Outside Combustion Air Controls
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 outside air control 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 36
.
When the complete outside air vent system is
installed, the installer will remove the securing
screw from the combustion air control lever
located on the right side of the fi replace opening.
If the securing screw has not been 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.
