STEP 3: AT THE FIREPLACE
A. Mount bracket in fireplace
•
Using 1/4” masonry drill bit, drill one hole about 1” deep into firebrick towards
the front of the fireplace and about 20” off the firebox floor (see illustration).
Important: If brick is loose, first repair it with refractory
mortar or call local mason.
Caution: Wear safety glasses when drilling. Use only
masonry drill bit. Failure to do so can cause cracks in the
firebox wall.
•
Insert nail anchor in top hole of bracket and secure
to firebox wall with hammer.
•
Drill second hole after bracket is attached to
firebox wall. Add second nail anchor and secure.

B. Install cable handle
•
Pull cable through bracket until a slight tension
can be felt. Damper should now be closed.
•
Slide brass lug onto cable 1/2” above bracket (see
illustration).
•
Close damper by pulling cable down and placing
lug under bracket.

Bracket and Handle Assembly]
C. Check and adjust operation
•
Return to the roof and check that the damper is tightly sealed. If it is not, adjust lug
upward for better seal. Do not overdo it – if lug is raised too far, this may activate the
cable leg and actually open the damper.
•
Cut off excess cable.
