Chimneys for
masonry replaces begin with an Anchor
Plate or Anchor Plate with Damper. 
Anchor Plate with Damper is not allowed in
chimneys serving stoker-red, liquid or gas-
burning appliances.  Do not install
Anchor Plate with Damper on Factory-built
replaces. Important: be sure the surface
of the masonry chimney has a surface
on which to attach the Anchor Plate or
Anchor Plate. If the top of the masonry does
not have a level surface, then you will need to
modify the masonry accordingly. Center the
Anchor Plate over the masonry ue opening.
If a Damper is used, make sure nothing
interferes with the damper plate movement.
Seal the Anchor Plate in place with a high-
temperature sealant. Secure Anchor Plate
with (4) 2” x 1/4” masonry anchors (Fig. 2).

swing freely once the Anchor Plate is installed.
When the chain is pulled down, the damper
plate should close (horizontal position). When
the chain is released (no weight on the chain),
the damper should swing open (vertical
position).

the closed (horizontal) position, determine
and mark the location for the Lintel Hook. The
Lintel Hook should be mounted in a position
so as to provide a small amount of tension in
the spring attached to the chain (Fig. 3). The
