Regency U37-LP1 GAS Connection, High Elevation, Aeration Adjustment, LOG SET Installation

INSTALLATION

GAS CONNECTION

The gas connection is a 3/8" NPT 90o elbow. The gas line can be rigid pipe or to make in- stallation easier, use a listed fl exible connector and/or copper tubing if allowed by local codes. Since some municipalities have additional 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 fl ex connectors use only approved fi ttings. Always provide a union so that gas lines can be easily disconnected for burner and/or valve servicing. Flare nuts for copper lines and fl ex connectors are usually considered to meet this requirement.

Important:Always check for gas leaks with a soapandwatersolutionorgasleakdetector. Do not use open flame for leak testing.

Note: Prior to any pressure testing of the gas supply piping system that exceeds test pressures of 1/2 psig, this appliance must be disconnected from the piping system.

HIGH ELEVATION

This unit is approved in Canada for altitude 0 ft. to 4500 ft. (CAN/CGA-2.17-M91). For Natural Gas installations above 4500 ft. follow current CAN/CGA-B149.1.

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 ac- cessed 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 shutter. Open the air shutter for a blue fl ame or close it for a yellower fl ame. The factory setting should be sufficient for most installations.

Clockwise to open,

counter-clockwise to close.

Caution: Carbon will be produced if the air shutter is closed too much.

Note: Any damage due to carboning result- ing from improperly setting the aera- tion controls is NOT covered under warranty.

Note: Aeration Adjustment should only be performedbyanauthorizedRegency® Installer at the time of installation or service.
