Only under very bad conditions is it acceptable to operate the burners without circulating material in the
tank. However, if it is absolutely necessary to operate burners before the asphalt pump is free, take the
Check as usual to insure flues are covered by a minimum of 6 in of material for the full length.
Do not operate hydraulic system at more than 1500 psi except when attempting to free asphalt
Turn blower motor control valve on before engaging PTO and increasing hydraulic system
Free asphalt pump by applying heat to the housing and start circulating tank as soon as possible.
DIRECTIONS FOR LOW PRESSURE BURNERS
Open stack cover.
Set controls for Circulate in Tank.
Suspend thermometer from manhole if material does not cover thermometer well.
Read detailed instructions in manual.
Use kerosene or fuel oil only
Circulate material approximately 1.50 gal per minute
Set air pressure 1-1/2 to 2 psi Set fuel pressure 15-20 psi
Turn air valve to Start position
Hold ignited burner lighter under burner tip
If burner does not ignite immediately or if flame goes out, close fuel valve, wait until gas is exhausted from
the flues, then re-light
Adjust fuel valve until stack smoke is slightly dark
For full flame, open air and fuel valves alternately and slowly, keeping exhaust slightly dark
Always close fuel valve first when shutting down
After shutting down burners, close stack covers to prevent heat loss
