Combustion adjustment

In conformity with EN 267, the installation of the burner on the
boiler, the adjustment and testing must be carried out in compli-

the CO and CO2 concentration in the flue gases, their tempera-
ture and the average temperature of the water in the boiler.
The temperature of the combustion air (relative to
the place where the burner is installed) may vary
during the season, it influences the CO
burner. We recommend adjusting the CO
