3.15 Eolo 27 Maior @ variable heating power.
N.W.: Pressure values specified in the table indicate
the difference of pressure values between the gas
valve outlet and the combustion chamber. Adjust-
ments 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 the sealed chamber posi-
tive pressure test outlet . Power data specified in the
table refer to a 0,5 metre intake/exhaust pipe. Gas
flow rates refer to heat power below temperature of
15°C and at a pressure of 1013 mbar. Burner pres-
sure values refer to use of gas at 15°C.
