3.10 Combustion Air Duct Pipe
WARNING: Do not use plastic flexible pipe, such as dryer vent pipe, for
combustion air duct pipe venting.
WARNING: Do not terminate combustion air duct pipe into attic or
garage. Termination must be to the outside of the home.
IMPORTANT: Combustion air duct pipes must be secured with screws to
prevent separation and cold air transfer.
NOTE: If the combustion air duct pipe runs for any distance outside
the enclosure, but inside the house, wrap with insulation to eliminate
condensation or frost build-up. See Figure 3.9.
NOTE: If the air intake duct pipe will terminate at the same height or
above the combustion air intake collar on the fireplace, an air trap is
recommended. See venting configurations in Figure 3.10, Combustion
Air Duct Venting Configurations on page 19.
This fireplace requires a supply of outside air for combustion.
The
Albany is manufactured with an combustion air intake collar
protruding approximately 2-7/8” (73mm) out from the right side of
the fireplace. Connect the outside air duct pipe to the combustion air
intake collar and secure with screws.
The combustion air duct pipe termination must be located in an area
so it cannot be blocked (i.e., snow drifts). 4’ (1219mm) above grade is
recommended.
Do not connect outside air pipe until after the fireplace has been
inserted into framing.
Installation instructions continue on the next page.

intake collar after fireplace has been inserted into framing
