11 Glossary
11.1 Start fuel flow rate
The start fuel flow rate is the quantity of fuel ignited by the
ignition device on start-up of the burner.
11.2 Positions
Position is the angle (0 – 90° or 0 – 100%) which the actuator
approaches. There are 4 positions, depending on the set
operating mode:
Closed = 0° = 0%,
Low = low-fire rate,
Middle = intermediate,
High = open.
11.3 Adjustment angle for the “open” position
The adjustment angle for the “open” position indicates the
approached position of the actuator and thus determines the
maximum quantity in intermittent mode.
