TM 5-3895-374-24-1GP440FGK.LIGHTOILFUELPIPINGSYSTEMSPECIAL NOTEHauck requires the use of oil manifolds which meet NFPA guidelines. NFPA requires two shutoffvalves piped in series in the burner’s main oil line. A low pressure switch must be interlocked withthe burner’s shutoff valves.1.Before attaching fuel lines purge the lines.2.Open all shutoff cocks upstream of the metering valve(s).3.Be sure that the metering valve(s) is in the low fire position.4.Open the pressure gauge cock.5.Slowly adjust the pressure relief valve until the required oil pressure is achieved. Final pump pressure will have to be adjusted to attain desired burner output and stack analysis.

The impeller should rotate toward the blower discharge.7.Inspect and operate the plant exhaust damper control. The exhaust damper should be capable of maintaining aconsistent negative drum front bulk-head pressure of negative 0.2 inches wc to negative 0.5 inches wc from low tohigh firing rates for most applications.(page 3-511)
