Do Not Use This
Control Above 5.5 GPH
CAUTION
The 7556 control
draws 60-75mA 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 two to four weeks.
NOTICE
*
Maintain Specifi ed
Voltage
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 continuous
supply of 11 to 16 volts DC (at 15 amps for
Model ADC or 25 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 7556 Control shuts the
burner down if the input voltage drops to
a sustained level of 10 volts DC, or below.
Operation resumes at a sustained input
voltage of 11 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.
