Regency P48 Zero Clearance Direct Vent Gas Fireplace 23INSTALLATIONGAS 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 at testpressures equal to or less than 1/2 psig. (3.45kPa). Disconnect piping from valve at pres-sures over 1/2 psig.The manifold pressure is controlled by a regu-lator built into the gas control, and should bechecked at the pressure test point.Note: To properly check gas pressure,both inlet and manifold pressuresshould be checked using the valvepressure ports 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, turn offthe gas valve, disconnect the hose andtighten the screw (clockwise) with a 1/8"flat screwdriver. Note: Screw should besnug, but do not over tighten.S.I.T. VALVE DESCRIPTION1) Gas cock knob2) Manual high/low adjustment3) Pilot Adjustment4) Thermocouple Connection - option5) Outlet Pressure Tap6) Inlet Pressure Tap7) Pilot Outlet8) Main Gas Outlet9) Alternative TC ConnectionPointFor 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 leakswith a soap and water solution or gasleak detector. Do not use open flame forleak testing.PILOT ADJUSTMENTP48-NG System DataFor 0 to 4500 feet altitudeBurner Inlet Orifice Sizes: #27Max. Input Rating 51,000 Btu/hMin.

(CAN1 2.17-M91).GAS LINEINSTALLATIONThe 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 theunit.The gas line connection may be made of rigidpipe, copper pipe or an approved flex connec-tor. (If you are using rigid pipe, ensure that thevalve can be removed for servicing.) Sincesome municipalities have additional local codesit is always best to consult with your localauthorities and the CAN/CGA B149 installationcode.Periodically check the pilot flames. Cor-rect flame pattern has three strong blueflames: 1 flowing around the thermopile,1 around the thermocouple and 1 flowingacross the burner (it does not have to betouching the burner).Note: If you have an incorrect flame pat-tern, contact your Regency dealerfor further instructions.Incorrect flame pattern will have small,probably yellow flames, not coming intoproper contact with the rear burner orthermopile or thermocouple.
