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 perimeter trim is available (see
Ac-
cessories
, page 14) This perimeter trim will
extend past sides of firebox approximately
1/". This will cover rough edges of the wall
opening. If installing a mantel above the fire-
box, you must follow the clearances shown in
Figure 7, page 8. Follow the instructions below
to install the firebox in this manner.
