and the "Alternate Vent/Flue Location" figure.
NOTE: Counterflow instructions follow the upflow instructions.
1. Remove and save the four screws securing the vent/flue
coupling to the furnace top panel.
Counterflow units.
1. Remove and save the four screws securing the vent/flue
coupling to the furnace basepan. Also remove the three
screws securing the furnace's internal vent/flue piping to
the blower deck.
2. Upflow and Counterflow units.
Loosen the worm gear hose clamps on the rubber elbow
and detach it from both the induced draft blower and the
vent/flue pipe.
3. Upflow and Counterflow units.
Remove the vent/flue pipe from the furnace.
4. Cut the vent/flue pipe 3.75 inches from the flanged end of
the pipe. See Vent/Flue Pipe Cuts figure. The section of
pipe attached to the coupling will reach through the side
panel to the induced draft blower. Discard remaining pipe
and elbows.
Counterflow units.
Cut the vent/flue pipe 3.75 inches from the blower deck
coupling. See Vent/Flue Pipe Cuts figure. Save vent/flue pipe
attached to blower deck coupling for use in the alternate
location. Discard remaining pipe and elbows.

5. Remove plastic plug from alternate vent/flue location.
Relocate and install plug in standard vent/flue location (top
cover).
Counterflow units.
Remove plastic plug from alternate vent/flue location.
Relocate and install plug in standard vent/flue location
(basepan). Plug remaining hole in blower deck with plastic
plug included in the drain kit bag.
6. Upflow and Counterflow units.
Insert cut section of vent/flue pipe and coupling into alternate
vent/flue location. Using a rubber coupling and worm gear
hose clamps from the drain kit bag, attach the vent/flue pipe
and coupling to the induced draft blower. Secure the
coupling to the cabinet using the screws removed in step 1
or with field-supplied 3/8" #8 self drilling screws.

Secure 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 be installed on the same side of the unit as the flue
pipe.
8. Upflow and Counterflow units.
For horizontal installations, externally secure the field-
supplied vent/flue pipe directly to the vent/flue coupling using

ON IRECT ENT
Non-direct vent installations require only a vent/flue pipe. The vent
pipe can be run horizontally with an exit through the side of the
building or run vertically with an exit through the roof of the building.
The vent can also be run through an existing unused chimney;
however, it must extend a minimum of 12 inches above the top of
HEN
the chimney. The space between the vent pipe and the chimney
must be closed with a weather-tight, corrosion-resistant flashing.
