Outside Combustion Air Kit remove and discard
the actuator arm locking screw.
To operate, push the end of the actuator to the

, until it "pops" free
of its "locked" position. Pull the actuator
forward to open the combustion air door, and
push it back to close. To "lock" the combustion
air door closed, ensure the actuator is pushed
all the way back then push the end of the
actuators to the right until the step in the
actuator moves behind the appliance front
face within the slotted opening.

Step 7. Installing Outside Air Kit – These
appliances are equipped with an outside (make-
up) air door and integral actuator arm. If the
appliance is to be installed with an outside air
vent system, use only Lennox Models FAOK-4
or FAOK-4LD Combustion Air Kits.
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.
