Outside Combustion Air Kit
For use with Wood-Burning and B-Vent Gas Fireplaces
Some homeowners opt to use outside air to supply the flame in their fireplace. The primary reason for this lies in the fact that burning the inside air depletes the indoor oxygen level and can pose a risk. Burning air from the outside ensures that steady heat is available without using up indoor oxygen. This outside combustion air kit from Vantage Hearth allows you to use outside air to heat your home, keeping the oxygen inside at safe levels.
Is there a screen or shield to prevent birds and other small creatures out?
1 Answer
The air intake hood does not include a screen from the factory, but a small bird screen can be easily made and attached to the hood, using 1/8 inch square metal mesh.

This intake air system is configured for use with a 4 inch flexible metal duct. Rigid 4 inch aluminum can also be used if the intake air run is a straight shot to the outside wall.

Where does the outside vent hook to the fireplace and how does the air get into the combustion chamber? Does that interfere with the air circulating from the blower assembly?
1 Answer
On most models, the outside air knockout is located on the right side of the box, although a few models have the inlet on the left.
There is a dedicated air supply tube that runs from the outer wall of the fireplace to directly behind the refractory panels. This tube prevents outside air from mixing with any circulating room air.
