219A
   
HEATER & THERMOSTAT
5 to 25  Gallons -   300 watts, 120 vac
This assembly is used to heat the fuel oil inside a 5-25 gallon
tank and maintain a specified temperature.

While the thermostat controls the on/off of the actual heater to
achieve desired fuel temperature, a float switch and relay
monitors fuel level .  If the fuel drops past a pre-set level, the
heater is shut off regardless of the temperature.  This is to
protect the heater from "burn-out".
