4.0 FACING AND FINISHING
4.1 Facing and Finishing Requirements
WARNING: Maintain all minimum clearances to combustibles from the
appliance and vent system.
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 , the 3/4" trim mantel can start at 10" (254mm) above the
top of the appliance with a 10" (254mm) mantel starting at 14"
(354mm) above the top of the appliance. Mantel projections
can increase 1" (25mm) of depth for every 1" (25mm) of height
starting at the 10" (254mm) mantel.
• Non-combustible Mantel Projections - Minimum Vertical
and Maximum Horizontal: A minimum vertical clearance of
6" (152mm) above the top of the appliance 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 24.
4.1.2 Adjacent Sidewall Requirements
• The adjacent sidewall minimum clearance is 1-1/4" (32mm) from
the appliance sides. See FIGURE 4.3 on page 25.
4.1.3 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. Co., Inc. recommends
the following methods:
• The front face of the unit to the insulation piece and stand-
off assembly will accommodate typical 1/2" (12mm) non-
combustible facing material. The non-combustible facing
material will sit on top of the unit and be pushed back tight
against the insulation piece in-between the stand-off assembly
pieces, allowing the unit front to be flush with non-combustible
facing material. These components are adjustable for the non-
combustible facing material to be flush with the fireplace or
to overlap the fireplace face. Refer to section 3.3, STAND-OFF
ASSEMBLY AND HEADER HEAT SHIELDS on page 12.
• This appliance is shipped with a 1/2" thick non-combustible
material (board) that overlaps the header and the sides of
framing. See section FIGURE 4.4, NON-COMBUSTIBLE
MATERIAL on page 26. Screws are allowed to penetrate the
steel framing assembly to attach finishing material.
• An optional finishing trim kit #C39-FTK provides a finished
edge to hide unfinished edge materials. See Section section
4.2, OPTIONAL FINISHING TRIM KIT (FTK): #C39-FTK
on page 27.
• 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.
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.
