INSTALLING IN A VENTED APPLICATION

The appliance and gas logs function as a system. If the appliance is not drafting properly and spilling into the
room (check with a match or a smoke stick), reposition the damper clamp until a positive draft is obtained by
opening the damper. If negative pressure in home prevents having a positive draft, consult an air quality spe-
cialist.

3.2.1 DAMPER STOP INSTALLATION

BEFORE INSTALLING IN A SOLID FUEL BURNING FIREPLACE, THE CHIMNEY AND FIREBOX MUST BE
CLEANED OF SOOT, CREOSOTE, ASHES, AND LOOSE PAINT BY A QUALIFIED CHIMNEY CLEANER.
The damper must be permanently locked in
position to prevent full closure and to provide
a minimum fl ue opening. Various methods
for locking the damper may be used but may
be restricted from region to region and it is
important to know the specifi cs that apply to
your area. For your convenience a damper stop
is provided with the appliance and may be used
where not prohibited by state or local codes.
Use the 3" adjustable bolt to adjust the damper to the
correct opening, based on the enclosed chart.
Should the damper stop not fi t, or provide the required
permanent opening from the Minimum Damper Opening
table, have the damper cut to provide a minimum
permanent opening or install an alternate stop.
Any outside air ducts and/or ash dumps in the appliance
shall be permanently closed at time of appliance
installation.
