Disconnect piping from valve atpressures over 1/2 psig.The manifold pressure is controlled by a regulatorbuilt into the gas control, and should be checkedat the pressure test point.Note: To properly check gas pressure, bothinlet and manifold pressures shouldbe checked using the valve pressureports on the valve.1) Make sure the valve is in the "OFF"position.2) Loosen the "IN" and/or "OUT" pressuretap(s), turning counterclockwise with a1/8" wide flat 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 outwith the unit burning and the setting shouldbe within the limits specified on the safetylabel.6) When finished reading manometer, turnoff the gas valve, disconnect the hose andtighten the screw (clockwise) with a 1/8" flatscrewdriver. Note: Screw should be snug,but do not over tighten.S.I.T. VALVE DESCRIPTION1) Gas on/off knob2) Manual high/low adjustment3) Pilot Adjustment4) Thermocouple Connection - option5) Outlet Pressure Tap6) Inlet Pressure Tap7) Pilot Outlet8) Main Gas Outlet9) Alternative TC ConnectionPointWhen using copper or flex connectors use onlyapproved fittings. Always provide a union sothat gas lines can be easily disconnected forservicing. Flare nuts for copper lines and flexconnectors are usually considered to meet thisrequirement.Important: Always check for gas leaks with asoap and water solution or gas leak detector.Do not use open fl ame for leak testing.PILOT ADJUSTMENTHIGH ELEVATIONThis unit is approved in Canada for altitude 0to 4500 ft. (CAN1 2.17-M91).GAS LINEINSTALLATIONThe gas line can be brought through eitherthe right, the left side or the bottom of theappliance. The gas valve is situated on thebottom of the unit.The gas line connection may be made of rigidpipe, copper pipe or an approved flex connector.(If you are using rigid pipe, ensure that the valvecan be removed for servicing.) Since somemunicipalities have additional local codes it isalways best to consult with your local authoritiesand the CAN/CGA B149 installation code.For USA installations follow local codes and/orthe current National Fuel Gas Code, ANSIZ223.1.Periodically check the pilot fl ames. Correctflame pattern has three strong blue fl ames:1 flowing around the thermopile, 1 aroundthe thermocouple and 1 fl owing across theburner (it does not have to be touching theburner).Note: If you have an incorrect flame pattern,contact your Regency ® dealer forfurther instructions.Incorrect flame pattern will have small,probably yellow fl ames, not coming intoproper contact with the rear burner orthermopile or thermocouple.
