•Install as shown in Figures 7.3 - 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.

AK17 Installation (BAY-40)

•Remove the cover plate from the bottom of the ﬁreplace and replace it with outside air plate assembly using existing screws.

•Mark and cut out a 4 1/2 in. (114 mm) diameter hole in the building side for air entry. This hole should allow for some framing (two sides) so the outside air hood assembly may be nailed into position, ﬂush with building’s outside.

•Secure flexible duct (not supplied) to the plate assembly.

•Feed duct through hole to the outside, fasten to the hood assembly.

•Fasten outside air hood assembly to the structure with screws.

Note: To guard against signiﬁcant cold air inﬁltration through duct or other parts of system, check for light leaks with a ﬂashlight and seal these with duct tape and/or insulation.

•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.

•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.

•Assemble ﬂexible duct (not supplied) between the door assembly and the inlet tube assembly. Secure it in position with the supplied wire ties.
