INSTALLING AN OUTSIDE AIR KIT IN A CHASE:
1. If the chase is framed first, a minimum width of 1197mm (47-1/8") is required. A minimum width of 1146mm
(45-1/8") can be used if the chase is to be framed later.
2. Cut the duct to about 760mm (30") for a 610mm (24") deep chase.
3. Flatten the aluminum inner so the reduced hood assembly will fit. Cut the hood assembly down to approximately
125mm (5") length.
4. Cut a hole in the back wall (drywall) approximately 127mm (5") in diameter and in the outside wall approximately
89mm (3-1/2") in diameter.
5. Attach the duct to the outside air stub using the two screws provided.
6. Carefully shift the fireplace into place, while doing this pull the duct through the back wall and attach the hood
assembly with the remaining 2 screws provided.
7. Seal and fasten the hood assembly to the outside wall using a suitable caulking and the 3/4" screws provided.
