Completion of Air Kit installation
1. Determine the length of 4” Dia. rigid or flex duct connector
(installer supplied) you will need from the firebox/fireplace
to the exterior surface of the outside wall, where the air kit
hood will be installed. Add a few extra inches to the length
to allow for easier attachment of the outside duct connection
prior to securing the outside rain cap hood to the building.
2. Secure the 4” dia. duct to the Air Door assembly collar on the
firebox/fireplace with band clamps or screws.
3. Run the other end of the duct through the exterior wall cut-
out.
4. From the outside of the building, connect the duct to the
collar on the outside air vent assembly with band clamp or
screws to secure.
5. Mate the outside rain cap hood over the air vent, seal with
caulk as necessary, then secure with screws provided to the
exterior wall surface. See
Figure 22 and 23.
