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.
T
HE RUBBER ELBOW IS NOT DESIGNED TO SUPPORAT A LOAD.
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.
7. Upflow and Counterflow units.
For upright installations, externally mount the rubber elbow
to the vent/flue coupling using a worm gear hose clamp.
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
a PVC or ABS coupling or elbow.

The alternate combustion air intake location consists of a large,
unobstructed hole (alternate vent connection is aligned with the
Induced Draft Blower). To use the alternate combustion air intake
location, refer to the following steps, and the "Alternate Combus-
tion Air Intake Location" figure.
NOTE: Counterflow unit instructions follow the upflow instructions.
HEN THE
1. Remove and save the four screws securing the combustion
air intake coupling to the furnace's top panel (upflow).
Counterflow units.
Remove and save the four screws securing the combustion
air intake coupling to the basepan. Remove an additional
three screws securing the furnace's internal combustion air
intake pipe to the blower deck.
2. Remove the combustion air intake coupling and gasket from
the top panel.
Counterflow units.
Remove the combustion air intake pipe from the furnace and
cut the pipe at the basepan coupling. Save the basepan
coupling and gasket from the blower deck coupling for use
in the alternate location. Discard the remaining pipe.
3. Remove plastic plug from alternate combustion air intake
location. Relocate and install plug in standard air intake
location (top cover).
Counterflow units.
Remove plastic plug from alternate combustion air intake
1
location. Relocate and install plug in standard air intake
location (basepan). Plug the remaining hole in the blower
deck with the plastic plug included in the drain kit bag.
4. Upflow and Counterflow units.
With the gasket facing the cabinet side panel, and the flange's
2 flat spot facing forward, secure the combustion air intake
coupling to the cabinet using the screws removed in step 1
or with field-supplied 3/8" #8 self -drilling screws.
B
E SURE NOT TO DAMAGE INTERNAL WIRING OR OTHER COMPONENTS WHEN
REINSTALLING COUPLING AND SCREWS.
5. Upflow and Counterflow units.
For non-direct vent installations installed horizontally, a
minimum of one 90° elbow should be installed on the
combustion air intake coupling to guard against inadvertent
blockage. No elbow is required on the alternate combustion
air intake of upright installations, however, a minimum
clearance of 2 inches is required to assure proper air supply.
6. Upflow and Counterflow units.
For direct vent installations, secure field-supplied
combustion air intake pipe directly to the air intake coupling.
NOTE: A PVC coupling or elbow is required on counterflow
units.
