3.8 Wall Enclosure Rough Framing
Note: Unless otherwise noted all clearances / images in this manual are based off of nominal 2" x 4" framing being used.
3.8.1 Rough Framing
WARNING: Provide adequate clearances around air openings into the combustion chamber. Provide adequate clearance in front of the fireplace for barrier removal, component access, gas line installation, service access, etc. CAUTION: Cold air transfer area. The surround fireplace chase must comply with all clearances as outlined in this manual, and be constructed in compliance with local building codes. Outside walls should be insulated to prevent cold air from entering room. Rough-in dimensions outlined in FIGURE 3.4 below are the same for all design options and must be followed. · Floor protection in front of the fireplace is not required.
Combustible material may be used if installing a hearth extension. Consider the thickness of the hearth extension finishing material if building a fireplace platform. The hearth may be flush with the bottom finishing edge of the fireplace. · The bottom of the fireplace must be placed directly on a wood or non-combustible surface (not linoleum or carpet). If this appliance is to be installed directly on carpeting, tile, or other combustible material other than wood flooring, this appliance shall be installed on a metal or wood panel extending the full width and depth of the appliance.

· Framing dimensions should allow for wall covering thickness and fireplace facing materials.
· If masonry (optional) is to be used, prepare the foundation necessary for the full masonry load. A lintel must be used over the top of the appliance to support the added weight of the masonry construction above the fireplace.
3.8.2 Mounting a Television Above a Fireplace and Television Recess Construction
WARNING: All clearances to venting must be maintained. · Mounting a television above a fireplace is a common
practice. Mantel depth, ceiling heights, and wall and mantel construction material all affect television surface temperatures. Most television manufacturers specify in their instructions that a television should not be installed on, near, or above a heat source. · If you want a Television above a fireplace it is highly recommended install the fireplace with the KZK installation design option. Refer to Section 3.2 for more information on the KZK design. Install the plenum discharge above the location of a television. This will help distribute heat from below the TV to above the TV. We also recommend the use of a mantel to deflect heat away from the television. · Television location rests solely on the homeowner. It is the home owner's responsibility that the preferred TV mounting and mantel design will not exceed the listed maximum operation temperature of their electronic goods. · The allowed TV recess of 4-1/4" (108mm) measures from the front of the nominal 2x4 framing to the backside of the finishing material of the pocket.

12.2 Flame Appearance Adjustment
WARNING: To avoid property damage or personal injury, allow the fireplace ample time to cool before making any adjustments. Burner flame appearance and characteristics are affected by altitude, fuel quality, venting configuration, and other factors. After installation, this appliance may need additional adjustments to achieve optimum flame appearance and visual aesthetics.
12.2.1 Burner Venturis
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 first lit, the burner flames will appear blue. During the first 15 minutes of operation, flame appearance will gradually turn to the desired yellow appearance. If the flames 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 flame, but may produce soot on the glass. Opening the air shutter will cause a short, blue flame that may lift off the burner.
12.2.2 Venturi Opening Adjustments
IMPORTANT: Slight adjustments to the venturi opening will create dramatic results. Adjust at slight increments until desired look is achieved. Refer to Table 12.4. 1. Remove the safety barrier, glass frame assembly, glass media, and lava rock (if installed). Remove media tray. 2. Loosen the screw on burner venturis and adjust as necessary. Re-tighten screws. 3.
