GAS LINE
INSTALLATION
Since some municipalities have additional local codes it is always best to consult with your local authorities and the CAN/CGA B149 installation code.
For USA installations follow local codes and/ or the current National Fuel Gas Code, ANSI Z223.1.
When using copper or flex connectors use only approved fittings. Always provide a union so that gas lines can be easily disconnected for servicing. Flare nuts for copper lines and flex connectors are usually considered to meet this requirement.
IMPORTANT: Always check for gas leaks with a soap and water solution or gas leak detector. Do not use open flame for leak testing.
Periodically check the pilot flames. Correct flame pattern has three strong blue flames: 1 flowing around the thermopile, 1 around the thermocouple and 1 flowing across the burner (it does not have to be touching the burner).
Note: If you have an incorrect flame pattern, contact your Regency® dealer for further instructions.
Incorrect flame pattern will have small, probably yellow flames, not coming into proper contact with the rear burner or thermopile or thermocouple.
GAS PIPE PRESSURE
TESTING
The appliance must be isolated from the gas supply piping system by closing its individual manual
The manifold pressure is controlled by a regulator built into the gas control, and should be checked at the pressure test point.
