Finishing

A. Facing and Finishing Instructions
WARNING! Risk of Fire! Comply with all minimum clear-
ances to combustibles as specified. Framing closer than the
minimums listed must be constructed entirely of noncom-
bustible materials (i.e., steel studs, concrete board, etc.).
Splatter Guard
The splatter guard is a piece of corrugated material
used to protect the appliance during the installation
process before finishing work on the whole hearth is
complete. A splatter guard is factory-installed on
MEZZO-AU models. Splatter guards must be removed
before appliance is fired.
WARNING! Risk of Fire! Remove the splatter guard be-
fore lighting the appliance. Shut off gas to the appliance
when the splatter guard is in place to prevent accidental
operation.
Finishing Instructions
It is important to follow the framing and finishing instruc
tions to ensure proper placement of fireplace into the
surrounding framing / finishing materials.
Wall sheathing materials 1/2 in. (13 mm) thick are
specified in this installation manual to properly align
with the factory-installed non-combustible material.
WARNING! Risk of Fire! DO NOT remove the factory-
installed non-combustible board or cover it with combus-
tible material, such as:

Drywall (gypsum board)

Plywood

Materials that do not meet the ASTM E 136 Non-
combustibility standard (below).
Removal of factory-installed, non-combustible board
and/ or use of materials not meeting the ASTM E 136
standard could cause fire.
Non-Combustible Materials Specification
Material which will not ignite and burn. Such materials are
those consisting entirely of steel, iron, brick, tile, concrete,
slate, glass or plasters, or any combination thereof.
Materials that are reported as passing
Standard Test Method for Behavior of Materials in a
Vertical Tube Furnace at 750 ºC.
WARNING! Risk of Fire! Maintain specified air space
clearances to combustibles. Inadequate air space could
cause overheating and fire.

Finishing Materials
NOTICE: The maximum finishing material not only
includes the decorative finish materials (marble, tile,
slate, etc) but also the thin set, lath and adhesive
used to attach the decorative finish material.
WARNING! Risk of Fire! DO NOT use screws longer
than two inches when attaching finishing materials to
factory-installed non-combustible material. Screws lon-
ger than two inches will compromise clearance and
could cause overheating and fire.
WARNING! Risk of Fire, Explosion or Asphyxiation!
DO NOT use screws more than one inch long on lower
cover panel. Longer screws may penetrate gas line or
damage valve or electrical components.
This section discusses installation details associated
-
with the Inside and Overlap Fit methods and specifies
additional non-combustible materials required.
When finishing the wall around the fireplace, it is critical
that wall sheathing be fastened properly. Wall sheathing
fasteners, such as screws or nails, are not permitted in
some locations. See Figure 10.1.
It is acceptable to pre-drill holes and use self-tapped
screws in the factory-installed non-combustible board
which may be used to lathe (a backer for tile, marble,
etc.). Screws being installed through the factory-installed
non-combustible board should be self-tapping type with
a maximum length of 2 in. (51 mm) See Figure 10.1.
When installing finish material on the lower cover panel,
DO NOT drill or install screws longer than one inch.
Screws longer than one inch could penetrate the lower
cover panel causing damage to components or penetrate
the gas line. One inch screws are included in the manual
bag assembly that are intended for use when attaching
finishing material to lower cover panel. See Figure 10.1.
