3.0 Framing

3.1 Appliance Placement Considerations
Read all documentation for your specific installation and design options prior to appliance installation. WARNING: Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies. FIRE HAZARD: Do NOT install this appliance directly on carpeting, vinyl, or any other combustible material other than wood. Note: Unless otherwise noted all clearances / images in this manual are based off of nominal 2″ x 4″ framing being used. · This appliance must be installed on a level surface ca-
pable of supporting the fireplace and venting. If possible, place the fireplace in a position where the vent terminates between two studs, eliminating the need for any additional framing. · This fireplace may be installed in a bedroom. · Please be aware of the large amount of heat this fireplace will produce when determining a location.
3.2 Appliance Installation Options
This appliance offers several design options for managing the heat produced by this fireplace. Note: When deciding on which design option suites your application please review all sections throughout this manual as different design options have different framing, facing, and finishing options and requirements. · Standard Installation will be outlined in this manual in
sections marked `standard installation’ and must be followed if no design options (Komfort Zone Kit) are to be used. The fireplace chamber and ceiling minimum height must be 72″ (1829mm) for standard installations. Only the safety barriers shown in Figure 2.2 are allowed for this installation scenario. · Komfort Zone Kit (KZK) offers the option to redistribute radiant heat through plenum(s). This option allows for combustible facing materials above the fireplace, heat reduction for a TV above the fireplace, and lower mantel clearances. See section 4.0, Heat Management on page 21. If installing a Komfort Zone Kit (#KZK-036 or #KZK-1510A), the framing requirements may be different than the standard dimensions listed in this section. Please reference the manual included with your kit before completing all fireplace framing and other installation considerations. The fireplace chamber and ceiling minimum height must be 82″ (2083mm) for KZK options. Safety barriers shown in Figure 2.2 and Figure 2.3 are allowed for installation when using an approved Komfort Zone Kit. Safety barriers shown in Figure 2.3 are only allowed for use with an approved Kozy Zone Kit. · Kozy Power Vent is a fan- powered mechanical draft vent system (horizontal terminations only) for use with any of the design options listed previously in this section (Standard or Komfort Zone Kit). Reference the #KPV manual for all system requirements. Utilizing the Kozy Power Vent system will not change facing and finishing requirements or safety barrier requirements from the Standard or Komfort Zone Kit design options.

3.3 Floor Support and Protection
· 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 bottom of the fireplace must be level with finished hearth extension for proper fit of a safety barrier.
· 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.
· If the appliance is to be installed above floor level, a solid, continuous platform must be constructed below the appliance.
3.4 Setting the Appliance
· This section outlines information on setting the appliance in the framed opening and starting the installation process.
· Decide on your appliance installation option mentioned in Section 3.2 before setting the appliance. Your framing requirements, clearance to combustibles, and vent configuration will depend upon this decision.
IMPORTANT: If you are using a KZK appliance installation option refer to Section 2.4 for important safety barrier information and Section 4.0 for additional preparation steps that must be completed before setting the appliance in the framed opening. General Procedure Frame your opening based on your selected appliance installa-
tion option. Refer to Section 3.8 for information for the framed opening of the standard installation option. If you are using a KZK installation option refer to the KZK manual for framing. Lay out the path for your vent run before installing appliance. We recommend installing the finishing trim kit. This provides a shadow box around the required safety barrier. Your finishing material will butt up against the finishing trim. Refer to Section 5.2 for installation of finishing trim kit. If you are using the finishing trim kit, this must be installed before the following steps. Install the nailing flanges on the appliance. Refer to Section 3.6 for assembly and installation. The nailing flanges are where you secure your appliance to the framed opening. The framing will be flush with the appliance when it is installed. Assemble and install the top stand-off assembly. Refer to Section 3.5 for more information on the top stand-off assembly. This stand-off assembly provides the necessary thermal protection of the header. Place the fireplace inside the framed opening and secure the appliance into the framing. The fireplace will be flush with the framing. If you use the finishing trim kit, the trim kit will stick past the framing as the finishing material will butt up against the trim. The next steps would involve installing the KZK (if applicable), vent pipe, connect gas line, connect electrical wiring, and finally finishing material.

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.

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. 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 nec-
essary. Re-tighten screws. 3. Reinstall all components previously removed.
