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 5. Follow these instructions to install the
firebox in this manner.
1. Frame in rough opening. The firebox framing should be con-
structed of 2 x 4 lumber or heavier. Use dimensions and rough
opening layout in Figure 6a. Adjust framing so that firebox
flushes with finished wall surface. If installing in a corner, use
dimensions in Figures 6b for rough opening.
2. Install gas piping to firebox location. See Installing Gas Line on
page 11 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 7, page 10).
6. Install and properly test gas log heater. Follow installation in-
structions included with the vent-free gas log heater that is
being installed.

Mantel Clearances for Built-In Installation
If placing custom mantel above built-in firebox, you must meet the
minimum allowable clearance between mantel shelf and top of
firebox opening shown in Figure 5. These are the minimum allow-
able mantel clearances for a safe installation. Use larger clearances
wherever possible to minimize the heating of objects and materials
placed on the mantel.
CAUTION: Do not allow the vent-free gas log
heater to touch or extend beyond the fireplace screen.
