28 | Regency ® P121-10/P131-10 Zero Clearance Direct Vent Gas Fireplace|28installationGAS PIPE PRESSURETESTINGThe appliance must be isolated from the gas supplypiping system by closing its individual manual shut-off valve during any pressure testing of the gassupply piping system at test pressures equal to orless than 1/2 psig. (3.45 kPa). Disconnect pipingfrom valve at pressures 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, 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.PILOT ADJUSTMENTPeriodically 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.HIGH ELEVATIONThis unit is approved in Canada for altitude 0 to4500 ft. (CAN1 2.17-M91).GAS LINE INSTALLATIONThe gas line can be brought through either theright, the left side or the bottom of the appliance.The gas valve is situated on the bottom of the unit.The gas line connection may be made of rigid pipe,copper pipe or an approved flex connector. (If youare using rigid pipe, ensure that the valve can beremoved for servicing.) Since some municipalitieshave additional local codes it is always best toconsult with your local authorities and the CAN/CGA B149 installation code.For USA installations follow local codes and/or thecurrent National Fuel Gas Code, ANSI Z223.1.When using copper or flex connectors use onlyapproved fittings. Always provide a union so thatgas lines can be easily disconnected for servicing.Flare nuts for copper lines and flex connectorsare usually considered to meet this requirement.Important: Always check for gas leaks with asoap and water solution or gas leak detector.Do not use open flame for leak testing.Incorrect flame pattern will have small,probably yellow flames, not coming intoproper contact with the rear burner orthermopile or thermocouple.P121/P131-NG10 System DataFor 0 to 4500 feet altitudeBurner Inlet Orifice Sizes: #31Max.
