1.3 Ignition and shut-down

Ignition
• Open the gas cock of the boiler.
• Purge the gas supply of any air upstream of the gas valve.
• Turn on the main switched spur to the boiler.
• Press the boiler switch to on.
• Rotate the C.H. temperature adjustment knob above Min position.
• At this point, the burner ignites and the boiler starts to function automatically, operated by its control
and safety devices.
If after completing the start-up procedure correctly, the burner fails to ignite and the boiler shut
down warning lights up, wait about 15 seconds then press the reset switch. The reset electronic
control unit will repeat the start-up cycle. If after a second attempt the burners still fails to ignite,
consult the paragraph "Troubleshooting".
If there is a power failure while the boiler is in operation, the burners automatically go out and
re-ignite when the power returns.
If the system is filled with very cold water, the boiler will automatically light due to the frost ther-
mostat sensing the low temperature. The boiler will not shut down, until the water temperature
reaches 10°C.
Shut-down
Close the gas isolation valve , push the button "A" to OFF and disconnect the appliance from the mains
power supply.
When the boiler power is off the boiler anti-freeze protection is not active.
For extended periods of inactivity during the winter months, and in order to avoid damage due to
freezing, all the water should be drained from the boiler; alternatively, place approved antifreeze
fluid in the central heating system.

1.4 Settings

Setting the ambient temperature (using the optional room thermostat)
Set, using the room thermostat, the temperature required inside the rooms. Based on the demand from
the room thermostat, the boiler is ignited and heats the system water to the set central heating outlet
temperature. When the required temperature inside the rooms is reached, the boiler switches off. A
room thermostat must be used as per the building regulations 'Part L' this will maintain the system at
the set central heating outlet temperature and ensure maximum efficiency.
System water pressure control
Using the filling loop and with the system cold top up the water pressure to approximately 1bar. Once
the operation is completed, always close the filling loop. This device is fitted to the system by the installer
on the central heating return pipework.

1.5 Maintenance

It is recommended to have annual service of the appliance performed by qualified personnel. Please
refer to Chap. 3.3 in this manual for further information.
The casing, the control panel and the aesthetic parts of the boiler can be cleaned using a soft and damp
cloth, dipped in soapy water if necessary. Do not use abrasive detergents or solvents.
