Do Not Use This Control
in an Application that
is Not Within the Ratings Listed in This
Section. Improper Control Operation May
Result.
Do Not Use This Control
Above 5.5 GPH
CAUTION
A low or erratic power supply could
result in impaired burner operation,
severe delayed ignition or an explosion
inside the heat exchanger resulting in a
burn and/or asphyxiation hazard.
Maintain Specifi ed
Voltage
Beckett DC Burners require a
continuous supply of 21.6 to 30 volts
DC (at 11 amps for Model ADC or 15
amps for Model SDC), measured at
the burner during operation.
Consult other DC burner
manufacturers’ specifi cations for the
correct voltage range.
Special Note: The 7559 Control
shuts the burner down if the input
voltage drops to a sustained level
of 20 volts DC, or below. Operation
resumes at a sustained input
voltage of 21 volts DC, or above.
An automotive or small engine
charging system that is capable of
supplying the required continuous
voltage/amperage is recommended
with certain road equipment, such
as asphalt hot patchers and similar
applications.
This is especially true while
maintaining nominal load temperatures
during idle periods.

The 7559 control draws
40-55mA in the standby
state. If the red control wire is left powered
without a battery charging system, it can
drain a standard 45 Amp hour automotive
battery in four to six weeks.
