(3.45 kPa). Disconnectpiping from 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 should bechecked using the valve pressure portson 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" pressuretap(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 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 not overtighten.HIGH ELEVATIONThis unit is approved for altitude 0 to 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/or the 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.NOTE: A shutoff / dante valve should besupplied in or near the unit (or as per localcodes) for ease of servicing this appliance.IMPORTANT: Always check for gas leaks witha soap and water solution or gas leak detec-tor. Do not use open flame for leak testing.HZ54E-NG10 SYSTEM DATAMin. Supply Pressure 5" WC (1.25 kpa)Low Setting Man.Pressure1.6" WC (0.40kpa)Max.
