Natural gas models will have a manifold pressure of approximately 3.5" w.c. (.871kPa) at the valve outlet with the inlet pressure to the valve from a minimum of 4.5" w.c. (1.120kPa) for the purpose of input adjustment to a maximum of 14.0" w.c. (3.484kPa). Propane gas models will have a manifold pressure approximately 10.0" w.c. (2.49kPa) at the valve outlet with the inlet pressure to the valve from a minimum of 10.8" w.c. (2.68kPa) for the purpose of input adjustment to a maximum of 14.0" w.c. (3.484kPa). Figure 8 GAS SUPPLY (CONT) Page 10 19400-3-0406 Framing dimension "A" includes a three inch clearance for standoffs on firebox. Framing and Finishing 1. Choose unit location. 2. Frame in fireplace with a header across the top. It is important to allow for the finished face thickness when setting the depth of the frame. See Figures 9 & 11. 3. Attach fireplace to framing using (4) adjustable nailing flanges. Preset depth to suit facing material (adjustable to 1/2", 5/8" or 3/4" depths). 4. Use (8) 1/2" hex-head screws supplied in hardware package to screw through slotted holes in nailing flanges, then screw into pre-drilled holes on fireplace side. Measure from face of fireplace to face of the nailing flanges to determine final depth. Vent Pipe Clearance Note: Maintain one inch (1") of clearance around vertical vent pipe. Follow the B-Vent system instructions for installation requirements and clearances. Failure to follow the B-Vent manufacturer's instructions may cause improper draft and possible fire hazard. Figure 10 BTO COMBUSTIBLES NAIL OR OTHER SUITABLE FASTENER MOUNTING BRACKETS Install the Fresh Air Kit - BVA1 A fresh air kit is available as an optional feature with this appliance. The fresh air kit helps to decrease the amount of room air taken by utilizing outside air for combustion. It is strongly recommended that it be installed. Installation of the fresh air kit should be performed at the framing stage of the fireplace installation. The fresh air kit installs on the left side of the fireplace. To install the BVA1 fresh air kit, refer to the installation instructions provided with the kit. Note: The outside air kit can terminate at any level with the exception that it must terminate at least 1 ft below the vent termination cap. The fresh air kit inlet hood should be positioned at least 2 ft above the ground level, in a manner that will not allow snow, leaves, etc. to block the inlet. WARNING: Exhaust products of gasoline engines are hazardous. The outside air must not be taken from a garage space, attic spaces, basements, or above the roofing where other heating appliance, fans, or chimneys exhaust or utilize the air. Figure 9 Framing (Figure 11) Fireplace framing can be built before or after the fireplace is set in place. Framing should be positioned to accommodate wall covering and fireplace facing material. The fireplace framing should be constructed of 2 x 4 lumber or heavier. The framing headers may rest on the fireplace standoffs. Refer to Figure 11 for minimum framing dimensions. CAUTION: MEASURE FIREPLACE DIMENSIONS AND VERIFY FRAMING METHODS, AND WALL COVERING DETAILS BEFORE FRAMING CONSTRUCTION BEGINS.

Figure 11 Attention: Add 3-3/4" to “A” dimensions when using a flush mantel base. Attention: If a base or mantel is not used and the appliance is installed directly on carpeting, tile or other combustible material other than wood flooring, it shall be installed on a metal or wood panel extending the full width and depth of the appliance. The vertical dimension in Figure 11 must be adjusted when a metal or wood panel is placed beneath the appliance. Finishing (Figure 12) Finish the walls with the material of your choice.
