All the burners are factory tested and adjusted. The air flap and combustion head are set to have the CO2 % within the above limit .5 .4Combustion adjustmentThe burners leave the factory set according to the paragraph 5.3 Factory pre-setting.The installation of the burner on the boiler, the commissioning and servicing must be carried out following the boiler technical manual, including the check of the CO2 and CO level in the flue gases, their temperatures and the average temperature of the water in the boiler. In case of outside temperature conditions influencing the combustion it is recommended to adjust the CO2 according to the diagram below.In the cold of winter aim for1% rise in CO 2as the lowerCO 2%.
