performed during the rough framing of the fire-
place due to the nature of it’s location. Outside
combustion air is accessed through and exterior
wall (AK4) or a vented crawl space (AK4F). See

where inlet opening may be blocked by snow,
bushes or other obstacles. It should also be
located beyond the reach of children.

not terminate in attic space or
garage.
The maximum height for the
air vent can not exceed 3 feet
below the flue gas outlet of the
termination.
For further details on installation of outside air
kit, please refer to instructions included with
