appliance and vent system.
NOTE: See Section 4.5 Vented Cavity and KZK Facing and Finishing
Requirements on page 43 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 4.4 Finishing Guidelines for
Optional Surrounds on page 42 for allowable space
for finishing materials to ensure a proper fitting of the
surround. Use measurement in 'B' in Figure 4.10 on page
42 for the required space necessary from the bottom of
the fireplace finishing edge to the hearth.
•
Combustible Mantel Projections:
As referenced in Figure 4.1
(page 35), the 3/4" (19mm) trim can start at 8" (203mm) above
the top finishing edge with a 6" (152mm) mantel starting at 11-
1/2" (292mm) 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 (page 35),
the bottom of the bottom finishing edge can be flush with the
top of the hearth if not using any optional surround.
If installing
an optional surround
,
refer to Measurement 'B' in Section 4.4
Finishing Guidelines for Optional Surrounds on page 42.
•
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

'A', in Section 4.4 Finishing Guidelines for Optional Surrounds on
page 42, for the space required from the optional surround
sides to finishing material.
4.1.2 Adjacent Sidewall Requirements
•
The adjacent sidewall minimum clearance is 0" (0mm) from the
side finishing edges of the fireplace. See Figure 4.3 on page 37.
If installing an optional surround
,
refer to Measurement 'A', in
Section 4.4 Finishing Guidelines for Optional Surrounds on page
42, 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 1/2" (13mm) thick. See Figure
4.5 on page 39 for dimensions.
•
An optional finishing trim kit #CWST-FTK provides a 3/4" (19mm)
finished edge to hide unfinished edge materials. See Section 4.2
Optional Finishing Trim Kit (FTK): CWST-FTK on page 40.
•
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. Refer to Figure 4.6 on page 39.
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.
