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 the firebox, you must follow the clearances
shown in Figure 7. Follow these instructions 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 and rough opening lay-
out in Figure 8. Adjust framing so that firebox flushes with finished
wall surface. If installing in a corner, use dimensions in Figure 9,
for rough opening.
2. Install gas piping to firebox location. See
Gas Line Installation
on
page 14 and
Connecting to Gas Supply
in log set owner’s manual.
3. Carefully set firebox in front of rough opening with back of firebox
inside wall opening.
4. Carefully insert firebox into rough opening.
5. Attach firebox to wall studs using nails or wood screws through
holes in nailing flange (see Figure 10, page 11).
6. Install and properly test gas log heater. Follow installation in-
structions included with the vent-free gas log heater that is being
installed.
IMPORTANT:
When finishing your firebox, combustible materials such
as wall board, gypsum board, sheet rock, drywall, plywood, etc. may
be butted up next to the sides and top of the firebox. Combustible
materials should never overlap the firebox front facing.
WARNING: Do not allow any combustible materials
to overlap the firebox front facing.
IMPORTANT:
Noncombustible materials such as brick, tile, etc.
may overlap the front facing, but should never cover any necessary
openings.
WARNING: Do not allow noncombustible materials
to cover any necessary openings.
WARNING: Do not fill the spaces around the firebox
with insulation or other materials.
WARNING: Framing may be placed or rest against
fireplace spacer, however; framing must never be
notched.
WARNING: Do not alter, cut or modify fireplace
spacers.
