3.6. Adapting to other gases and regulating the burner
This boiler is built to run on the type of gas specified on the order, which is shown on the packaging and on the boiler rating plate.
If you wish to switch to another type of gas, this must be done by a qualified technician using the accessories supplied by the manufacturer.
He will make the necessary modifications and adjustments to ensure efficient operation of the boiler.
3.6.1. Switching from METHANE to PROPANE
• Open the boiler front panel, as described in par. 3.2.7.1.
• unscrew the outlet connection to the gas valve (A in fig. 24);
• replace the diaphragm in the relevant seating, with the one for PROPANE (see tables 3 and 4).
• re-connect the outlet connection to the gas valve (A in fig. 24);
• see par. 3.6.3.
3.6.2. Switching from PROPANE to METHANE
• Open the boiler front panel, as described in par. 3.2.7.1.
• unscrew the outlet connection to the gas valve (A in fig. 24);
• replace the diaphragm in the relevant seating, with the one for METHANE (see tables 3 and 4).
• re-connect the outlet connection to the gas valve (A in fig. 24);
• see par. 3.6.3.
3.6.3. Burner adjustment
Maximum heat output adjustment
• set max heat output adjuster (fig. 17) to maximum (turn it fully clockwise); the LCD will display the desired maximum heat output,
in percentage with respect to the boiler available max heat output.
• position selector 2 (fig. 1) to WINTER;
• verify the optional room thermostat (when available) to be set to ON;
• start “chimney sweep” boiler mode (see subsection 3.2.7.1);
• adjust flue gas CO

value to be within the range stated in table 12;
• allow boiler to keep operating in chimney sweep mode and go to the following point;
Minimum heat output adjustment
• set max heat output adjuster (fig. 17) to MINIMUM (turn it fully counter-clockwise); the LCD will display the desired maximum
heat output, in percentage with respect to the boiler available max heat output.
• adjust flue gas CO
2
by turning offset adjuster C (fig. 25) and verify CO
2
value to be within the range stated in table 12;
• to end the chimney-sweep function, set selector 2 (fig. 1) on a position other than WINTER and then to the desired position.
