The scope of delivery includes:

– Infrared oil heater with transport wheels
- Operating manual

Mode of operation

The device is a radiation heater with an oil burner.

The fuel is taken by the oil pump from the tank, compressed to operating pressure and fed to the nozzle. The nozzle injects the fuel as a mist into the combustion chamber where it ignites. The result is a flame which, together with its combustion gases, heats the combustion chamber and the heating plate.

The exhaust gases are fed out of the device.

The heating plate provides uniform radiation heat.

The heating output (two levels) of the device is controlled with the device switch.

The heating plate is protected by a guard and a safety hoop to prevent direct contact.

The exhaust gases are discharged through the heating plate.

Operation with room thermostat

The device can be run in conjunction with a room thermostat so that it is operated on the basis of the actual room temperature.
