Mantel Clearances for Built-In
Installation
If placing custom mantel above built-in fire-
box, you must meet the minimum allowable
clearance between mantel shelf and top of
firebox opening shown in Figure 7. These are
the minimum allowable 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 appliance to
touch or extend beyond the
firebox screen.
If your installation does not meet the above
minimum clearances in Figure 7, you must:
• raise the mantel to an acceptable height,
OR
• remove the mantel.
Wall board or facing material (above firebox)
may be of combustible material, including
decorative mantel ornaments or other similar
projections off of the facing material.

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 perimeter brass trim acces-
sories 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 7. 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. Construct framing
using dimensions shown in Figure 8 and
9, page 11. It is recommended that the
framing be constructed first and the unit
be placed in position by removing the
nailing flanges from one side. After sliding
the unit into place, the outer most flanges
may be replaced and nailed to the framing
on all sides before applying the wallboard
to the exterior framing.
2. If the vent-free firebox is to be installed
directly on carpeting, tile (other than ce-
ramic) or any combustible material other
than wood flooring; the vent-free firebox
must be installed upon a metal or wood
panel extending the full width and depth
of the vent-free firebox.
3. If a raised platform is to be constructed,
ceiling clearances must be maintained.
4. Install gas piping to firebox location. See
Installing Gas Line and Connecting to Gas
Supply in log set owner's manual.
IMPORTANT: If installing blower accessory.
See Hard-Wiring Firebox, page 13.
5. Carefully set firebox in front of rough open-
ing. IMPORTANT: If installing brass trim
kit, see instructions included with brass
trim accessory. You must install shoulder
screws from brass trim kit now.
6. Carefully insert firebox into rough opening.
7. Attach firebox to wall studs using nails
or wood screws through holes in nailing
Note: Gas line
may also be on
opposite side.
