Burner adjustments

The suggested adjustments for the operation of the combinable burner installed at sea level are shown in the table.
Description
ESTELLE HE B4 INOX ErP
Values obtained during operation
(**)
When the burner is installed at altitudes up to maximum 1300 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) (as per the regulations in force)
- Bacharach index (≤ 0,5)
- Flue gas temperature.
