5.05 Check and gas pressure regulation
Gas Valve “HONEYWELL V4600C”
The regulation of gas pressure at the pilot burner has to be done at sight , without instrument but
checking the flame envelope completely the thermocouple (fig. 10) without burning excessive gas.
To adjust the pilot flame operate on the screw 2 (fig. 7a).
To adjust the pressure at main burner, operate on the screw 7 (fig. 7a). Rotate clockwise to increase
gas flow and pressure, anticlockwise to decrease gas flow and pressure.
To convert from N.G. to L.P.G. replace the pilot and main nozzles, tighten completely the screw 7
(fig. 7a) and adjust the gas flow-pressure.
N.B.Complete conversion kits for various gas are supplied separately (on request).
5.06 Check and gas pressure regulation
Gas Valve “SIT 820 NOVA”
The regulation of gas pressure at the pilot burner has to be done at sight , without instrument but
checking the flame envelope completely the thermocouple (fig. 10) without burning excessive gas.
To adjust the pilot flame operate on the screw 3 (fig. 7b).
To adjust the pressure at main burner,operate on the screw 2 (fig. 7b). Rotate clockwise to increase
gas flow and pressure, anticlockwise to decrease gas flow and pressure.
To convert from N.G. to L.P.G.replace the pilot and main nozzles, tighten completely the screw 2
(fig. 7a) and adjust the gas flow-pressure.
N.B. Complete conversion kits for various gas are supplied separately (on request).
5.07 Replacing the main and pilot nozzles
To replace the main and pilot burner nozzles, proceed as follows:
Turn off the gas and electricity supply upstream of the boiler.
Remove the whole gas assembly from the combustion chamber (see paragraph 6.03).
Remove the pilot burner (fig. 8)
Remove the main burners from the manifold.
Replace the main and pilot nozzles. Check that the main nozzles gaskets are not damaged. If so
replace them.
Reassemble carefully.
If necessary, calibrate gas pressure at the nozzles as described above.
Check correct operation and that there are no gas leaks.
