Figure 17
Locate the actuator arm along the right side
of the appliance firebox opening and refer to
Figure 17. After completing the installation
of the Outside Combustion Air Kit remove and
discard the actuator arm locking screw.
To operate, push the end of the actuator to
the left as shown in Figure 17, 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 actua-
tors to the right until the step in the actuator
moves behind the appliance front face within
the slotted opening.
Operate the actuator through several cycles
including the "lock" position. Ensuring proper
operation and freedom of movement. Return
the actuator arm to the locked position.
Step 7. Install (Optional) Outside
Air Kit
These appliances are equipped with an out-
side (make-up) air door and integral actuator
arm. If the appliance is to be installed with
an outside air vent system, use only Lennox
Hearth Products 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.

CAUTION
Never locate inlet where it can be
blocked by shrubs, snow drifts,
etc. Never locate inlet in garage
or any area where there is another
fuel burning appliance or products
emitting combustible gases such
as paint, gasoline, etc. In cold
climates, it is recommended the
outside air duct be insulated.
Step 8. Install Logs and Glowing
embers
The logs are packaged and boxed within the
firebox. The bag of glowing embers is in the
lower control compartment. Remove the glow-
ing embers from the packaging and tear into
quarter size pieces (see the Care and Operation
Instructions).
Carefully position the ceramic fiber log assembly
onto the burner, refer to the Care and Opera-
tion Instructions for detailed log description
and placement instructions. Position the logs
onto the pins of the burner, with the cutouts
fitted around the burner tube. Ensure the rear
log matches the cutout on its bottom with the
position of the pilot.
WARNING
• DO NOT attempt to install the
logs until the appliance instal-
lation has been completed, the
gas line connected and tested
for leaks and the initial burner
operation has been checked
out.
• The size and position of the log
set was engineered to give the
appliance a safe, reliable and
attractive flame pattern. Any
attempt to use a different log
set in the fireplace will void
the warranty and will result in
incomplete combustion, soot-
ing, and poor flame quality.
• Logs get very hot and will
remain hot up to one hour
after gas supply is turned off.
Handle only when logs are
cool. Turn off all electricity
to the appliance before you
install grate and logs.
• This appliance is not designed
to burn wood. Any attempt to
do so could cause irreparable
damage to the appliance and
prove hazardous to your safety.
• If logs are not installed
according to the log instal-
lation instructions, flame
impingement and improper
combustion could occur and
result in soot and/or excessive
production of carbon monoxide
(CO), a colorless, odorless,
toxic gas.
