NOTE
Installing two ½" cement board
under the unit is mandatory. If
a combustible framing is built, it
must be strong enough to support
the weight of the fireplace and
cement board must be installed
over it.

NOTE
Framing is not always perfectly level. We
suggest that at least /'' clearance be
added to the dimensions listed in the table.
