3. Adjust combustion
When adjusting, the ratings data given by the boiler manufacturer and the capacity
graph of the burner should be observed [ch.3.4.6].
Check CO content of combustion and if necessary adjust combustion values via
air damper and/or diffuser. Observe mixing pressure while doing so.
Calculate gas throughput (operating volume VB) required [ch.7.6].
Optimise setting pressure until gas throughput (VB) is achieved.
Check combustion values
Determine combustion limit and set excess air via air damper and/or diffuser
[ch.7.5].
Determine gas throughput once more and adjust if necessary.
Re-set excess air.
4. Check start behaviour
Switch off and restart burner.
Check start behaviour and if necessary correct ignition position.
If the ignition position has been altered:
Re-check start behaviour.
