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 4.4 Vented Cavity Facing and Finishing Options on
page 30 additional mantel, hearth, and sidewall clearances.
NOTE: If installing a Kozy Komfort Zone Kit (#KZK-072), see manual
included with the kit for additional mantel, hearth, and sidewall
clearances.
4.1.1 Mantel Requirements
WARNING: All minimum clearances to combustible material MUST be
maintained.
•
Combustible Mantel Projections - As referenced in Figure 4.1,
the 3/4" trim can start at 16-1/2" (419mm) above the finishing
edge with a 6" (152mm) mantel starting at 20" (508mm) above
the finishing edge. Mantel projections can increase 1" (25mm) of
depth for every 1" (25mm) of height starting at the 6" (152mm)
mantel.
•
Non-combustible Mantel Projections - Minimum Vertical and
Maximum Horizontal: A minimum vertical clearance of 6 in (152
mm) above the finishing edge to a maximum 6 in (152 mm)
depth of a non-combustible mantel. Follow projection 1 in (25
mm) up for every 1 in (25 mm) deeper. See Figure 4.2.
4.1.2 Adjacent Sidewall Requirements
•
The adjacent sidewall must be 6" (152mm) from the finishing
edge of the fireplace.
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 in (19mm) thick.
•
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.
•
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. 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.
