combustion air to one side of the fireplace. Use the model AK4 combustion air kit.

1. Remove the cover plate from the 4" outlet opening location on the left or
right outside of the fireplace.
2. Place the insulation ring between the AK-4 starting collar and fire-
place wall.
3. Place the starting collar (4") into the hole on the side of fireplace. Fasten it in place with the four sheet metal screws
provided. See Figures 20 and 21.
Note: The air starting collar extends through the fireplace outer wrap. When the air starting collar is
securely attached, it will form a seal against the fireplace wall.
4. Attach outside duct to starting collar with duct clamp or screws. See Figure 21.

wall covering where the outside vent is to be located. See
Figure 22.
6. Select and cut a piece of duct long enough to attach to the
fireplace and stick out at least 3" beyond the face of the wall
to which the AK-4 inlet air vent will be attached. Cut duct
with a standard pocket knife. See Figure 21.
Use Fp-4 U duct for maximum efficiency
and safety. Do not use a combustible
duct. Always use UL Listed Class 0 or
1 duct material.
