Facing and Finishing Requirements
WARNING: Maintain all minimum clearances to combustibles from the
appliance and vent system.
NOTE: See section
4.3,
(page 39) for additional mantel, hearth,
and sidewall clearances for vented cavity and Komfort Zone Kit
installations.
4.1.1 Mantel and Hearth Requirements
WARNING: All minimum clearances to combustible material MUST be
maintained.
•
Combustible Mantel Projections
: As referenced in
FIGURE 4.1
(page 33), the 3/4" mantel trim can start at 12" (305mm) above
the top finishing edge with a 6" (152mm) mantel starting at 15-
1/2" (394mm) 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 33),
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 34.
•
Mantel Leg
: Follow "Side Combustible Clearance" below.
See
FIGURE 4.3
on page 35.
•
Side Combustible Clearance
: 1” (25mm) combustible side trim
projection starts at 3” (76mm) from the side finishing edge.
After the first 6” (152mm) from the side finishing edge, the
combustible side trim projection is unlimited (unrestricted).
See
FIGURE 4.3
on page 35.
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 35.
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 37 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.
