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
the sealed chamber positive 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 pressure values refer to use of gas at
15°C.
Flue temperature values refer to air inlet temperatures of 15°C.
