HOTOPERATING INSTRUCTIONSSequence Of OperationOn call for heat, thermostat will actuate, completing thecircuit to the boiler. In turn, the ignition systems areactivated and ignition will begin.Figure #14ELECTRONIC LOWWATER CUT OFFPRESSURE RELIEFVALVETOP JACKETPANELIn event of a low water condition, an automatic low watercut-off device will interrupt power between the low watercut-off and burner. Burner remains off until low watercondition is corrected, (i.e., manually restore boiler wateror utilize water feeder device which automatically restoreswater to its normal operating level).Installer - Before putting boiler in operation, testmechanical low water cut-off device for proper operation.While burner is on, open blow-off valve located in lowerportion of cut-off body. This will drain water quickly fromcut-off body and break circuit to burner. If it does not,replace control.! DANGERWater temperatures exceeding 125°F will causesevere burns instantly or death by scalding.28"1/4" SLOTWATERLINEINSPECTIONCOVERLOWER FRONTJACKET PANELBURNERELECTRICALDISCONNECTMOUNTINGSCREWS(BOTH SIDES)Refill boiler to its normal water line.Operating Instructions• Start of heating season have venting system inspected.Check vent pipe from boiler to chimney for signsof deterioration by rust or sagging joints.

See Figure #14.• Safety relief valve should open before steam pressureexceeds 15 psi. reading on the gauge. If this pressureis exceeded and safety relief valve leaks steam whenboiler is operating at normal pressures, immediatelyreplace. Corrosion can build up rapidly at valve seatand prevent its functioning as a safety device.16
