BUILT-IN FIREBOX INSTALLATION
Built-in installation of this fi rebox involves
installing fi rebox into a framed-in enclosure.
This makes the front of fi rebox fl ush with wall.
Optional brass trim accessories are available
(see Accessories, Page 16)
. Brass trim will
extend past sides of fi rebox approximately
1/2". This will cover rough edges of wall open-
ing. If installing a mantel above fi rebox, you
must follow clearances shown in
Figure 6
.
Follow these instructions to install fi rebox 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 7a
. Adjust
framing so that fi rebox is fl ush with fi n-
ished wall surface. If installing in a corner,
use dimensions in
Figures 7b, 7c and 7d
for rough opening.
