Breckwell P24FS - Manual (Page 13)

D. AS A BUILT-IN FIREPLACE
Figures 16 and 17 describe a P24 installation
vented into either a special chase built outside
an outer wall or a false inside wall. This is
especially suited for new construction or
remodeling.
The equipment compartment (sides and rear of
the stove in fireplace) must be enclosed per the
applicable electrical standards.
NOTE: Floor protection for Built-in raised
hearths requires a continuous sheet beneath to
prevent the possibility of embers falling through
to the combustible floor if cracks or separation
should occur in the finished surface.
The chase dimensions shown are
minimums and must be maintained.
