Operation
Electric Heat Option
The LeeBoy 6150 Conveyor Paver offers an optional
electric heat system to heat the screed, including the
screed extensions, in lieu of the burner system. If
equipped with the 815HD (heavy duty) screed option,
electric screed heat is included. 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 4-48)

Once the heating function has been enabled, the
distribution/control box will apply electrical power to the
heating elements and the heating cycle will begin. The
heating cycle is timed to optimize the heat generated at
the screed plates.
NOTE: Allow the screed (and screed extension) to
heat 15 minutes before beginning to pave.
Lower the screed two inches off the ground
while heating to prevent cold air and wind
from affecting the heating process.
Running the engine at 1800 RPMs
to heat the screed provides the best operating
conditions. Running the engine at lower RPMs
will not allow the screed to heat correctly and may
damage the generator.
Screed Extension:
When using the screed extension(s), light the screed
extension(s) after the main screed burner has been lit
following these additional steps:
1. Lift up on the burner coupler to release ignitor.
(Figure 4-47)
2. Lift ignitor wand, turn valve counterclockwise to
the OPEN position and light the ignitor end with the
torch striker.
3. Replace the lit ignitor wand into the burner tube.
4. Push down on burner coupler to snap back into
place.

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 4-45)
2. When the ames extinguish, turn ALL burner valves
clockwise to the OFF position. (Figure 4-44)
Once the burners have been turned
off, wait at least 30 minutes before relighting.
