4.0 FACING AND FINISHING
4.1 Standard Installation Facing
and Finishing Requirements
WARNING: Maintain all minimum clearances to combustibles from the
appliance and vent system.
NOTE: See Section 4.5 Vented Cavity and KZK Facing and Finishing
Requirements on page 38 additional mantel, hearth, and sidewall
clearances.
4.1.1 Mantel and Hearth Requirements
WARNING: All minimum clearances to combustible material MUST be
maintained.
IMPORTANT: If you plan to install a hearth and an optional
surround, reference Section 4.3 Finishing Guidelines for
Optional Surrounds on page 36 for allowable space
for finishing materials to ensure a proper fitting of the
surround. Use measurement in 'B'
36 for the required space necessary from the bottom of
the fireplace finishing edge to the hearth.
•
Combustible Mantel Projections (no surround): As referenced
in Figure 4.1, the 3/4" trim can start at 20-3/8" (518mm) above
the finishing edge with a 6" (152mm) mantel starting at 23-7/8"
(607mm) above the finishing edge when installing with no
surround. Mantel projections can increase 1" (25mm) of depth
for every 1" (25mm) of height starting at the 6" (152mm) mantel.
Refer to Section 4.3 Finishing Guidelines for Optional Surrounds
on page 36 if installing with an optional surround.
•
Combustible Hearth: As referenced in Figure 4.1, the bottom
of the finishing edge can be flush with the top of the hearth if
not using any optional surround. Refer to Section 4.3 Finishing
Guidelines for Optional Surrounds on page 36 if installing with
an optional surround.
•
Non-combustible Mantel Projections: A minimum vertical
clearance of 6" (152mm) above the finishing edge to a maximum
6" (152mm) depth of a non-combustible mantel. Follow
projection 1" (25mm) up for every 1" (25mm) deeper. See Figure
4.2.
4.1.2 Adjacent Sidewall Requirements
•
The adjacent sidewall minimum clearance is 0" (0mm)
finishing edge of the fireplace if installing without a surround.
If installing an optional surround,
Section 4.3 Finishing Guidelines for Optional Surrounds on page
36, for the space required from the optional surround sides to
finishing material.
4.1.3 Facing Requirements
•
Non-combustible material is required at the top and sides of
the fireplace. This fireplace is designed to accommodate non-
combustible facing material up to 3/4" (19mm) thick. See Figure
4.4 and Figure 4.5 for dimensions.
•
Install facing material up to the finishing edge that surrounds
the glass frame assembly. Do not apply any material beyond this
point. The glass frame assembly must be removable. If installing
an optional surround, refer to the measurements in Section 4.3
on page 36 as you may need to leave space from the finishing
edge for proper fitting of the surround.

•
Material may be attached to the bottom front cover panel using
a silicone sealant that has a 300°F (149°C) continuous exposure
rating.
•
It is acceptable to pre-drill holes and to use self-tapping screws
prior to attach the non-combustible material to the top and sides
of the fireplace face. In Figure 4.5, screws can only penetrate the
fireplace outer shell up to 1/2" (13mm) in the allowed areas.
4.1.4 Finishing Recommendations
NOTE: The surface area above the appliance may be affected by high
temperatures emitted from this appliance. To help avoid or reduce the
possibility of the sheetrock to crack, Hussong Mfg. Co., Inc. recommends
the following methods:
•
Ensure the non-combustible material and sheetrock is dry and
dust free.
•
For taping and mudding seams, we recommend heat resilient
tape, mesh and joint compounds, such as Durabond. Mud must
be cured as per manufacturer's recommendations.
•
For a painted surface, use a high quality acrylic latex primer
and finish coat. Avoid flat or light-colored paints to prevent
discoloring.
