Beckett SF User Manual

~edett

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.

OIL BURNER

Chassis Plan

. Reduces Investment Up To 65% . Reduces Storage Space Up To 85% . Speeds Service Calls The Beckett Chassis Plan lets you stock a minimum

number of oil burners and still get maximum installation flexibility. The chassis represents up to 90% of the total burner cost, but a single chassis adapts to all firing rates commonly encountered in upgrading and replacement jobs.

To a minimum chassis stock, you add an assortment of air tube combinations. From this assortment, you can choose the precise combination for your application requirements. To complete the installation, simply install the proper support.

Optional Supports

A ONE-PIECE FLAME RETENTION HEAD

The highly stable flame and the intense combustion increases fuel

efficiency as much as 35%.

B STURDY DIE-CAST ALUMINUM HOUSING

The precisely machined, die cast aluminum housing aligns the pump and motor for smooth operation and long coupling life.

C NOZZLE LINE ELECTRODE ASSEMBLY

Self-centering design delivers oil to the nozzle and high voltage electricity to the electrodes. Air flow to the head is controlled and evened out by a static plate for smooth, efficient combustion.

D DRIVE MOTOR

A continuous duty, split phase motor is built for daily hard use and years of trouble free operation. Overload protection standard.

E IGNITION TRANSFORMER

10,000 volts and 23 milliamps positively and smoothly ignite the fuel. No TV interference. Designed for heavy duty continuous operation.

F SOLENOID VALVE

Provides rapid oil cutoff at the end of heat call. This reduces smoke and contributes to quieter, smoother operation.

G CONNECTOR TUBE FITTING

A high quality flare fitting standard with Beckett.
