INSTALLATION
GAS CONNECTION
The gas connection is a 3/8" NPT 90o elbow. The gas line can be rigid pipe or to make installation easier, use a listed flexible connec- tor and/or copper tubing if allowed by local codes. Since some municipalities have addi- tional local codes it is always best to consult with your local authorities and the CAN/CGA B149 installation codes. 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 burner and/or valve 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.
Note: Prior to any pressure testing of thegas supplypiping system that exceeds test pressures of 1/2 psig, this appliance must be dis- connected from the piping sys- tem. If test pressures equal to or less than 1/2 psig are used then this appliance must be isolated from the piping system by clos- ing its individual manual

AERATION
ADJUSTMENT
The burner aeration is factory set but may need adjusting due to either the local gas supply, air supply or altitude.
Natural Gas: 1/4" open
Propane: 3/8" open
The aeration adjustment gears are located on the right side of the burner box and can be accessed from the side or from the front when the louvers are removed.
To adjust the aeration: use the allen key to turn the turning gear which will adjust the air shut- ter. Open the air shutter for a blue flame or close it for a yellower flame. The factory setting should be sufficient for most installations.
Clockwise to open,
Caution: Carbon will be produced if the air shutter is closed too much.
Note: Any damage due to carboning re- sulting from improperly setting the aeration controls is NOT cov- ered under warranty.
Note: Aeration Adjustment should only be performed by an authorized Regency Installer at the time of installation or service.
