However, each installation is unique and may result in variations to the steps described. See the Page numbers references in the following steps for detailed procedures. Step 1. (Page 9) Construct the appliance framing. Position the appliance within the framing and secure with nailing flanges. Step 2. (Page 12) Route gas supply line to appliance location. Step 3. (Page 13) Install the vent system and exterior termination. Step 4. (Page 25) Field Wiring .. a. Millivolt Appliances – Install the OFF/ON burner control switch and bring in electrical service line for forced air-circulating blower (optional equipment). .. b. Electronic Appliances – Connect 120 VAC electrical power to the appliance receptacle. Step 5. (Page 26) Install blower kit (optional equipment). Step 6. (Page 27) Make connection to gas supply. Step 7. (Page 28) Verify appliance operation. Step 8. (Page 28) Install the logs, decorative volcanic stone and glowing embers. Step 9. (Page 30) Install glass door assemblies. Step 10. (Page 30) Adjust burner primary air shutter to achieve proper flame appearance. Step 11. (Page 31) Install the decorative trim and hoods. Step 12. (Page 32) Attach Safety in Operation Warnings. The appliance is shipped with all gas controls and components installed and pre-wired. 1. Remove the shipping carton. Remove the shipping pad, exposing the front glass door. 2. Open the two latches (located under the firebox floor) securing the glass door. Remove the door by tilting it outward at the bottom and lifting it up. Set the door aside protecting it from inadvertent damage. See Removing Glass Panels on Page 30. 2. Remove the top louvered panel and locate the pressure relief plates. 3. Lift the pressure relief plates and remove the cardboard from beneath each plate (be careful not to damage the white gasket). See Figure 10. * NOTE: INSTALLATION DIAGRAMS AND INSTRUCTIONS SHOW THE FRONT OF THE APPLIANCE AS THE SIDE WHICH HAS VALVE ACCESS, EXCEPT WHERE NOTED. Step 1. Framing Frame these appliances as illustrated in Figures 12 and 13 on Pages 10 and 11. All framing details must allow for a minimum clearance to combustible framing members as shown in Table 6 on Page 8. If the appliance is to be elevated above floor level, a solid continuous platform must be constructed below the appliance. Headers may be in direct contact with the appliance top spacers but must not be supported by them or notched to fit around them. All construction above the appliance must be self-supporting. DO NOT use the appliance for structural support. Side Nailing Flanges The fireplace should be secured to the framing at the side(s) of the appliance using the factory-provided nailing flanges. Install the 8 nailing flanges as shown in Figure 11 using the existing screws. Position the fireplace within the framing. When required, the tabs may be bent 90 degrees by hand or with the assistance of a hammer. Use wood screws to secu...
