Operation
NOTE: Adjust the pressure regulator valve IN or OUT
until the propane pressure regulator gauge
reads 15 pounds.
NOTE: It may be necessary to maintain low heat on
the screed if paving on a cool, windy day.
Reduce pressure on the propane pressure
regulator gauge to two pounds (.14 bar) in
these conditions. DO NOT attempt to regulate
the burner with the burner valve.
After the main screed (and screed extension) has
heated for 15 minutes:
1. Turn the propane tank valve clockwise to the
CLOSE position to allow the propane system to
burn off all the gas. (Figure 4-33)
2. When the ames extinguish, TURN OFF ALL burner
valves clockwise to the OFF position. (Figures
4-32 through 4-35)
Electric Screed Heat (Option)
The LeeBoy 8515D Conveyor Paver offers an optional
electric heat system to heat the screed, including the
screed extensions, in lieu of the burner system. A
hydraulically-driven generator powers the electric heat
control box mounted in the center on the rear side of the
machine. This control box is where you will select the
heating function before you begin to pave. It is easily
accessible to the screed operator when a heating cycle
is needed. (Figure 4-36).
