Test Pressures Equal To or Less Than 1/2 PSIG

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.

HEARTH KIT ASSEMBLY AND INSTALLATION

Kit Assembly

Note: The following instructions apply to both standard single bar burners, as well as dual flame “U” style burners. Be sure all pipe threaded connections are tight, and have thread compound to prevent leaks.

1.Determine which side the gas line will be coming into the fireplace.

2.Using a hammer and screw driver, re- move knock-out plug from the side of the pan that corresponds to the gas line (see Figure 8).

3.Unscrew burner inlet fitting from burner manifold (see Figure 9).

4.Place burner manifold in pan with threaded opening facing open knock- out plug.

5.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, page 10.

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

7.If using optional GA9050 series kit, go to Optional GA9050 Series On/Off Safety Valve/Pilot Kit section for installation in- structions. If using optional GA9150 se- ries kit, follow instructions included with kit for installation and operation.

Installation and Gas Connection

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

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 10).

4.Install the gas connector tube to the gas supply fitting. Carefully shape tube to attach to adapter fitting.

OPTIONAL GA9050 SERIES 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 20.

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

Natural Gas Installation

1.Thread the gas control valve onto the burner inlet fitting (see Figure 11). 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 11).
