N.B.: Pressure values specified in the table indicate the difference of
pressure values between the gas valve outlet and the combustion
chamber. Adjustments are therefore carried out with the differential
pressure gauge ( "U" or digital type) with the sensors inserted in the
test pressure outlet of the modulating adjustable gas valve and on
Eolo Star technical specifications.
