DAMPER AND COMbUSTION AIR CONTROLS
This appliance is fitted with a manually controlled
vent damper. The vent damper should be closed
when the appliance is not in use to prevent cold
air from entering the home through the venting
system. The damper is controlled through the
use of a control lever located within the appli-
ance opening at the top center in front of the
firebox lintel
(see
Figure 6
)
.
The control lever snaps into place at either
extreme of its range of motion. When locked
in position all the way to the right, the damper
is open. When locked in position all the way
to the left, the damper is closed.
The damper lever actuates a switch, (see wiring
diagram) which will prevent the appliance main
burner from lighting unless the damper is locked
open. The appliance flue damper must always
remain open when operating.
WARNING
Only doors certified with the
appliance shall be used.

Many appliances are equipped when installed
with an outside (make-up) air vent system that
is designed to provide the appliance with outside
make-up air for combustion when in operation.
The actuator for the outside air system is stan-
dard on all appliances but must not be operated
if the complete system is not installed. Refer to
Figure 5
.
When the complete outside air vent
system is installed, the installer will remove the
actuator locking screw.
If your screw is not removed and you have
reason to believe that you have a complete
outside air system, contact your distributor 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.
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, 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.
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
(
Figure 6
)
.
WARNING
Do not operate the shutoff lever
unless a complete outside air
vent system has been installed
with your appliance.
WARNING
Damper must be in open position
when appliance main burner is
operating.
