Regency® L676S Direct Vent Gas Fireplace28INSTALLATIONINSTALLATIONGAS PIPE PRESSURETESTINGThe appliance must be isolated from the gassupply piping system by closing its individualmanual shut-off valve during any pressuretesting of the gas supply piping system attest pressures equal to or less than 1/2 psig.(3.45 kPa). 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 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 outwith the unit burning and the setting shouldbe within the limits specifi ed on the safetylabel.6) When finished reading manometer, turn off thegas valve, disconnect the hose and tighten thescrew (clockwise) with a 1/8" fl at screwdriver.Note: Screw should be snug, but do notover tighten.SIT 820 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 Connection PointHIGH ELEVATIONThis unit is approved in Canada for altitude 0 to4500 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.For USA installations follow local codes and/or the current National Fuel Gas Code, ANSIZ223.1.When using copper or fl ex connectors use onlyapproved fi ttings. Always provide a union sothat gas lines can be easily disconnected forservicing. Flare nuts for copper lines and fl exconnectors are usually considered to meet thisrequirement.IMPORTANT: Always check for gas leakswith a soap and water solution or gas leakdetector. Do not use open flame for leaktesting.Periodically check the pilot flames. Correctflame pattern has three strong blue flames:1 flowing around the thermopile, 1 aroundthe thermocouple and 1 flowing 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 flames, not coming intoproper contact with the rear burner orthermopile or thermocouple.PILOT ADJUSTMENTL676S-NG1 SYSTEM DATAMin.
