The burner provides the flame to heat the oil. It is activated by the burner switch, which when in
the "on" position, completes the limit circuit. When all limits are in the "closed" or operating
position, the flame program control will activate for automatic firing sequence.
i.
An ultraviolet (UV) scanner monitors the flame at all times during the firing cycle. If a loss of flame
occurs, fuel valves will close within 2 to 4 seconds and flame program control will go into alarm
condition. Reset must be pushed to reactivate control.
j.
General. The hot oil heater operates in conjunction with several other units to accomplish its
purpose, which is to supply heat for the heating of liquids. It requires an external power source
and external fuel supply. Using the liquid transfer hoses, a closed circulating system must be set
up between the hot oil heater and the external system requiring heat to carry the heated transfer
oil to the external system and return it to the hot oil heater for reheating. The hot oil heater should
be installed and operated on a level site and with adequate ventilation.

Description
The Volcanic Model 200STM77 Hot Oil Heater (Fig. 1 & 2) is a mobile, heavy duty, high output heater, consisting
of the heater unit complete and mounted on a trailer. It normally is used with two asphalt meters operating in
parallel or with a heavy duty asphalt plant, and is designed to heat transfer oil and pump this oil to the external
systems requiring heat. External electrical power and fuel must be provided for its operation. Power supply
should be 15 Kilowatt, 3 Phase, 60 Hertz, 230 Volts capacity.
