HEARTH KIT ASSEMBLY AND INSTALLATION

Kit Assembly

1.Unscrew burner inlet fitting from burner manifold.

2.Place burner manifold in pan with threaded opening facing open knock- out plug (see Figure 8). Make sure the burner ports face downward.

3.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. If using propane/LP gas, see Propane/LP Gas Conversion, pages 10 and 11.

4.If using optional GA9000 kit, go to Op- tional GA9000 On/Off Safety Valve/Pi- lot Kit section for installation instruc- tions. If using optional GA9100 kit, follow instructions included with kit for installation and operation.

5.Using thread sealant on the male threads, install the burner connection fittings into the 1/8" NPT holes on each side of the burner manifold.

6.Press the right and left side burners onto the burner connection fittings. The burner porting should face downward (see Figure 8).

Installation and Gas Connection

1.Place the burner pan assembly in the center of the fireplace floor. Make sure the inlet end of the pan faces the gas supply.

2.Thread the gas supply fitting to the fireplace gas supply pipe. Use thread sealant.

3.Install adapter fitting onto the burner inlet fitting using thread sealant on male threads of burner inlet fitting (see Figure 9). Adjust to most conve- nient position.

4.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.

5.Using the 1/4" x #8 provided, install the cover over the inlet fitting.

OPTIONAL GA9000 ON/OFF SAFETY VALVE/PILOT KIT ASSEMBLY

For additional convenience and safety, or for propane/LP conversion, an optional ON/ OFF safety valve/pilot kit is available. See Accessories, page 19.

Kit Assembly WARNING: You must use a ON/OFF safety valve/pilot kit for propane/LP conversion.

Note: The control cover provided with the GA9000 should be discarded and replaced with the one provided with the log set.

Natural Gas Installation

1.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 rod is facing the front (see Figure 10).
