Beckett SF User manual

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.

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.

AONE-PIECE FLAME RETENTION HEAD
The highly stable flame and the intense combustion increases fuel
efficiency as much as 35%.
BSTURDY DIE-CAST ALUMINUM HOUSING
The precisely machined, die cast aluminum housing aligns the
pump and motor for smooth operation and long coupling life.
CNOZZLE 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.
DDRIVE MOTOR
A continuous duty, split phase motor is built for daily hard use and
years of trouble free operation. Overload protection standard.
EIGNITION TRANSFORMER
10,000 volts and 23 milliamps positively and smoothly ignite the
fuel. No TV interference. Designed for heavy duty continuous
operation.
