WILL I VOID THE WARRANTY ON THE DIESEL BURNER IF I USE BIO-DIESEL?
Use of bio-diesel fuel exceeding B5 will void the warranty on the burner and related failure(s).
The burners are designed to run on B5 bio-diesel fuel or #1 and #2 diesel fuel.
SHOULD I BE CONCERNED ABOUT ASPHALT MATERIAL OVERSPILL ON THE TOP CAPS
OF THE HOPPER WALLS?
Yes, Asphalt must be cleared away from top of hopper walls before closing loading doors.
CAN I RUN THE TACK BURNER WITHOUT MATERIAL INSIDE THE TACK TANK?
No, The tack tank burner should never be turned on when there is no tack material inside the tank.
WHY IS IT SO IMPORTANT TO KEEP THE HOPPER FLOOR CLEAN? HOW CAN I EXTEND
THE USEFUL LIKE OF MY PATCHER?
Failure to clean the bottom of the hopper shortens the life of your asphalt hot patcher and prevents the
patcher from working as designed. Built up asphalt acts as an insulator and prevents the heat in the burner
box from evenly heating the material inside the hopper. Not only does built up asphalt prevent the material
from heating as designed, it forces too much heat to build up in the burner box. The heat cannot escape
through the layers of built up asphalt so it escapes into the burner and can result in problems like a melted
CAD cell. Once the material has reached the "set temperature" of the controller, the burner cycles on and off
periodically as the temperature of the material inside the hopper drops 10 degrees Fahrenheit. If the heat is
not allowed to radiate through the hopper floor and warm the material inside the hopper, the controller won't
get the message to turn off and the burner will run excessively.
The general rule of thumb is to not run the burner any hotter than
necessary. Most customers have success applying hot mix at a temperature
of approximately 240 to 270 degrees Fahrenheit. The useful life of the
machine will be extended and less fuel will be used if the temperature
controller is set at a lower temperature.
The controller temperature should be set on the lower end of the recommended range -- see the supplier of
the asphalt material for the appropriate application temperature range. If the asphalt material gets too hot,
the operator may notice blue smoke emanating from the asphalt. This means that oils are being burned from
the material and the diesel burner is running too hot. If this is observed, lower the temperature on the hopper
controller (located inside the electrical enclosure) and monitor the material to ensure that the material is not
too hot. The temperature change will not be observable immediately -- monitor every 15 minutes and make
additional adjustments if necessary.
