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.
Optional brass trim accessories are available
(see Accessories, page 17). The brass trim
will extend past sides of firebox approximately
1/2". 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 6. Follow the instructions below 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 in Table 1
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 In-
stalling Gas Line, page 11 and Connecting
to Gas Supply in log set owner’s manual.
IMPORTANT: If installing blower accessory
(circulating models with louvers only), see
Hard-Wiring Firebox, page 15.
3. Carefully set firebox in front of rough open-
ing with back of firebox inside wall open-
ing. IMPORTANT: If installing a perimeter
trim kit, see instructions included with
trim accessory. You must install shoulder
screws from trim kit now.
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 on page 11).
