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.

The flame is so stable it is virtually unaffected

by chimney or poor draft conditions. This makes the SF a smart choice where an appli-

ance has a minimal chimney, or no chimney at all as on rooftop and other outdoor heaters.

The broad flame base is quieter too, due to the precise mixing of air and fuel for optimum combustion. It is compatible with the combus-

tion chamber shape of most furnaces and boilers.

The SF burner can be fired from 2.50 to 5.50

gph with no change of firing components. For special application firing rates, additional com- binations are available from 1.25 to 3.25 gph.
