Regency ® L676E Direct Vent Gas Fireplace26INSTALLATIONGAS 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 unit is turned OFF.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) Turn the unit ON.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 offthe unit, disconnect the hose and tighten thescrew (clockwise) with a 1/8" flat screwdriver.Note: Screw should be snug, but do notover tighten.PILOT ADJUSTMENTHIGH 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.For USA installations follow local codes and/orthe 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.Important: Always check for gas leaks with asoap and water solution or gas leak detector.Do not use open flame for leak testing.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 or flamesensor.Periodically check the pilot flames. Correctflame pattern has three strong blue flames:1 flowing around the pilot, 1 flowing aroundthe flame sensor and 1 flowing across theburner (it does not have to be touching theburner).L676E-NG SYSTEM DATAMin.
