Facing and Finishing Requirements
WARNING: Maintain all minimum clearances to combustibles from the
appliance and vent system.
WARNING! RISK OF FIRE : The following facing and finishing options are
for use ONLY when using an optional vented cavity or Komfort Zone Kit
with the convection baffle and cover plates removed. DO NOT follow
these options unless you are using the vented cavity option.
4.3.1 Mantel and Hearth Requirements
WARNING: All minimum clearances to combustible material MUST be
maintained.
•
Combustible Hearth and Mantel Projections

•
Mantel Leg:
Follow side combustible clearance below.
See
FIGURE 4.9

•
Side Combustible Clearance:
1” (25mm) combustible side trim
projection can be flush with the side finishing edge. After 6”
(152mm), this projection is unlimited. See
FIGURE 4.9

4.3.2 Adjacent Sidewall Requirements
•
The adjacent sidewall minimum clearance is 6" (152mm) from
the side finishing edge of the fireplace.
See
FIGURE 4.9

4.3.3 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 37.
•
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 attach 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).
4.3.4 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.
4.3.4.1 Combustible Wall Finish
•
FIGURE 4.10
on page 42 shows installation of combustible
wall finish up to 1" (25mm) thick for Vented Cavity and
Komfort Zone Kit(s) installations. For KZK-1510A and KZK-038
installations, reference the manuals included with the kit.
•
Finishing materials cannot block the required vented cavity
discharge opening requirements.
•
This combustible material goes on any required non-
combustible materials as shown in
FIGURE 4.5
on page 37.
•
This 1" (25mm) combustible material is able to go down to the
fireplace finishing edge and up to the air discharge opening.
