Regency® P33E-4 Zero Clearance Direct Vent Gas Fireplace 33INSTALLATIONGAS 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 switch is in the "OFF" position.2) Loosen the "IN" and/or "OUT" pressure tap(s),turning counterclockwise with a 1/8" wide flatscrewdriver.3) Attach manometer to "IN" and/or "OUT"pressure tap(s) using a 5/16" ID hose.4) Light the pilot by turning the switch to "ON"position.5) The pressure check should be carried out withthe unit burning and the setting should be withinthe limits specified on the safety label.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.HIGH ELEVATIONThis unit is approved in Canada for altitudeto 4500 ft.
