buIlt-IN FIRebox INstAllAtIoN
Built-in installation of this firebox involves
installing firebox into a framed-in enclosure.
This makes the front of firebox flush with wall.
Optional brass trim accessories are available
(see Accessories, page 18). 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 instructions below to
install the firebox in this manner.
1. Frame in rough opening. The firebox fram-
ing should be constructed of 2 x 4 lumber
or heavier. Use dimensions in Table 1
and rough opening layout in Figure 7a.
Adjust framing so that firebox flushes
with finished wall surface. If installing in
a corner, use dimensions in Figures 7b,
7c and 7d for rough opening.
2. Install gas piping to firebox location. See In-
stalling Gas Line, page 12 and Connecting
to Gas Supply in log set owner's manual.
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.
