1.Close manual shutoff valve (see Fig- ure 7).

2.Pressurize supply piping system by either using compressed air or opening main gas valve located on or near gas meter.

3.Check all joints from gas meter to manual shutoff valve (see Figure 7). Apply mix- ture of liquid soap and water to gas joints. Bubbles forming show a leak.

4.Correct all leaks at once.

3.Place burner manifold in pan with threaded opening facing open knock-out plug. Note: If using propane/LP gas, see Propane/LP Gas Conversion, page 10.

4.Thread the gas control valve onto the burner inlet fitting (see Figure 10). Use thread sealant on the male threads of the burner inlet fitting. Hold the burner inlet fitting with a wrench to prevent overtightening the connection to the burner. Make sure the control knob is facing the front (see Figure 10).

5.Using burner clamp, screw, and nut pro- vided, assemble clamp to pan (“U” style burners only). This will hold the burner manifold in place (see Figure 9).

6.Attach the pilot gas line to the pilot outlet of the gas control valve and tighten. Connect the thermocouple to the terminal block on the gas control valve. See Figure 11. Do not over- tighten. If using propane/LP gas, see Changing Pilot Orifice, page 11.

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

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

9.Thread the gas supply adaptor to the fireplace gas supply pipe. Adjust to most convenient position.

10.Install the gas connector tube to the gas supply adaptor. Carefully shape tube and attach to gas inlet fitting (see Figure 12). Be careful not to cause kinks in tube.

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

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