TECHNICAL DATA
BURNER DESCRIPTION
BURNER EQUIPMENT
ACCESSORY
RADIO DISTURBANCE PROTECTION KIT: code 3010386
If the burner is installed in places particularly subject to radio disturbance (emission of signals exceeding
10 V/m) owing to the presence of an INVERTER, or in applications where the length of the thermostat
connections exceeds 20 metres, a protection kit is available as an interface between the control box and
the burner.

WORKING RANGE
COMBUSTION CHAMBER PRESSURE - MAXIMUM OUTPUT
(in compliance with DIN 4788)
MINIMUM GAS PRESSURE - OUTPUT
Pressure: detected at the pressure test-point 8) (fig. 1) with nil mbar into the combustion chamber.
Should the combustion chamber be pressurized, the pressure necessary will be that of the
graph plus the pressurization value.
Example: to obtain 550 kW it is necessary a gas pressure of 9 mbar and the combustion head set as
indicated at page 7.
If the combustion chamber is pressurized at 2 mbar, the pressure detected at the test-point
8) is: 9 + 2 = 11 mbar.
If this value is too high, for very low gas pipework pressures, the gas gear 6) (page 7) could
be more open.
Do not decrease the pressure at the coupling under the values shown in the diagram.
Output: the maximum value is obtainable with gas Pci 8600 kcal/m
