General information 1. General information An oil-fired system must be installed in compliance with a number of regulations and requirements. It is therefore the duty of the installer to be familiar with all applicable regulations and requirements. Installation, start-up and maintenance must be performed with utmost care. The burner must not be operated in rooms with high levels of air humidity (laundry rooms), dust or corrosive vapours.
Install flange and burner 9.Install flange and burner Attach the burner flange and the seal to the heat generator. 10. Connect to power supply 7-pin • Connect the burner to the power supply using the supplied connector unit as indicated in the wiring diagram.
Oil pump 12. Oil pump The oil pumps serve as delivery units, pumping oil into the burner tank. The atomisation of the oil is not dependent on the oil pressure. Suntec oil pump: = feed = return = pressure pipe connection = pressure measuring connection = vacuum measuring connection = pressure adjustment...
Function testing the control unit 15. Function testing the control unit Carry out the following checks after start-up and after the burner has been serviced: • Restarting with a covered flame detector: the control unit must go into fault mode on expiration of the safety period. •...
If the oil level is too high, the float switch will switch off the burner. If the oil level is too low, the heating cartridge will become encrusted or damaged. Adjustment table for rapeseed oil Burner type G100 Output in kW Oil throughput in kg/h 10.1...
Settings for primary airflow 17. Settings for primary airflow The primary airflow should be set using the pressure regulator (1) according to the required burner output. The information given in the diagram can be used as guide values. Higher-viscosity fuels require higher air pressures. 18.
Flue connection 19. Flue connection The prerequisite for perfect operation of the furnace is a correctly dimensioned flue. Dimensioning is effected in accordance with DIN 4705 in consideration of DIN 18160 and based on the boiler and burner outputs. For operation on a sliding basis, provide flues as per DIN 18160 part, group 1. The flue gas mass flow of the total rated heat output must be factored into the calculation.
