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 flow 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 fireplace. See Figure 4.4 for handle location/operation.

CAUTION

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.
