5.2 Facing and Finishing Requirements
5.2.1 Mantel Requirements
WARNING: Maintain all minimum clearances to combustibles from the
appliance and vent system.
•
Combustible Mantel Projections - Minimum Vertical and
Maximum Horizontal: 14-1/4 in (362 mm) is the minimum
vertical clearance from the top of the finishing edge to 9 in (229
mm) maximum depth of a combustible mantel. Combustible
mantels at the minimum vertical clearance may be 0 in (0 mm) to
9 in (229mm) depth with minimum vertical clearance 14-1/4" in
(362 mm).
•
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
5.2.2 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 ½ in (13mm) 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.

•
Do not secure material to the lower cover panel using screws.
This may damage control system components. To secure material
to this area, use 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. Do not use excessively long screws.
5.2.3 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.
