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 4.10 Vented Cavity and KZK Facing and Finishing
Requirements on page 44 additional mantel, hearth, and sidewall
clearances.
4.1.1 Mantel and Hearth Requirements
WARNING: All minimum clearances to combustible material MUST be
maintained.
•
Combustible Mantel Projections:
the 3/4" trim can start at 16" (407mm) above the top finishing
edge with a 6" (152mm) mantel starting at 19-1/2" (496mm)
above the top finishing edge. Mantel projections can increase 1"
(25mm) of depth for every 1" (25mm) of height starting at the 6"
(152mm) mantel.
•
Combustible Hearth: As referenced in Figure 4.1, the bottom
of the bottom finishing edge can be flush with the top of the
hearth.
•
Non-combustible Mantel Projections: A minimum vertical
clearance of 6" (152mm) above the top 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 on page 31.
•
Mantel Leg: Follow side combustible clearance below.
Figure 4.3 on page 32.
•
Side Combustible Clearance: 1" (25mm) combustible side
trim starts at 3" (76mm) from the side finishing edge. After 6"
(152mm), this projection is unlimited. See Figure 4.3 on page
32
4.1.2 Adjacent Sidewall Requirements
•
The adjacent sidewall minimum clearance is 6" (152mm) from
the side finishing edges of the fireplace. See Figure 4.3 on page
32.
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 1/2" (13mm) thick. See Figure
4.5 on page 34 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.
•
It is acceptable to pre-drill holes and to use self-tapping screws
prior to attaching the non-combustible material to the top
and sides of the fireplace face. 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 are dry and
dust free.
•
For taping and mudding seams, we recommend heat
resilient tape, mesh and joint compounds, such as Durabond.
Joint compound 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.
