3.3 Burner is thermostatically controlled with an adjustable temperature range of 175 degrees to 550 degrees. The vat is equipped with a 0 to 650 degree thermometer with an 18″ stem. Thermostat sensing bulb and thermometer are located together in vat for an accurate temperature control.

3.4 Gas valve used with system is a millivolt powered, 100% safety shut-off valve with block out installed for L.P. gas only. For operation of gas valve, a pilot-generator combination producing 750 millivolts is used. The system includes all necessary piping, connectors, regulators, and valves for operation. All parts are UL approved.

3.5 The buggy is equipped with a manual operated agitator supported at top and bottom of vat.
