VIESSMANN Training Videos Vitodens 200 Annual Burner Maintenance v2 

I've only replaced two seals in 16 years and I only work on Viessmann. The seals are fantastic

Its a pity there is no information about a graphite gasket under the burner, about if we could blow an air into ventury to clean it, no info of a vent maintanance, elektrodes. I just don't understand why there is a warning as if video was for a professional.

My 6 month old veissmann fan died. Not happy.

Where can we get this service kit?

Can you please GAP An ionization rod. In real life, they don't seem to bend.

Absolutely garbage unit just like their bmw and mercedes cars ,I am installing navian for 14 years and never ever had to touch the burners ,works like a charm
