Hearth-mount into a Masonry Fireplace
The F 3 CB may be installed into a masonry fireplace
provided the opening is a minimum of 28 1/2 high.
The short leg package reduces the stoves height by
2 1/4.
When installing the F 3 CB into a masonry fireplace,
code requires that the fireplace damper plate be
removed or securely fixed in the open position. A
connector pipe must then extend from the stoves flue
exit through the damper area of the fireplace and into
the chimney tile liner. See figure 9.
The inside area of the flue liner must not be less than
the area of the stoves flue exit, and cannot be more
than three times greater than the cross sectional area
of the stoves flue exit.
If the chimney liner is too large to accommodate the
stove, an approved relining system must be installed
to resize the flue.
A new sheet metal damper block-off plate
must be
installed around the connector pipe at the damper
frame and sealed with the proper sealant (usually
High-Temp Silicone).
Fireplace installation must also observe the proper
clearances to surrounding trim and mantels (addressed
in clearance section of this manual). In addition,
fireplace installations must also adhere to the floor
protection guidelines specified in the following section.
Prefabricated Chimneys
When installing the F 3 CB to a prefabricated metal
chimney always follow the pipe manufactures in-
structions and be sure to use the components that are
required. This usually includes some type of smoke
pipe adapter that is secured to the bottom section of
the metal chimney and allows the chimney pipe to be
secured to it with three sheet metal screws.
See figures 10 and 11.
