FIREPLACE
Built-in installation of this firebox involves installing firebox
into a framed-in enclosure. Optional brass trim accessories are
available. The brass trim will extend past sides of firebox.
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 8, above. Follow the instructions
below to install the firebox in this manner.
1. Frame in rough opening. The firebox framing should be
constructed of 2 x 4 lumber or heavier. Use dimensions in
Table 2 and rough opening layout in Figure 1, 2 and 3,
pages 9, 10 and 11. Adjust framing so that firebox is flush
with finished wall surface.

IMPORTANT:
When finishing your firebox, combustible
materials such as wall board, gypsum board, sheet rock,
drywall, plywood, etc. may be butted up to the sides and top of
the firebox. Combustible materials should never overlap the
firebox front facing.
IMPORTANT:
Non-combustible materials such as brick, tile,
etc. may overlap the front facing, but should never cover any
necessary openings like louvered slots.
CAUTION
Log heaters installed in this firebox create warm air
currents. These currents move heat to wall surfaces next
to firebox. Installing firebox next to vinyl or cloth wall
coverings or operating firebox where impurities in the
air (such as tobacco smoke) exist, may discolor walls.
WARNING
Do not allow any materials to overlap the firebox front
facing.
WARNING
Never modify or cover the louvered slots on the front
of the firebox.
WARNING
Use only non-combustible mortar or adhesives when
overlapping the front facing with non-combustible
facing material.
WARNING
Do not allow non-combustible materials to cover any
necessary openings like louvered slots.
CAUTION
Do not install the firebox on carpet or vinyl.
