4.0 FACING AND FINISHING
4.1 Facing and Finishing Requirements
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 8" (203mm) mantel can start 12" (305mm) above the top
finishing edge. Mantel projections can increase 1" (25mm) of
depth for every 1" (25mm) of height starting at the 8" (203mm)
mantel.
•
Mantel Leg:
There is a required 12" (305mm) clearance to any
combustible or non-combustible mantel leg.
•
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 22.
4.1.2 Adjacent Sidewall Requirements
•
The adjacent sidewall minimum clearance is 12" (305mm) from
the side finishing edges of the fireplace.
4.1.3 Facing Requirements
NOTE: Non-combustible material such as brick, tile, marble, or stone
may be placed over the top and side face sections. This material MUST
NOT come in direct contact with fireplace, or cracking of face material
will occur.
CAUTION: If using ‘thin’ brick as facing, non-combustible facing
material, such as rock board or metal, must be used underneath the
‘thin’ brick. Do not attach any material directly to fireplace face.
•
Facing material should overlap side framing member
approximately 1/4” to 3/8” (6mm to 10mm).
•
Framing materials should not come in actual contact with the
fireplace.
•
Non-combustible material is required at the top and sides of the
fireplace. See Figure 4.3, Non-combustible Finishing Dimensions
on page 23.
•
Install facing material up to the finishing edge. Do not apply any
material beyond this point.
•
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 is dry and
dust free.
•
For taping and applying joint compound, we recommend heat
resilient tape, mesh, and joint compounds, such as Durabond.
The 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.
