipe.
13. For horizontal installations, externally secure the field
supplied vent/flue pipe directly to the vent/flue coupling using
a PVC or ABS coupling or elbow.

1. Remove and save the 4 screws securing the vent/flue
coupling to the furnace base pan.
2. Remove the 3 screws securing the furnace's internal vent/flue
piping to the induced draft blower deck.
3. Loosen the worm gear hose clamps on the rubber elbow and
detach the rubber elbow from both the induced draft blower
and the vent/flue pipe.
4. Remove the vent/flue pipe from the furnace.
5. Cut the vent/flue pipe 3³⁄₄" (9.5 cm) from the induced draft
blower deck coupling. See "Vent/Flue Pipe Cuts" illustration.
6. Save the vent/flue pipe attached to the induced draft blower
deck coupling for use in the alternate location.
7. Discard remaining pipe and elbows.
