MANTLE CLEARANCES
**
EXAMPLE A - NON-COMBUSTIBLE MATERIAL
It is best to frame your fireplace after it is positioned and
the vent system is installed. Use 2x4's and frame to local
building codes. To install the fireplace face flush with the
finished wall, position the framework to accomodate the
thickness of the finished wall.
MAINTAIN THESE MINIMUM CLEARANCES TO COM-
BUSTIBLES:
Fireplace framing - 0" to stand-offs (top, rear & sides)
Fireplace finishing - 3" to sides, 7¼" to top of unit

EXAMPLE B - BEVELLED TRIM
The non-combustible finishing material may be eliminated
if the intent is to finish the unit with the optional 6" bevelled
trim.
