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 41). 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, page 10. Follow these instructions
to install the firebox in this manner.
1. Frame in rough opening. Firebox framing
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 fin
-
ished 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
Connecting to Gas Supply,
page 13).
