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, page 11. Follow these instructions to install
the firebox in this manner.
1. Frame in rough opening. The firebox fram-

ing should be constructed of 2 x 4 lumber
or heavier. Use dimensions and rough
opening layout in Figure 8. Adjust framing
so that firebox flushes with finished wall
surface. If installing in a corner, use dimen-
sions in Figure 9, for rough opening.

2. Install gas piping to firebox location. See

Installing Gas Line on page 14 and Con-
necting 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).

6. Install and properly test gas log heater.

Follow installation instructions 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 fac-
ing, but should never cover any necessary
openings.

WARNING: Do not allow non-

combustible materials to cover

any necessary openings.
