step

Using the filter module VMF, the gas flow upstream of the 

gas valve VAS and the air/gas ratio control VAG is cleaned. 

The gas/air mixture is set using the fine-adjusting valve VMV. 

A constant mixture setting is maintained over a wide control 

range while at the same time preventing air deficiency. This 

type of control is used on boilers with multi-stage or infinitely 

adjustable forced draught burners.
