DAMPER STOP
DAMPER
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.
Creosote, ashes and loose paint must be cleaned from the
chimney fl ue and fi rebox by a qualifi ed chimney cleaner,
before installing in a solid fuel burning appliance.
Any outside air ducts and/or ash dumps in the fi replace shall
be permanently closed at time of appliance installation.
If the damper stop (supplied) is not applicable the damper
may be fi xed open by the following method:
•
Drill a hole in either end of the damper.
• Using a bolt of suffi cient length and adjustment, with 2
nuts, secure to damper through the hole.
