SF Oil Burner
1.25 to 5.50 GPH | AC Power

The Beckett SF oil burner uses many of the design features of the popular AF burner for high efficiency over a broad firing range. Both burners feature the proven, one-piece flame retention burner head that locks a highly stable, fuel-efficient flame in place to produce fuel savings as high as 35%. Because smoke is kept to zero in many appliances, heat exchangers stay clean and overall efficiency remains high for years.

Self-centering, delivers oil to the nozzle, high voltage electricity to the electrodes; static plate controls and evens out air flow to the head f(;)rsmooth, efficient combustion.

B. Flame Retention Head

One piece flame-retention burner head. Highly stable and intense combustion increases efficiency by as much as 35 percent.

C. Drive Motor

Continuous duty, split phase motor, built for daily hard use and years of trouble-free operation. Overload protection included.
