simplify and reduce installation cost. The fireplace
may be installed
directly
on the floor
or
elevated
on
a
wooden or masonry l,Iatform if desired. However. the
floor or platform must be solid and continuous to
prevent any air from entering the room from under
the fireplace. See Page 5 for chase construction.
The fireplace may be positioned and then the fram-
ing built around
it
or
the framing may be constructed
and the fireplace pushed into the opening. (See
Fig. 10.) The dimensions shown on Pages 2 and 3
may
be used
to
construci
the fireplace opening.
CORNER INSTALLATION
This can be the most economical in
rooms
where
wall space is at a premium. Because of the slanted
sides, the fireplace seems to take less area of floor
space than being
proiected
into the
room
from a flat
wall. (See Fig.
5.)
