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" pressure tap(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, turn off thegas valve, disconnect the hose and tighten thescrew (clockwise) with a 1/8" flat screwdriver.Note: Screw should be snug, but do notover tighten.SIT 829 VALVE DESCRIPTION1) Gas on/off knob2) Electronically Operated Hi/Lo3) Pilot Adjustment4) Thermocouple Connection - option5) Outlet Pressure Tap6) Inlet Pressure Tap7) Pilot Outlet8) Main Gas Outlet9) Alternative TC Connection PointHIGH ELEVATIONThis unit is approved in Canada for altitude 0to 4500 ft. (CAN1 2.17-M91).GAS LINEINSTALLATIONSince some municipalities have additionallocal codes it is always best to consult withyour local authorities and the CAN/CGA B149installation code.PILOT ADJUSTMENTPeriodically check the pilot fl ames. Correctflame pattern has three strong blue fl ames:1 fl owing 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.IMPORTANT: Always check for gas leakswith a soap and water solution or gas leakdetector. Do not use open fl ame for leaktesting.For USA installations follow local codes and/or the current National Fuel Gas Code, ANSIZ223.1.When 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.
