TYPICAL INSTALLATION SEQUENCE

The typical sequence of installation is outlined below. 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 brackets. Bend up the appropriate header spacing guides for the drywall/ finish material thickness to be used (see Figure 49). 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 11) Route gas supply line to appliance location.

Step 3. (Page 12) Install the vent system and exterior termination.

Step 4. (Page 24) Field Wiring

a.Millivolt Appliances – Install the operating control switch (not factory provided) and bring in electrical service line for forced air-circulating blower (optional equipment).

b.Electronic Appliances – Field wire and install operating control switch.

Step 5. (Page 25) Install blower kit (optional equipment).

Step 6. (Page 26) Make connection to gas supply.

Step 7. (Page 27) Verifying appliance operation.

Step 8. (Page 28) Install the logs, decorative volcanic stone and glowing embers.

Step 9. (Page 32) Removing and Installing glass door assembly.

Step 10. (Page 32) Adjust burner to ensure proper flame appearance.

Step 11. (Page 34) Install the hoods.

Step 12. (Page 35) Attach Safety in Operation Warnings.

Step 1. Framing

Frame these appliances as illustrated in Figures 13 and 14 on Pages 10 and 11 (Figure 14 applies to corner framing installations only). 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 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 3. Install the Vent System

General Information

These instructions should be used as a guideline and do not supersede local codes in any way. Install venting according to local codes, these instructions, the current National Fuel Gas Code (ANSI-Z223.1) in the USA or the current standards of CAN/CSA-B149.1 in Canada.

Ensure clearances are in accordance with local installation codes and the requirements of the gas supplier.

Dégagementconformeauxcodesd'installation locaux et aux exigences du foumisseunde gaz.

Use only approved venting components.

See Approved Vent Components on Page 2.

These fireplaces must be vented directly to the outside.

12

The vent system may not service multiple appliances, and must never be connected to a flue serving a solid fuel burning appliance. The vent pipe is tested to be run inside an enclosed wall (such as a chase). There is no requirement for inspection openings in the enclosing wall at any of the joints in the vent pipe.

Installation of Vent Restrictor

A vent restrictor may be needed with this appliance. The restrictor is installed in the appliance top flue outlet as shown in Figure 16, either before adding vent, from above, or after installation of vent from below, within the firebox. The restrictor is self securing through a positive friction fit.

Determine the venting for the appliance. If the vent run will include at least 8 feet of vertical rise, then install the restrictor in the appliance collar before connecting any vent (Refer to Figure 16). Place the second restrictor inside the fixed restrictor.

Note: The restrictor is included within the firebox.
