Figure 6
If your screw is not removed and you have
reason to believe that you have a complete
outside combustion system, contact your dis-
tributor to have your appliance inspected for
the presence of the complete system. DO NOT
assume that you have this system in place
because you have an actuating lever present
on your appliance front face.
WARNING: DO NOT OPERATE THE
COMBUSTION AIR ACTUATOR UNLESS
A COMPLETE OUTSIDE COMBUSTION
AIR VENT SYSTEM HAS BEEN IN-
STALLED WITH YOUR APPLIANCE.
To provide outside combustion air to your
appliance while it is in operation, locate the
combustion air actuator along the right side of
the appliance opening ( refer to Figure 5 ).
To operate, push the end of the actuator to the
left as shown in Figure 6 , 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, en-
sure 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.

MANUALLY-RESET BLOCKED FLUE SAFETY
SWITCH
This appliance is equipped with a manually-
reset blocked flue safety switch. Refer to
Figure 7 for its location. If during appliance
operation, the flame goes out (independently
of the burner on/off wall switch), it may be due
to the operation of this safety limit switch. First
allow the appliance to cool. Then reset the
safety switch by pushing the red reset button
on the back of the switch.
To access the blocked flue safety switch, re-
move the limit switch bracket, with switch and
low voltage wires attached. Push the red reset
button and then reinstall limit switch bracket.
The appliance should then relight and remain
lit. If this does not occur, turn off the appli-
ance and call a qualified service technician.

Maintenance

The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service techni-
cian. Proper maintenance and use will require
more frequent, less extensive inspections and
servicing by the homeowner.
Generally, annual inspections should be per-
formed by a qualified service technician. More
frequent periodic inspections and cleanings
should be performed by the homeowner. Any
discrepancies discovered by the homeowner
should result in a call to a qualified service
technician to effect the repair or correction.
Refer to the maintenance schedule for mainte-
nance tasks, procedures, periodicity and by
whom they should be performed.
IMPORTANT: TURN OFF GAS AND ANY
ELECTRICAL POWER BEFORE SERVICING
THE APPLIANCE.
