GAS TRAIN DESCRIPTION FOR GAS PRESSURE ADJUSTMENT
The burners are combined with monobloc pneumatic proportional
gas valves that allow the quantity of gas supplied and therefore
the power output, to be adjusted.
A pressure signal, detected in the air circuit, is sent to the
pneumatic gas valve, which delivers a quantity of gas proportional
to the airflow processed by the fan.
In order optimise the overall dimensions, the gas train is mounted
directly on the body of the burner.
