*The illustration provided is a simple outside are installation. Your installation may vary significantly but try to keep the
hose length to no more than 20 feet in length to provide sufficient air flow. Keep the inlet air vent level or below the
firebox entry if possible.
• Never terminate the “inlet air vent” in a garage.
• Make sure the “inlet air vent” is located in an area
which is free from snow build-up and dense bushes.
1. Place the insulation gasket between the open air kit
starting collar and fireplace wall.
2. Place the starting collar (4”) on the side of fireplace.
Fasten it in place with the four sheet metal screws provided.
NOTE: When the air starting collar is securely attached,
it will form a seal against the fireplace wall.
3. Attach outside duct to starting collar with duct clamp or screws.
4. Cut a 6-inch diameter opening for the open air kit in the
outside wall covering where the outside vent is to be located.
5. Select and cut a piece of duct long enough to attach
to the fireplace and stick out at least 3” beyond the
face of the wall to which the open air kit inlet air vent
will be attached. Cut duct with a standard pocket knife.
6. If the duct is the insulated type, push the insulation
back from one end of the duct approximately 2”.
7. Slip the exposed end of the duct over the starting
collar on the fireplace.
8. Using the sheet metal screws provided, secure the
duct end to the collar attached to the fireplace.
9. Nail or screw the combustion air assembly to the
surface of the wall.

Do not use a combustible duct. Always use UL Listed Class 0 or 1 duct material.
