Connect the Gas Supply

Gas Supply Requirements

ALL INSTALLATIONS MUST COMPLY WITH LOCAL CODE OR IN THE ABSENCE OF LOCAL CODE, MUST COMPLY WITH THE MOST RECENT EDITION OF THE NATIONAL FUEL GAS CODE ANSI Z223.1/NFPA 54 OR CAN-B149.

Shutoff Valve

All codes require a gas shutoff valve (gas cock) and union to be installed in the supply line and in the same room as the appliance. This allows for the disconnection of the fireplace for servicing and maintenance. See fig. 25.

A T-handle gas shutoff valve is required in Massachusetts in compliance with Code 248CMR.

The fireplace and gas control valve must be disconnected from the gas supply piping during any pressure testing of the system at test pressures in excess of 1/2 psig. For pressures lower than 1/2 psig, isolate the gas supply by closing the manual shutoff valve.

Control Valve Connection

The gas supply line connection is made to the left side of the valve. The gas supply line should be a minimum 3/8" diameter, or the appropriate size to provide sufficient gas pressure to the valve regard- less of the input setting.

The use of flexible gas appliance connectors is acceptable in many areas in the U.S. In Canada, methods vary depending on local code. If local codes permit, use flexible gas line for ease of installation and service. For those locales where flexible gas lines are not permitted, use the 3/8” iron fitting to make the connection at the left side of the Control Valve. See Figures 25 and 26.

Secure all joints tightly using appropriate tools and sealing compounds (for propane units, be sure to use compounds that are propane resistant). Turn on gas supply and test for gas leaks using a soapy water solution. Never use an open flame to check for leaks.

Leak test:

•Mix a 50-50 solution of water and dish soap.

•Light appliance- see lighting instructions on page 23 of this manual or on the fireplace’s rating plate.

•Brush or spray all joints and connections with the soapy water solution.

•If bubbles appear at any connection or seam or a gas odor is detected, immediately turn gas control knob to the OFF position.

Tighten or reconnect the leaking joint and retest for any gas leaks.

Gas Pressure

Proper gas pressure provides a consistent flow of gas to the appliance and is instrumental in checking for gas leaks. The gas control valve on the fireplace is equipped with pressure test points for gauge connections. The gauge connections are located on the front of the valve under the On/Off/ Pilot knob. Gauge connections are identified by:

•IN/E for inlet or supply pressure (the amount of gas coming to the valve.)

•OUT/A for manifold pressure (the amount of gas that is coming out of the valve to the burner.)
