Figure 18. Electric Burner System
Once the burner shuts off automatically, it will not
restart until the cycle button is again depressed.
To shut the system down: Close the main fuel sup-
ply valve at the tank.
Increase the thermostat setting 50 to 75ºF higher
and push the start button. This will bring on the main
burners and quickly burn off all of the fuel in the line
between the tank and the control box. The pilot burn-
ers may continue to burn for a short time after the
main burners cut off. Do not draw material from the
tank as long as there is a flame present.
Close the exhaust stack dampers.
Electric Driven Burner Operation
Open the dampers in the exhaust stacks.
Circulate the asphalt in the tank before lighting the
burners. If the asphalt is too cold to pump, start circu-
lating the material in the tank as soon as possible after
lighting the burner.
To light the burner, turn on the “Lower Burner
Power” switch.
If upper burner operation is desired, turn on the “Up-
per Burner Power” switch.
Do not heat the material higher than the spraying
temperature recommended by the asphalt supplier.
To shut down the burners, turn off the burner power
switches.
