Alternate Combustion Air Intake Location

The alternate combustion air intake location is the large
hole not in line with the induced draft blower outlet. To use
the alternate combustion air intake location, refer to the
following steps, and the "Alternate Combustion Air Intake
Location" figure.
NOTE: Counterflow unit instructions follow the upflow
instructions.
1. Remove and save the four screws securing the com-
bustion air intake coupling to the furnace's top panel
(upflow).
Counterflow units.
Remove and save the four screws securing the com-
bustion 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 fur-
nace 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.

With the gasket facing the cabinet side panel, and the
flange's 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.
CAUTION
Be 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 horizon-
tally, a minimum of one 90° elbow must 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:
counterflow units.
