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.

Locate the outside air hood 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 hood 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 hood 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.

AK14/AK18 Installation

The hinge will be toward the front of the fireplace.

Insert the narrow end of the handle into the upper slot.

Pivot the handle in the slot toward the hinge.

Remove the cover plate or knockout from the side of the fireplace and discard. Remove the semi-perforated piece of insulation covering the opening (insulated fireplaces only).

Partly open the air kit door and insert the handle into the appropriate hole in the side column of the fireplace. The hinge on the door assembly should be located toward the front of the fireplace. If the hinge and the handle are not positioned in this manner, the door will not function correctly.

Attach the door assembly to the fireplace using the screws provided.

Check operation by pulling the handle out to open and pushing it in to close.

Mark and cut out a 4 1/2 in. (114 mm) hole in the building side for air entry. This hole should allow some framing (two sides) so the 4 in. (102 mm) diameter inlet tube assembly may be fastened properly.
