Can any Viessmann experts tell me what a setting does?

Evening all. My Vitodens 100 B1KC manual has a section called 'matching the burner output to the flue length'. The setting applies a numbered 'correction factor' depending on flue length. Uncorrected is for flues up to 2m long, setting 1 is for up to 5m and so on.

My flue is 3m plus a plume kit but the setting is still on zero. The installer didn't seem to know much about viessman so I doubt the setting is deliberate. Can anyone tell me what the setting actually does? Speeds up the fan? changes the delay between fan starting and firing? Something else?

Congratulations at being the first person in history to decipher some useful information out of a Viessmann instruction manual.
If in doubt, phone the customer helpline, they will hopefully be able to point you in the right direction.

I personally think they're dog poo, but you might get some info out of the ladies in the office

Probably wrong information.

Last time time it nearly cost me £250 in the wrong parts. Even Hugh got it wrong the first time.

Crap boilers too
