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.

Environmental Ratings:

•Storage and Operating Ambient Temperature: -40°F to +160°F (-40°C to +71°C)

•Moisture: 5 to 95% RH, condensing

WARNING MaintainVoltage Specified

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.

yBeckett 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.

yConsult other DC burner manufacturers’ specifications for the correct voltage range.

ySpecial 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.

yAn 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.

yThis is especially true while maintaining nominal load temperatures during idle periods.
