BUILT-IN FIREBOX INSTALLATION
Built-in installation of this firebox involves in-
stalling firebox into a framed-in enclosure. This
makes the front of firebox flush with wall. Optional
perimeter trim is available (see
Accessories, page
12) This perimeter trim will extend past sides of
firebox approximately 1/2 inch. This will cover
rough edges of the wall opening. If installing a
mantel above the firebox, you must follow the
clearances shown in Figure 7, page 8. Follow
the instructions below to install the firebox in
this manner.
1. Frame in rough opening. Use dimensions shown
in Figure 17 for the rough opening. If installing
in a corner, use dimensions shown in Figure 18
for the rough opening. The height is 33", which
is the same as the wall opening in Figure 17.
2.
Install gas piping to firebox location. This instal-
lation includes an approved flexible gas line (if al
-
lowed by local codes) after the equipment shutoff
valve. The flexible gas line must be the last item
installed on the gas piping. See Connecting to
Gas Supply in log set ownerʼs manual.
