SF Oil Burner

The Model SF 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.
