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 12. 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 13). Use thread sealant on the male pipe threads.

4.Place the burner pan assembly in the center of the fireplace floor. Make sure the front of pan faces forward.

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 to burner pan using screws provided.

10.Install thermocouple, pilot, and ignitor onto valve cover as shown in Figure 14. 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" or 30" 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. DO NOT remove the orifice from this fitting. The pro- pane/LP burner inlet fitting 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; for a 30" set, it is black. If you have a 24" log set, the orifice is al- ready installed inside the fitting.

3.For an 18" or 30" set, use a 10mm socket or nut driver to remove the ori- fice from the propane/LP burner inlet fitting. Choose the correct orifice for your log set size and install in place of the orifice you just removed.

4.Using thread sealant (resistant to the action of propane/LP gas) on larger end of fitting, screw the burner inlet fitting through hole and into burner manifold. Tighten using a wrench.

5 . Follow steps 1 through 12 under Natu- ral Gas Installation, pages 9 and 10.
