INSTALLATION INSTRUCTIONS

1. Locate air inlet cover plate on ﬁreplace's outer surround and remove

it. Cut-out any visible insulation that may obstruct air ﬂow. Air inlet

tube may be installed in two positions (Figure 2) (AK4E only). In-

sert inner tab of inlet tube into the mating slot next to the opening

(Figure 1). Place outer tab of inlet tube over mating hole next to the

opening and secure with a screw previously removed from cover

plate. Seal any remaining gaps around inlet tube with hi-temp duct

tape or noncombustible sealant (Figure 3 or 4).

2. Construct a 4 1/2" x 4 1/2" framing or opening on exterior wall (see

Figure 3 or 4). Install the outside air vent termination in a location

that would not eventually be obstructed by bushes, snow, or other

obstructions.

Also, locate the vent near the ﬁreplace to make ﬂex duct instal-

lation easier. The ﬂex duct supplied measures approximately 10"

compressed and up to approximately 3 feet extended (Figures 3 or

4).

Be very careful not to distort ﬂex duct when extending and watch for

sharpness at the edges (use gloves). Slip ﬂex duct onto inlet collar

and vent collar. Clean ﬂex duct surface of oil and dirt at the ends

and secure ﬂex duct to collars with hi-temp duct tape to provide a

good seal.
