The appliance is approved with zero clearance to combustible materials on all sides (as detailed in Table 5), with the following exception: When the unit is installed with one side ﬂush with a wall, the wall on the other side of the unit must not extend beyond the front edge of the unit. In addition, when the unit is recessed, the side walls surrounding the unit must not extend beyond the front edge of the unit (see Figure 3).

*Note: 3 in. (75 mm) above any horizontal/inclined vent component.

**Note: See Page 9, Step 1 for clearance requirements to the nailing ange located at each side

of the unit and any screw heads adjacent to it.

Hearth Extension - A hearth extension is not

required with this appliance. If a hearth extension is used, do not block the lower control compartment door. Any hearth extension used is for appearance only and does not have to conform to standard hearth extension installation requirements.

Shelf Height - To provide for the lowest pos-

sible shelf surface, use the alternate rear vent outlet, the venting attached to the top vent should be routed in a way to minimize obstructions to the space above the appliance. Do not insulate

the space between the appliance and the area above it (see Figure 8). The minimum height

from the base of the appliance to the underside of combustible materials used to construct a utility shelf in this fashion is shown in Figure 8.

Wall Finishes / Surrounds / Mantels

Note: Combustible wall ﬁnish materials and/or surround materials must not be allowed to encroach the area deﬁned by the appliance front face (black sheet metal). Never allow combus-

tible materials to be positioned in front of or overlapping the appliance face (see Figure 65

on Page 35).

DETAILED INSTALLATION STEPS

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 and Installing Glass Panels on Page 33.

3. Remove the top louvered panel and locate the pressure relief plates

(see Figure 11).

4. Lift the pressure relief plates and remove the cardboard from beneath each plate (be careful not to damage the white gasket).

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

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 10. (Page 33) Install glass door assembly.

Step 1. FRAMING

Frame these appliances as illustrated in Figures 13 and 14 on Pages 11 and 12. All framing

details must allow for a minimum clearance to combustible framing members as shown in Table 5 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 when they are bent up vertically maintaining the 3" clearance to the ﬁreplace top, 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.

The ﬁreplace should be secured to the side framing members using the unit's nailing ﬂanges - one top and bottom on each side of the ﬁreplace front. See Figure 12. Use 8d nails or their equivalent.

Step 1. (Page 10) Construct the appliance framing. Position the appliance within the framing and secure with nailing brackets. Bend up the appropriate header spacing guides for the drywall/ﬁnish material thickness to be used (refer to Figure 62, page 33). Bend up the outer pair for 1/2" materials and the inner pair for 5/8" materials. Bend out the appropriate nailing ﬂanges for the drywall/ﬁnish material to be used. Nailing ﬂanges are provided for ﬂush framing, 1/2 inch and 5/8 inch framing depths (see Figure 12).

Step 2. (Page 13) Route gas supply line to appliance location.

Step 3. Preparing the appliance vent collar (Page 13).
