4.0 FACING AND FINISHING
4.1 Standard Installation Facing
and Finishing Requirements
4.1.1 Mantel Requirements
WARNING: All minimum clearances to combustible material MUST be
maintained.
Mantel drawings are shown without the horizontal heat shield for
clarification only.
Combustible Mantel Projections:
As referenced in Figure 4.1 (page
the
3/4” (19mm) trim can start at 5-1/2” (139mm) above the top
of the appliance with a 6” (152mm) mantel starting at 9” (229mm)
above the top of the appliance. Ma
ntel projections can increase 1”
(25mm) of depth for every 1” (25mm) of height starting at the 6”
(152mm) mantel.
Combustible Mantel Projections FOR B41-RSF2 ONLY:
As referenced
in Figure 4.2 (page 19), the 3/4” (19mm) trim can start at 1-1/2”
(38mm) above the top of the appliance with a 6” (152mm) mantel
starting at 5” (127mm) above the top of the appliance. Ma
ntel
projections can increase 1” (25mm) of depth for every 1” (25mm) of
height starting at the 6” (152mm) mantel.
Non-combustible Mantel Projections:
A minimum vertical clearance
of 6 in (152 mm) above the appliance 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.
4.1.2 Adjacent Sidewall Requirements
•
The adjacent sidewall must be 1” (25mm) from the finishing edge
of the fireplace. See Figure 4.3 (page 20).
•
If you are installing safety barrier B41-PTF2, you will need a 3”
(76mm) clearance from the outside edge to the adjacent sidewall
for proper fitting of the safety barrier.
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. 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.
4.1.4 Non-Combustible Zone
•
A 42-7/8” x 10-1/2” non-combustible material (board) is supplied
with this fireplace. The non-combustible material (board) allows
3/4” overlap onto framing side and 1/2” overlap onto header. See
Figure 4.4, BAY-41 Non-Combustible Zone on page 20.
