Damper Stop Installation
When installing a decorative gas appliance in a fire-
place, some local codes require a damper stop be
added so the damper will not close completely. The
CFM Corporation damper stop is designed so the
damper can be locked in the closed position, and still
allow a vent for the pilot gasses.
This damper stop is designed to work on all CFM Cor-
poration BR, BC, SR, SC, TF and TL series fireplaces.
Installation Instructions
1. Open damper. The damper must be open to attach
the damper stop.
2. Locate the damper locking bracket. From inside the
fireplace locate the damper locking bracket on the
left side of the combustion dome. (Fig. 4)
3. Align the two slots on either side of the cutout on the
damper stop with the two small holes on the angled
portion of the damper locking bracket. Attach the
damper stop with the screws provided. (Fig. 5)
NOTE: Some of the early units may not have the holes
in the end of the damper locking bracket. If this is the
case use the damper stop as a template to drill two (2)
1/8” holes in the damper locking bracket to mount the
damper stop.
