Risk of Smoke Spillage
Outside air inlet must be located to prevent blockage
from:
• Leaves
• Snow/ice
• Other debris
Blockage may cause combustion air starvation.
CAUTION
Sharp Edges
• Wear protective gloves and safety glasses
during installation.

Do not draw outside combustion air from:
• Wall, fl oor or ceiling cavity.
• Enclosed space such as an attic or

• Close proximity to exhaust vents or
chimneys.
Fumes or odor may result.

Figure 4.1 Outside Air Installation
A. Install the Outside Air Kit
This fi replace will operate correctly only if adequate ventila-
tion is provided to allow proper draft to the fi replace system.
See Section 2.
Using an outside air kit is highly recommended to minimize
the effects of negative pressure within the structure. We
recommend you utilize the shortest duct run to optimize the
performance of the outside air kit. Cold air fl ow can be mini-
mized by putting a small dip in the duct creating a cold air
trap. This trap can also help prevent heat build-up and ex-
hausting out the intake due to the stack effect. The outside
air kit inlet should be positioned in a manner that will not al-
low snow, leaves, etc. to block the inlet. In some installations
the air duct may need to be run vertically. In such an instal-
lation, a 3 ft (.914 m) height difference must be maintained
from the top of the uppermost chimney section to the outside
combustion air inlet. See Figure 4.2.
See Figure 4.3 for proper placement of outside air inlet.
The outside air kit is installed on the left hand side of the
fi replace. See Figure 4.4 for handle location/operation.
