2.4 CORRELATION BETWEEN GAS PRESSURE AND BURNER OUTPUT
To obtain the maximum output, a gas head pressure of 6.9 mbar is measured with the combustion chamber at
0 mbar using gas G20 with a net heat value of 10 kWh/Nm
3
(8,570 kcal/Nm
3
).
3. INSTALLATION
THE BURNER MUST BE INSTALLED IN CONFORMITY WITH LEGISLATION AND LOCAL STANDARDS.

Gas pressure in the
combustion head – mbar
Boiler door must have a max. thickness of 100 mm,
refractory lining included.
If thickness is greater (max. 260 mm), a combustion
head extension must be fitted, which is supplied
separately.
IMPORTANT
■
Separate the combustion-head assembly
from the burner body by removing nut (1) and
removing group (A).
■
Fix the head assembly group (B) to the boiler
(2) insert the supplied insulating gasket (3).
