TECHNICAL DATA
(1)
Reference conditions: Ambient temperature 20°C - Barometric pressure 1000 mbar - Altitude 100 m a.s.l.
(2)
Pressure at pressure switch test point 23)(A)p.12 with zero pressure in the combustion chamber and maximum burner output.
(3)
Sound pressure measured in manufacturer’s combustion laboratory, with burner operating on test boiler and at maximum rated output.
ACCESSORIES
(optional)
OUTPUT POWER REGULATOR KIT:
Under modulating operation, the burner automatically adapts to one of an infinite number of firing
rates between the low and high flame output position, thus ensuring stable operating conditions in terms of temperature or pressure. Two compo-
nents should be ordered: • Power regulator to install to the burner; • probe to install to the boiler.
