E. Install Outside Air Kit

Keep duct runs short and straight to minimize restriction. A small dip is acceptable for a cold air trap.

The outside air kit must be installed on the left hand side of the fireplace.

Locate the air inlet in a clear area, preferably into prevailing wind during the heating season. Refer to Figure 5.2.

Install as shown in Figures 7.3, 7.4 and 7.5.

The air duct may be run vertically.

The outside air inlet must be at least 3 ft (.91 m) below the top of the uppermost chimney section.

CAUTION! Risk of Fire or Asphyxiation! DO NOT draw outside combustion air from wall, floor or ceiling cavity, or enclosed spaces such as an attic or garage.

DO NOT place outside air inlet close to exhaust vents or chimneys. Fumes or odor could be drawn into the room through the fireplace.

Locate outside air inlet to prevent blockage from leaves, snow/ice, or other debris. Blockages could cause combustion air starvation.
