Gas Line Installation
Remote ON/ OFF Switch Installation
When purging the gas lines, the front glass must be removed.
The gas pipeline can be brought in through the side of the fireplace as well as the bottom. Knockouts are provided on the bottom behind the valve to allow for the gas pipe installation and testing of any gas connection. It is most convenient to bring the gas line in from the rear right side of the valve as this allows fan installation or removal without disconnecting the gas line.
The gas line connection can be made with properly tinned 3/8” copper tubing, 3/8” rigid pipe or an ap- proved flex connector. Since some municipalities have additional local codes, it is always best to consult your local authority and the
For USA installations consult the current National Fuel Gas Code, ANSI Z223.1/NFPA 54.

Always check for gas leaks with a mild soap and water solution applied with a brush no larger than 1” (25 mm). Never apply soap and water solution with a spray bottle. Do not use an open flame for leak testing.
The fireplace valve must not be subjected to any test pressures exceeding 1/2 p.s.i. Isolate or disconnect this or any other gas appliance control from the gas line when pressure testing.
The gas control is equipped with a captured screw type pressure test point; therefore, it is not necessary to provide a 1/8” test point upstream of the control.
When using copper or flex connector use only ap- proved fittings. Always provide a union when using black iron pipe so that the gas line can be easily disconnected for burner or fan servicing. (Fig. 6) See the gas specifications for pressure details and ratings.
Do not wire the remote ON/OFF wall switch for this gas appliance into a 120 V power supply.
1.Thread the wiring through the electrical knockout located on either side of the unit. Take care not to cut the wire or insulation on metal edges. Ensure the wire is secured and protected from possible damage. Run one end to the gas control valve and the other end to the conveniently located wall switch.
2.Attach the wire to the ON/ OFF switch and install the switch into the receptacle box. Attach the cover plate to the switch.
3.Connect the wire to the gas control valve. (Fig. 7)
