8 SPECIAL POSITIONS
8.1 Ignition position
The ignition point is independent from the other curve points of the air/fuel ratio curve.
As far as dual fuel burners, the ignition point set for the gas operation does not depend on the one set for the oil operation. LMV5x allow two different
ignition position for gas mode and oil mode.
The burner is provided with a factory-set ignition point, to make easier the first ignition procedure by the Service Centre.
The air actuator at the ignition point, is factory set at a 6°/7° opening, while the gas actuator is set at 12°/15°. In case of burner provided with VSD, it is
suggested to set ignition at 100% VSD frequency.
