For Use with BR, BC, SR, SC, TF and TL Series CFM
Corporation Fireplaces
This Damper Stop is designed to work on all CFM Corpora
-
tion BR, BC, SR, TF and TL series fireplaces. For all other
fireplaces, refer to note bellow.
When installing a decorative gas appliance in a fireplace,
some local codes require this Damper Stop to be used so
the Damper will not close completely. To install the Damper
Stop:
The Damper Locking Bracket is already installed on all BR,
BC, SR, TF and TL fireplaces. Locate the Damper Locking
Bracket on the left side of the fireplace’s Combustion Dome.
(Fig. 1)
With the Damper open, align the two slots on either side
of the cut-out on the Damper Stop with the two small holes
on the angled portion of the Damper Locking Bracket. At
-
tach the Damper Stop with the Screws provided, as shown
in Figure 2.
NOTE: Some of the early fireplace 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.
For Use With All Other Fireplaces
The Damper Clamp provided keeps your damper from ac
-
cidentally closing during operation of your set. This Damp
-
er Clamp must be installed onto your Damper at all times.
NOTE: The damper clamp is designed to hold the damper
plate open inches. However, the damper must be fully
open when the log set is in operation.
Install the Damper Clamp onto the edge of the damper plate.
Attach by securing the bolt provided to the damper plate with
an adjustable wrench. (Fig. 3)
If the Damper Clamp does not fit, drill a ¼” hole onto the
damper plate and install an anchor bolt with a nut, at a 90 de-
gree angle, so that the damper plate will remain fully open.
The proper finished installation of the Damper Clamp is
shown in Figure 4. If the bolt fails to block the damper in
an open position, the damper should be removed from the
chimney.
To check your vent for proper drafting: Light a tightly rolled
newspaper on one end and place it at the inside front edge
of the fireplace. Observe the smoke and be sure the vent
is properly drawing it up the chimney. If the smoke is drawn
back into the room, extinguish the flame and remove any ob
-
struction until proper venting is achieved. If that fails, check
with a qualified chimney sweep.
