OPTIONAL OUTSIDE AIR KIT
(MODEL AK4)
The installation of an outside air kit should be
completed during the rough framing of the fire-
place due to the nature of it's location. Outside
combustion air is accessed through a vented
crawl space.
CAUTION: Air inlet ducts
must not be terminated in an
attic space.
Avoid installing outside air eyebrow in areas where
inlet opening may be blocked by snow, bushes or
other obstacles (see Figure 10).
The maximum height for the air inlet termination
cannot exceed 3 feet below the B-vent termination
exhaust height.
Secure to Collars with Duct Tape or
Screws
