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. If installing a mantel above firebox, you
must follow clearances shown in
Figure 4
.
Follow these instructions to install 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 and
rough opening layout in
Figure 6a
.
Adjust framing so that firebox is flush
with finished wall surface. If installing
in a corner, use dimensions in
Figures
6b, 6c and 6d
for rough opening.
2. Install gas piping to firebox location. See
Installing Gas Line,

necting to Gas Supply in log set owner’s

3. Carefully set firebox in front of rough
opening with back of firebox inside wall
opening.

or wood screws through holes in nailing
