Mantel Clearances for Built-In
Installation
If placing custom mantel above built-in rebox,
you must meet the minimum allowable clearance
between mantel shelf and top of rebox 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 heater to touch
or extend beyond the rebox
screen.
If your installation does not meet the above mini-
mum clearances in Figure 7, you must:
raise the mantel to an acceptable height,
OR
remove the mantel.

BUILT-IN FIREBOX INSTALLATION
Built-in installation of this rebox involves installing
rebox into a framed-in enclosure. This makes the
front of rebox ush with wall. Optional perimeter
brass trim accessories are available (see Accessories,
page 18). The brass trim will extend past sides of
rebox approximately 1/2". This will cover the rough
edges of the wall opening. If installing a mantel above
the rebox, you must follow the clearances shown
in Figure 7. Follow the instructions below to install
the rebox in this manner.
1. Frame in rough opening. The rebox framing
should be constructed of 2 x 4 lumber or heavier.
Construct framing using dimensions shown in
Figure 8 and 9, page 10. It is recommended that
the framing be constructed rst and the unit
be placed in position by removing the nailing
anges from one side. After sliding the unit into
place, the outer most anges may be replaced
and nailed to the framing on all sides before
applying the wallboard to the exterior framing.
