Power schemes

As it is evident from the diagram above, in the pre-mixed system air and gas are sucked in

and mixed together by a fan. It is possible control the quantity of the air-gas mix because

the fan rotation speed is electronically controlled, to obtain a variation of gas flow and thus

the power of the burner.

There are 3 different power levels:

•

Full power*: operating at maximum capacity and blower engines at full speed, the

inlet gas circuit is in total decompression and the gas valve adjustment of the valve

does not cause significant differences. The combustion is totally dependent on the

nozzle installed.
