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 aected 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-
o 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-o assembly
pieces, allowing the unit front to be ush with non-combustible
facing material. These components are adjustable for the non-
combustible facing material to be ush with the replace or
to overlap the replace 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 nishing material.
• An optional nishing trim kit #C39-FTK provides a nished
edge to hide unnished 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 nish coat. Avoid at or light-colored paints to prevent
discoloring.

7.3 Vent Restriction
Burner ame appearance and characteristics are aected by altitude,
fuel quality, venting conguration, and other factors. To achieve
desirable ame appearance, the vent exhaust may be restricted by
the restrictor plate (included in components packet) and/or adjust
the built-in restrictor located in the replace bae.
The restrictor plate is shipped with all inner rings intact, and when
installed, provides the most vent restriction. There are (2) inner rings
that can be knocked out. The innermost ring knocked out will create
less restriction, and the outer most ring knocked out will create the
least amount of restriction. Closing the bae restrictor will create
more vent exhaust restriction.
Follow FIGURE 7.1 for restrictor plate installation before attaching
venting or through the bae restrictor if venting is already attached.
If you are adjusting the bae restrictor, loosen the (2) thumb screws
to adjust the setting to achieve desired ame appearance.
For vent restriction recommendations and adjustments, see section

11.2 Burner Flame Adjustments
WARNING: To avoid property damage or personal injury, allow the
replace ample time to cool before making any adjustments.
Burner ame appearance and characteristics are aected by
altitude, fuel quality, venting conguration, and other factors. After
installation, this appliance may need additional adjustments to
achieve optimum ame appearance and visual aesthetics.
11.2.1 Burner Venturi
WARNING: VENTURI ADJUSTMENT MUST BE DONE BY A QUALIFIED
SERVICE TECHNICIAN.
NOTE: Burner venturi air shutter settings have been factory set. Refer
to TABLE 11.3.
When this appliance is rst lit, the burner ames will appear blue.
During the rst 15 minutes of operation, ame appearance will
gradually turn to the desired yellow appearance. If the ames remain
blue, or become dark orange with evidence of sooting (black tips),
adjustment of the air shutter opening may be necessary.
Regardless of venturi orientation, closing the air shutter will achieve a
desired yellow ame, but may produce soot on the glass. Opening the
air shutter will cause a short, blue ame that may lift o the burner.
Slight adjustments to the venturi opening will create dramatic results.
Adjust at slight increments until desired look is achieved.
The air shutter on this appliance is factory set for horizontal
terminations, and may need adjustment for natural gas installations,
depending on venting length and conguration. Hussong Mfg.
