INSTALLATION

Continued

2.Attach the pilot gas line to the pilot out- let of the gas control valve and tighten. Connect the thermocouple to the rear of the gas control valve. See Figure 11. Do not overtighten. If using propane/LP gas, see Changing Pilot Orifice, page 11.

3.Install the inlet fitting into the inlet opening of the gas control valve (see Figure 12). Use thread sealant on the male pipe threads.

4.Place the burner pan assembly in the center of the fireplace floor. Make sure front of pan faces the room from which you wish to control the appliance.

5.Thread the gas supply fitting to the fire- place gas supply pipe. Adjust to most convenient position.

6.Install the gas connector tube to the gas supply fitting. Carefully shape tube to attach to adapter fitting. Be careful not to cause kinks in tube.

7.Test for leaks following instructions under Testing Burner for Leaks, page 11.

8.Retighten and adjust the location of the gas control as necessary. The gas con- trol should be level, with the control rod to the front.

9.Install cover, provided with log set, to burner pan using screws provided.

10.Install thermocouple, pilot, and ignitor onto valve cover as shown in Figure 13. Use the provided screws.

11.Push the control rod extension onto the “D” shaped control rod through the cen- ter hole in the cover.

12.Install the position decal and control knob making sure to align the marks with the correct stop positions of the gas control. Pilot position will allow the knob to push in about 1/2". Align the decals in the pilot position.

Propane/LP Gas Conversion

To convert to propane/LP gas, the burner inlet fitting and pilot orifice must be re- placed. The propane/LP burner inlet fitting is supplied with the orifice installed for a 24" log set. If you have an 18" set, you must change this orifice also. See Figure 1, page 3 for product identification.

Burner Inlet Fitting

1.Remove the burner inlet fitting from the burner pan assembly (see Figure 14). DO NOT remove the orifice from this fitting. The propane/LP burner inlet fit- ting is included in the hardware kit (see Figure 15).

2.Be sure to use the correct orifice for your appliance. The hardware kit included with this appliance contains two orifices with a cone-like shape. If you have an 18" set, the orifice for the burner inlet fitting is red. If you have a 24" log set, the orifice is already installed inside the fitting. The black orifice will not be used in any multi-side unit and may be discarded.
