• Diagrams, illustrations, and photographs are

Instructions.

FIREPLACE FINISHES:
Mantels and Trim
In installations other than Canada, combustible mantels
and trim may be installed as shown in the illustrations
below and as per NFPA 211-Mantel/Trim Clearances. If a
mantel is of a noncombustible material, it is exempt from
these requirements as long as it does NOT interfere with
the installation or operation of glass doors.
For combustible mantel and trim specifications in
Canadian installations (EST-36 and EST-42 only), see
the fireplace Installation Instructions.
FIREPLACE FINISHES:
Vertical Surround Limitations
Combustible materials may project beyond the sides
of the fireplace opening as long as they are kept
within the shaded area illustrated below.
FIREPLACE FINISHES:
Hearth Extensions and Wall Shields
A hearth extension must be installed with all
fireplaces. Its purpose is twofold: 1) to protect a
combustible floor in front of the fireplace from
both radiant heat and sparks; and 2) to distinguish
the prescribed hearth extension area from other
unprotected surfaces.

Typical Installation
Note:
• The framed depth from a framed wall
(item “G” in the Framing Dimensions
table below) must always be measured
from a finished surface. If a wall
covering (such as drywall) is to be
attached to the rear wall, measure the
framed depth from the drywall surface.
This dimension MUST be exact.
• If the appliance is to be elevated
above floor level, a solid, continuous,
platform must be constructed.
• The header may rest on the top metal
spacers; however, NEVER notch the
header to fit around the spacers.
• Consult all local codes.
