For Canadian Installations Proceed
with Steps 1 through 4
Step 1. Attach the cold climate kit, Model
FTF8-CCK1-LD, around the chimney collar with
the screws provided ( see Figure 14 ).
Note: CCK1-LD model requires a 6" diameter
Class 0 metallic air duct, acquired locally by
installer.
Figure 14
Step 2. Connect the 6" (152 mm) Class 0
metallic air duct to the collar on the chimney
collar enclosure with the screws provided in
the hardware kit.
Step 3. Route the Class 0 metallic air duct out
the back wall or side wall, up through the ceiling
or floor joists to an outside wall. The air duct's
inlet should be located above any anticipated
snow level.
Note: If the fireplace is installed against an inside
wall, the Class 0 metallic air duct may be ex-
tended into a ventilated attic space at least 18"
(457 mm) above the attic floor. Secure the duct
hood to a vertical post with the inlet positioned
downward. Ensure that nothing blocks the hood
opening. This air duct must never terminate
higher than the fireplace chimney.
Step 4. Cut or frame a hole through the outside
wall for the installation of the duct inlet hood. A
6 " (165 mm) diameter hole is required. Feed
the loose end of the flexible duct through the
hole cut for the inlet hood and attach to the
collar on inlet hood using two (2) screws. Insert
the hood into the opening. Secure in place with
nails driven through the holes in hood flange.
Seal with noncombustible waterproof silicon
type caulking. If additional air duct is needed,
use Class 0 metallic duct.
