In turn, circulator and ignition systems are at service panel before making electrical connections. activated and ignition will begin. Failure to do so could result in death or serious injury.
OPERATING INSTRUCTIONS Operating Instructions Do not set fire visually. Instruments are only reliable method to determine proper air adjustments. Inspect venting system at start of each heating season. Improperly adjusted burner causes soot and high fuel bills Check vent pipe from boiler to chimney for signs because of incomplete combustion of fuel oil.
