The pump pressure stabilises after roughly 5 minutes of operation.
(**)
Diesel flow rate value referred to a lower heating value (Hi) of 12,01 kWh/kg.
When the thermal unit is installed at altitudes up to maximum 1,300 m.a.s.l., due to the lower air density, the factory adjustments for
the burner must be modified as follows:
– keep the nozzle mounted in the factory
– do not vary the position of the combustion head
– gradually reduce the pump pressure to reduce the fuel flow rate
– adjust the air shutter by taking the following readings:
- CO
2
(%)
- CO (ppm)
- NOx (ppm)
- Bacharach index
- flue gas temperature.

WARNING
All operations must be carried out exclusively by the Sime Technical Support Service or by professionally qualified personnel,
according to the instructions appearing in this manual under the paragraph
