GAS LINE AND ELECTRICAL INSTALLATION

GAS LINE AND ELECTRICAL

Gas Line Installation:

NOTE

Plumbing connections should only be performed by a qualified, licensed plumber. Main gas supply must be

off when plumbing gas line to fireplace or performing service.

•Consult all codes. All gas piping must be installed to comply with local codes, or in the absence of local codes, with the latest edition of the National Fuel Gas Code ANSI Z223.1.

•The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressure in excess of 1/2 psi (3.5 kPa).

•The appliance must be isolated from the gas supply piping system by closing the equipment shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.5 kPa).

•Use new black iron or steel pipe. Internally tinned copper or copper tubing can be used per National Fuel Gas Code, section 2.6.3, providing gas meets sulfide limits, and where permitted by local codes.

•An ANSI approved manual shutoff valve must be installed immediately upstream of the gas supply connection to the fireplace

•A sediment trap may be installed upstream of the fireplace to prevent moisture and contaminants from passing

through to the fireplace control and burner. Failure to do so could prevent appliance from operating reliably.

• On some local codes, the gas line must be connected to a gas shut-off valve recessed flush into the wall or floor outside the fireplace. The valve should be controlled by a removable valve key for safety. In this case, remove factory shut-off valve from the flex line and connect line direct to stub.

WARNING

Support the shut-off valve when attaching 1/2” gas line. Use a wrench to hold shut-off valve stationary.

Do not twist the flex line when tightening the 1/2” gas line.

WARNING

Connecting directly to an unregulated propane/L.P.G. tank can cause an explosion. An external regulator must be used on all propane/LPG appliances to reduce the supply tank pressure to 13” w.c. (maximum).

WARNING

Do not connect directly to natural gas 1/2- psi or 2-psi systems. Always make sure the natural gas pressure is

regulated to 10.5 w.c. (maximum) before operating the unit.

•Check gas type. The gas supply must be the same as stated on the appliance’s rating decal. If the gas supply is different from the fireplace, STOP! Do not install the appliance. Contact your dealer immediately.

•To ease installation, a 30” flex line with manual shut-off valve has been installed on this fireplace. Install 1/2” gas line onto shut-off valve.

•Locate the gas line access hole in the outer casing of the fireplace. Remove the screw on the gas line cover plate. Open the fireplace door, insert the gas supply line through the knock out hole on the gas line cover plate, and connect it to the shut-off valve.

•After completing gas line connection, purge air from gas line and test all gas joints from the gas meter to the fireplace for leaks. Use a soap and water solution or a gas sniffer.

•To check gas pressure at valve, turn captured screw counter clockwise 2 or 3 turns and then place tubing to pressure gauge over test point. Refer to Figure 12: Gas Pressure Check at Gas Valve. After taking pressure reading, be sure and turn captured screw clockwise firmly to re-seal. Do not over torque. Check for gas leaks.

WARNING

Do not use open flame to check for gas leaks.
