Advanced 24 Vdc Burner Control
Description / Applications
The Beckett GeniSys
24 Vdc primary safety control for oil burners used in special
applications including, but not limited to, water heaters,
pressure washers, crack sealers and portable heaters having
fi ring rates less than 5.5 GPH. The GeniSys
with a suitable cad cell fl ame sensor to control the oil burner
motor, igniter, and optional solenoid valve. It has 24 volt enable
input compatible with mechanical and high limit switches. It
can provide interrupted or intermittent duty ignition, and it has
a 15 second lockout time on fl ame failure.

WARNING
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.
Beckett DC Burners require a
y
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
y
manufacturers’ specifi cations for the
correct voltage range.
Special Note: The 7559 Control
y
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
y
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
y
maintaining nominal load temperatures
during idle periods.

Installation/Operation/Maintenance
WARNING
Incorrect installation or misuse of this
control could result in severe personal
injury or death from heavy smoke,
explosion or fi re.
Please read and understand the manual
supplied with this control. This control
must be installed, adjusted and put into
operation only by a qualifi ed individual or
service agency that is:
Licensed or certifi ed to install and
y
provide technical service to oil
heating systems.
Experienced with all applicable
y
codes, standards and ordinances.
Responsible for the correct
y
installation and commission of this
equipment.
Skilled in the adjustment of oil
y
burners using combustion test
instruments.
The installation must strictly comply with
all applicable codes, authorities having
jurisdiction and the latest revision of
the National Fire Protection Association
Standard for the Installation of Oil-Burning
Equipment, NFPA 31 (or CSA-B139 and
CSA-B140 in Canada) for stationary
equipment.
Regulation by these authorities take
precedence over the general instructions
provided in this installation manual.
Professional
Service Required.
WARNING
All heating equipment must
have HIGH LIMIT controls to
protect against excessive
The control must interrupt electrical
power and shutdown the burner, if

temperature and/or pressure.
Follow the equipment manufacturer’s
wiring diagrams and note all required
safety controls.
Typical safety controls include high
temperature or pressure limits, low
water cutoffs, pressure relief valves
and blocked fl ue sensing switches.
Verify all limit and safety controls are
installed and functioning correctly,
as specifi ed by the manufacturer,
applicable safety standards, codes
and all authorities having jurisdiction.
Insure that the equipment is free of
oil and oil vapor before starting or
resetting the burner.
Do not wire power directly to the
burner motor. Only wire the motor
as shown in Figure 2. If instant
burner heat is required by the
application, purchase or program a
control with a long motor-off delay
time, which will ensure instant heat
if a new call for heat is received
within the motor-off delay time.
Explosion, Fire,
Scald, & Burn Hazard
WARNING
Electrical shock can cause severe
personal injury or death.
Disconnect ALL electrical power to
y
the equipment/burner circuit before
installing or servicing this control.
Provide ground wiring to the
y
equipment, burner and metal control
mounting box.
Perform all wiring in compliance with
y
the National Electrical Code ANSI/
NFPA 70 (Canada CSA C22.1).
