Requirements
WARNING: Maintain all minimum clearances to combusti-
bles from the appliance and vent system.
Utilizing the Kozy Power Vent system will not change
mantel, hearth, sidewall, facing and finishing require-
ments from the standard design option.
Ensure finishing material does not inhibit the installation
and removal of the safety barrier (See Section 2.4).
Finishing material cannot obstruct ventilation air.

Combustible Mantel Projections: As referenced in
FIGURE 5.2 the 3/4" mantel trim can start at
9" (229mm) above the top finishing edge with a
6" (152mm) mantel starting at 12-1/2" (317mm)
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: Combustible flooring can run
underneath this appliance which would then allow an
unlimited combustible hearth projection. The hearth
projection cannot be elevated (vertically) past the
base of the fireplace / enclosure floor.
•
Mantel Leg: Follow "Side Combustible Clearance"
below. See FIGURE 5.4.
•
Combustible Sidewall Clearance: the adjacent
sidewall projection is unlimited and starts at
1" (25mm) from the side of the fireplace. See FIGURE
5.4.
5.1.2 Non-combustible Mantel or Surround
Requirements
•
Noncombustible Mantel Projections: As referenced in
FIGURE 5.3, the 8" noncombustible mantel projection
can start at 41-3/4" (1060mm) from the base of the
fireplace. This measurements places the noncombus-
tible mantel flush with the top piece of the finishing
trim kit (#NK48-FTK) when installed.
•
Noncombustible Surround (top and sides of fireplace
opening): As referenced in FIGURE 5.3, the 8" non-
combustible surround can be installed flush at the
side and top finishing edge of the finishing trim kit.
The drawing shows a 1" gap from the top and sides of
the fireplace which allows for the installation of the
finishing trim kit (#NK48-FTK).
•
Follow projection 1" (25mm) up for every 1" (25mm)
deeper.

5.1.4 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. 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 manufacturers
recommendations.
•
For a painted surface, use a high quality acrylic latex
primer and finish coat. Avoid flat or light-colored paints to
prevent discoloring.
Disclaimer: Kozy Heat does not guarantee any materials used
around the fireplace. Kozy Heat disclaims any and all liability
for any damage to finishing materials including warping,
discoloring, cracking, peeling or flaking. This also includes any
off-gassing or unpleasant smells from materials when they are
