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 stove’s 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 stove’s flue exit through the damper area of the fireplace and into the chimney tile liner. See figure 9.
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.
The inside area of the flue liner must not be less than the area of the stove’s flue exit, and cannot be more than three times greater than the cross sectional area of the stove’s 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
When installing the F 3 CB to a prefabricated metal chimney always follow the pipe manufacture’s 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.
