FIREPLACE INSTALLATION
SECURE FIREPLACE TO FRAMING
The fireplace must be secured to the framing studs as
shown in
Figure 6.
Use eight (8) screws to attach fireplace
to framing. The side nailing flanges are
1
⁄
2
" or
5
⁄
8
" to accom-
modate different wall thickness.
NOTE
Never install combustible materials over
front face of fireplace.
FINISHING MATERIAL
NOTE:
Any remote wiring (i.e. remote control, wall
switch), must be done prior to final finishing to avoid costly
reconstruction.
Only noncombustible materials (i.e. brick, tile, slate, steel,
or other materials with a UL fire rating of Zero) may be
used to cover the black painted face of the appliance. It is
permissible to bring combustible wall board to the top of
the standoffs on the top and to the wall board stand-offs
on the sides of the unit. A 300°F minimum adhesive may
be used to attach facing materials to the black surface. If
joints between the finished wall and the fireplace surround
are sealed, a 300°F minimum sealant material (General
Electric RTV103 or equivalent) must be used.
NOTE:
Fireplace may be installed on top of framing or
platform constructed of combustible materials which do
not protrude beyond the face.
NONCOMBUSTIBLE FACING INSTALLATION
CAUTION
: The noncombustible wall board supplied with
this unit can be damaged if dropped or struck. Handle
with care.
1. Using drywall screws secure noncombustible board to
the two brackets on top of unit.
IMPORTANT
: To avoid
cracking the board, pre-drill holes prior to securing to the
unit/framing.
2. Wipe any debris or dust from the noncombustible board
and drywall.
3. It is highly recommended to prime the facing using a
quality primer prior to taping and mudding. This will
ensure proper adhesion of both the tape and mud. The
supplied board is very porous.
4. Tape the seams using a mesh type tape.
5. Mud seams as normal. We recommend using a product
called Durabond high strength compound for the first
coat. This product can be purchased at any hardware
store. Follow manufacturer's recommendations for curing
the mud. NOTE: Depending upon the final finishing
method, use a minimum rated 300 degree sealant, dry
-
wall compound or thin set to seal the side and top joints.
6. Prime wall for a second time for proper adhesion of paint.
