Mounting Regulations
Sequence of functions
After the unit has been switched on or in case heating is reqired (auto-matic function with room thermos-tat), the supply air fan also switched on. After the preliminary ventilation of the burner, the solenoid valve opens the fuel supply for the oil nozzle.
The fuel, sprayed under high pres-sure, is enriched with an amount of oxygen that has been adapted to the heating capacity and ignited using an electrical, high-voltage ignition spark.As soon as a flame is burning wit-hout a problem, the automatic bur-ner relay assume the optical flame monitoring function.After a short period of time, hot air is blown out.
The automatic burner relay perform all device functions fully automati-cally and monitor them securely.
In case of any irregularities or an instable or extinguished flame, the unit is deactivated by the automatic burner relay. The pilot lamp on the automatic burner relay lights red.
A restart of the unit is only possible after a manual reset of the auto-matic burner relay.
After the unit has been shut down using the operating switch or by the room thermostat, the supply air fan continues to run for a certain period of time to cool the combus-tion chamber and then shuts down independently.
Concerning to each room tempe-rature the thermostat operation repeats the descripted operation automatically.
When the unit is in use, the safety guidelines of the employers‘ liability insurance associations, the respective country construction ordinances, and the burning appliance regulations basically apply.For example for Germany:
