Viessmann Combustion Analysis
So I did my combustion analysis on my personal Viessmann install at my house results are not exactly where I want them.. Spoke to Viessmann and there are no adjustments to be made to the boiler itself..
Model - Vitodens 100-w B1HA
o2 - 7.6-8%
co2 - 8.8-9.1%
co - 50-60ppm
EA - ~55
The system is two pipe vented, I would like to see the co2 about 1-1.5% higher, any suggestions?
Inlet pressure 13in
