Set P2 as you need.
• To reset the value of slow ignition you need to turn off the boiler, to again act on the parameters and to
remake ignitionr verifying the attainment value of desired pressure.
ATTENTION: the slow ignition time for its adjustment is 5 seconds after which the nozzle pressure will
increase or decrease according to the energetical need. If a further change is needed repeate this operation
by turning the boiler on and off.
2.9.2 NOMINAL HEAT ADJUSTMENT
The greatest heating power has to be adjusted according to system needs.
Gas pressure values are shown at pages 23,24 in the table “INJECTORS PRESSURE TABLE”.
For the adjustment of the burner gas pressure follow these indications:
• Set the boiler on “Winter” position;
• create a jumper on the ambient thermostat in order to start the boiler;
• push for 9 sec P1 and P2 and see c) “Mode of parameters setting” (look at page 20)
Set P1 as you need.
N.B.: wait about 10 seconds to allow the pressure stabilisation after the slow ignition.
2.10 DIFFERENT GASES
This is a LPG or natural gas boiler as well. The transformation from one gas type to the other one has to be
carried out as follows:
Transformation from methane to LPG gas
• replace burner injectors
• change the JP1 jumper position and set it to “LPG” position (see the electrical scheme);
• adjust MIN/MAX pressure levels keeping in mind the above shown instructions;
• as far as the injectors diametres and the burner gas pressure are concerned, see the above table;
• after this seal the valve regulator by means of a coat drop.
Transformation from LPG to methane
• replace burner injectors;
• change the JP1 jumper position and set it to “METHANE” position (see the electrical scheme);
• adjust MIN/MAX pressure levels keeping in mind the above shown instructions;
• as far as the injector diametres and the burner gas pressure are concerned, see the above table;
• after this seal the valve regulator by means of a coat drop.
