• Activate the Heating and Domestic Hot Water functions.
• Run the appliance for at least 15 minutes, with a heating
temperature set to greater than or equal to 50°C (not
applicable for an installation with underfloor heating).
• Vent air from each radiator again until the water flows
normally, then close the vents.
• If you have difficulties in removing the air, launch the air-
removal programs in the heating circuit (see the chapter
("Technical settings for the appliance and list of parameters").
• Make sure that the pressure indicator shows a value of 0.8
bars; otherwise, fill the appliance again.
11.5 Initial lighting
11.5.1 Control
i IMPORTANT:
The combustion for this appliance has been checked,
adjusted and preset at the factory for operation on natural
gas (G20) as defined on the appliance data label.
No measurement of the combustion is necessary.Should
the appliance require to be converted to LPG gas ensure
you follow the gas conversion section before lighting the
boiler.
• Check that the appliance has been installed in accordance with
the instructions.
• Check the integrity of the flue system and flue seals.
• Check the integrity of the appliance combustion circuit and
relevant seals.
• Check that all internal/external controls are calling for heat.
• Check that the gas service isolation is open.
• To adapt the appliance to another type of gas, see chapter
"LPG conversion".
11.5.2 Adjusting the temperature
• Light the appliance by following the procedure below.
• Select the "Heating + domestic hot water" function by pressing
the “Mode” button repeatedly to scroll through your options
until are shown.
The appliance will enter a self checking routine, then the fan
will start and the ignition sequence commence. The boiler, if
necessary, will automatically repeat the ignition sequence a
further 4 times.
If the burner fails to ignite “F28” will be displayed, initially, this
may be due to air in the gas supply line. Press the reset button.
Do not use the reset button to purge the installation - never press
reset more than 3 times.
• Select the heating function only by pressing the "mode"
button repeatedly ( is shown only).
• Press or buttons to adjust.
• Select the hot water function only by pressing the "mode"
button repeatedly ( is shown only).
• Press or buttons to adjust.
• Check that hot water is available at all taps, then close.
• Return the appliance to the correct mode by pressing "mode"
button unit the desired functions are activated.
11.6 Gas rates
The supply from the governed meter must be of adequate size to
provide a steady inlet working pressure of 20mbar (8in wg) at the
boiler.
• On completion, test the gas installation for tightness using the
pressure drop method and suitable leak detection fluid, purge
in accordance with the above standard.
i IMPORTANT:
Due to the modulating operation of the boiler and the
need to check the gas inlet pressure and measure the
gas rate at maximum rate, it will be necessary to force it
to maximum.
• Activate the test mode "P.01" and set the value to HI in order to
force the burner at P. max. See chapter "Specific adjustment >
Appliance technical settings and parameter list > Test modes".
11.6.1 Operational Gas Inlet Pressure

2
Key
1 Gas service isolation valve
2 Test point
• With all other gas appliances operating, check the operational
supply pressure at the gas service isolation valve test point.
The nominal supply pressure for Natural Gas (G20) is 20mbar.
The nominal supply pressure for LPG (G31) is 37mbar.
• Turn the taps and appliances off, then disconnect the pressure
gauge.
Additionally the safe nominal maximum heat input of the
appliance can be achieved at an inlet pressure down to 15mbar.
i IMPORTANT:
The burner pressure cannot be measured and is not used
to measure the gas rate.
