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).

Upflow and Counterflow Units
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

" #8 self-drilling screws.
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.

The rubber elbow is not designed to support a load.
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.
