Installation
Example with natural gas G20:
Operation at maximum modulating output
Gas pressure at an output of 6000 kW
= 27.8 mbar
Pressure in combustion chamber
=
5 mbar
27.8 + 5
= 32.8 mbar
pressure required at test point P1)(Fig. 31).
Key (Fig. 31)
P1 Pressure test point at the combustion head
P2 Pressure test point at the gas butterfly valve
2 Manual on/off valve
12 Pilot gas supply
13 Pressure adjuster of pilot line
14 Safety valve
15 Operation valve
5.13.5 Pilot - gas train connection
The burner is fitted with a dedicated gas train that is fixed to the
pipe coupling.
It should be connected to the main train downstream the fil-
ter or the pressure adjuster (depending on configuration).
Oil burners (with LPG pilot) can be directly connected to the LPG
cylinder.
5.13.6 Ignition pilot burner
For proper operation, adjust gas pressure (measured at pressure
test point 1)(Fig. 32) as follows: 16 mbar (7.3 Nm
3
/h).
In the case of ignition problems check:
correct positioning of the ignition electrode;
the gas pressure, according to indications.

WARNING
Supply pressure 68 ÷ 500 mbar.
WARNING
Check pilot flame stability before starting up the
main burner.
