3.3 dAmpeR Stop INStALLAtIoN
The damper must be permanently locked in
position to prevent full closure and to provide a
minimum flue 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 specifics 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" (72.6mm) adjustable bolt to adjust
the damper to the correct opening, based on the
enclosed chart.
Should the damper stop not fit, or provide the required permanent opening (see "Minimum Damper Opening
Chart"), 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 flue and firebox by a qualified chimney
cleaner, before installing in a solid fuel burning appliance. Any outside air ducts and / or ash dumps in the
fireplace shall be permanently closed at time of appliance installation.
If the damper stop (supplied) is not applicable the damper may be fixed open by the following method:
• Drill a hole in either end of the damper.
• Using a bolt of sufficient length and adjustment, with 2 nuts, secure to damper through the hole.
• Adjust to correct opening.
