Mantel Clearances for Built-In Installation
If placing custom mantel above built-in fi rebox, you must meet
the minimum allowable clearance between mantel shelf and top of
fi rebox opening shown in
Figure 7
. 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 fi replace screen.
NOTICE: Surface temperatures of adjacent walls and
mantels become hot during operation. Walls and
mantels above the fi rebox may become hot to the
touch. If installed properly, these temperatures meet
the requirement of the national product standard. Fol-
low all minimum clearances shown in this manual.
NOTICE: If your installation does not meet the minimum
clearances shown, you must do one of the following:
• raise the mantel to an acceptable height
• remove the mantel
BUILT-IN FIREBOX INSTALLATION
Built-in installation of this fi rebox involves installing fi rebox into a
framed-in enclosure. This makes the front of fi rebox fl ush with wall. If
installing a mantel above the fi rebox, you must follow the clearances
shown in
Figure 7
. Follow these instructions to install the fi rebox in
this manner.
1. Frame in rough opening. The fi rebox framing should be constructed
of 2 x 4 lumber or heavier. Use dimensions and rough opening layout
in
Figure 8
. Adjust framing so that fi rebox fl ushes with fi nished
wall surface. If installing in a corner, use dimensions in
Figure 9
,
for rough opening.
2. Install gas piping to fi rebox location. See Gas Line Installation on
Page 13
and Connecting to Gas Supply in log set owner’s manual.
