1.3 Ignition and shut-down
Ignition
• Open the gas isolation valve upstream of the boiler.
• Ensure 230V supply is present at the boiler.
• Place the main switch “A” in the ON position.
• Place knob “B” in the Winter position and set the room thermostat, if fitted, to the required
temperature value. At this point, the burner will ignite and the boiler will start operating automatically,
managed by its control and safety devices.
If, after having correctly performed the ignition operations, the burners do not ignite and the
lock-out warning light is on, wait around 15 seconds, then turn knob A to the RESET position
and release it. The control unit will be reset and will repeat the ignition cycle. If, after a number
of attempts, the burners does not ignite, refer to the paragraph on troubleshooting.
Shut-down
Close the gas isolation valve upstream of the boiler, turn knob “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, both the domestic hot water and
the central heating system; alternatively, drain only the domestic hot water and place approved
antifreeze fluid in the central heating system.
