DAMPER AND OUTSIDE 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 5). 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
Do not operate the shutoff lever
unless a complete outside air
vent system has been installed
with your appliance.

Figure 5
The appliance is equipped 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 shut-
off lever for the outside air system is standard
on all appliances but should not be operated
if the complete system is not installed. Refer
to Figure 5. Outside air kits are not required
in all municipalities and may not be installed
or active with your appliance.
If you have reason to believe that you do
not have a complete outside air system, con-
tact your distributor to have your appliance
inspected for the presence of the complete
system. DO NOT assume that you have this
system in place.
The hand operated shut-off lever is located in
the right side of the fireplace opening behind
the screen. To open, lift and pull all the way.
The outside air damper should be open when
the fireplace is in use and completely closed
when the fireplace is not being used. This
will prevent outside cold air from entering
the dwelling.
