CAUTION: NEVER LOCATE INLET WHERE IT
CAN BE BLOCKED BY SHRUBS, SNOW
DRIFTS, ETC. NEVER LOCATE INLET IN GA-
RAGE OR ANY AREA WHERE THERE IS AN-
OTHER FUEL BURNING APPLIANCE OR PROD-
UCTS EMITTING COMBUSTIBLE GASES SUCH
AS PAINT, GASOLINE, ETC. IN COLD CLI-
MATES, IT IS RECOMMENDED THE COMBUS-
TION AIR DUCT BE INSULATED.
Outside combustion air ducting may be run
upwards or vertically through framing and ceil-
ing joists, with the hood installed through an
outside wall and 3' (1 m) below the termination.
Ducting may also be run downward through
floor joists and under the home to a ventilated
crawlspace not considered part of the living
area of the home.
After installing the outside air kit, remove the
cover from the shut off lever in the left side of
the firebox opening.
Note: Do not terminate combustion air kit in
attic space under any circumstances.
After completing the installation of the optional
combustion air vent system the actuator arm
must be put in service and tested to ensure
proper operation before completing any enclo-
sure around the firebox. Failure to do so may
result in extensive and costly rework.
Operate the actuator through several cycles
including the closed position. Ensuring proper
operation and freedom of movement. Return
the actuator arm to the closed position.
Step 8. Installing Logs and Rockwool – The
logs are packaged within the firebox. The bag of
rockwool is in the lower control compartment.
Remove the rockwool from the packaging and
tear into dime size pieces (see Homeowners Care
and Operation Instructions). Do not use more
than is necessary.
