DETAILED INSTALLATION STEPS

The appliance is shipped with all gas controls and components installed and pre-wired. Re- move the shipping carton, exposing the front glass door. Remove the top panel. Remove the cardboard from underneath the pressure relief plates. Press in simultaneously the left and right side of the bottom hinged panel, to release it. Lower the bottom hinged panel. Open the two latches (located under the fire- box 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 Figure 53 on page 24.

Step 1. FRAMING

Frame these appliances as illustrated in Figure 9 on page 8, unless the appliance is to be installed in a corner. See Figure 10 on page 8 for corner framing installations. All framing details must allow for a minimum clearance to combustible framing members as shown in

Table 2.

If the appliance is to be elevated above floor level, a solid continuous platform must be constructed.

Headers may be in direct contact with the appliance top spacers but must not be sup- ported 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.

The fireplace should be secured to the side fram- ing members using the unit's nailing flanges - one top and bottom on each side of the fireplace front. See Figure 6. Use 8d nails or their equivalent.

Note: The nailing flanges, combustible members

and screw heads located in areas directly adjacent

to the nailing flanges, are EXEMPT from the 1/2”

clearance to combustible requirements for the

firebox outer wrapper. Combustible framing may be

in direct contact with the nailing flanges and may

be located closer than 1/2” from screw heads and

the firebox wrapper in areas adjacent to the nailing

flanges. Frame the opening to the exact dimensions

specified in the framing details of this manual.

Step 2. ROUTING GAS LINE

Route a 1/2" (13 mm) gas line along the inside of the right side framing as shown in Figure 7. Gas lines must be routed, constructed and made of materials that are in strict accordance with local codes and regulations. All appli- ances are factory-equipped with a flexible gas line connector and 1/2 inch shutoff valve. (See step 6 on page 23).
