shown, you must do one of the
following:

BUILT-IN FIREBOX INSTALLATION
Built-in installation of this firebox involves install-
ing firebox into a framed-in enclosure. This makes
the front of firebox flush with wall. Optional brass
trim accessories are available (see Accessories,
page 14). The brass trim will extend past sides
of firebox approximately 1/2". This will cover
the rough edges of the wall opening. If installing
a mantel above the firebox, you must follow the
clearances shown in Figure 6. Follow the instruc-
tions below to install the firebox in this manner.
Wall board or facing
material (above
firebox) may be of
combustible material,
including decorative
mantel ornaments or
other similar projec-
tions off of the facing
material.

1. Frame in rough opening. The firebox fram-
ing should be constructed of 2 x 4 lumber or

that firebox flushes with finished wall surface.
If installing in a corner, use dimensions in
Figures 7b, 7c and 7d for rough opening.

ing with back of firebox inside wall opening.
