• The replace must be placed directly on a wood or non-
combustible surface (not linoleum or carpet) extending the
entire depth and width of the replace.
• If this appliance is to be installed directly on carpeting, tile,
or other combustible material other than wood ooring, this
appliance shall be installed on a metal or wood panel extending
the full width and depth of the appliance.
• If the appliance is to be installed above oor level, a solid,
continuous platform must be constructed below the appliance.
• Consider the height of hearth nish material (stone, brick, et
cetera) when building a replace platform. The bottom of the
replace must be level with nished hearth to allow for a proper
t of the safety barriers.
• Build the hearth to desired size and height. If a hearth extension
is desired, combustible material may be used.
3.6 Recess Construction
WARNING: All clearances to venting must be maintained.
Mounting a television above a replace has become a common
practice. Television surface temperatures are aected by mantel
depth, ceiling heights, and wall and mantel construction material.
Most television manufacturers specify in their instructions that a
television should not be installed on, near, or above a heat source.
Television location rests solely on the homeowner. It is the
homeowner’s responsibility that the preferred TV mounting and
mantel design will not exceed the listed maximum operation
temperature of their electronic goods.
Tests performed determined that surface temperatures did not exceed
150°F (66°C) when a 4¼ in (108mm) deep recess is constructed above the
replace. See illustrations below.

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.
12.2.1 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 12.3.
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.
12.2.1.1 Venturi Opening Adjustment
IMPORTANT: Slight adjustments to the venturi opening will create
dramatic results. Adjust at slight increments until desired look is
achieved.
1. Remove the safety barrier, glass frame assembly, and glass
media.
2. Remove burner cover (10) screws.
3. Remove burner venturi housing and burner from rebox.
4. Loosen the screw on burner venturi and adjust as necessary. Re-
tighten screw.
