HIGH ELEVATION

This unit is approved in Canada for altitude 0 to 4500 ft. (CAN1 2.17-M91).

GAS LINE

INSTALLATION

The gas line can be brought through either the right, the left side or the bottom of the appliance. The gas valve is situated on the bottom of the unit.

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 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 soap and water solution or gas leak detector. Do not use open flame for leak testing.

PILOT ADJUSTMENT

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 flamepattern, 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.

Themanifoldpressureiscontrolledbyaregulator built into the gas control, and should be checked at the pressure test point.

Note: To properly check gas pressure, both inlet and manifold pressures should be checked using the valve pressure ports on the valve.

1)Make sure the valve is in the "OFF" position.

2)Loosen the "IN" and/or "OUT" pressure tap(s), turning counterclockwise with a 1/8" wide fl at screwdriver.

3)Attach manometer to "IN" and/or "OUT" pressure tap(s) using a 5/16" ID hose.

4)Light the pilot and turn the valve to "ON" position.

5)The pressure check should be carried out with the unit burning and the setting should be within the limits specifi ed on the safety label.

6)When fi nished reading manometer, turn off the gas valve, disconnect the hose and tighten the screw (clockwise) with a 1/8" fl at screwdriver. Note: Screw should be snug, but do not over tighten.

Point

The gas line connection may be made of rigid pipe, copper pipe or an approved flex connector. (If you are using rigid pipe, ensure that the valve can be removed for servicing.) Since some municipalities have additional local codes it is always best to consult with your local authorities and the CAN/CGA B149 installation code.

GAS PIPE PRESSURE

TESTING

The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig. (3.45 kPa). Disconnect piping from valve at pressures over 1/2 psig.
