The antifreeze system does not work when the power and/or gas to the unit are turned off. To avoid damage
caused by freezing during long idle periods in winter, it is advisable to drain all water from the boiler, DHW
circuit and system; or drain just the DHW circuit and add a suitable antifreeze to the heating system, complying
with that prescribed in sec. 2.3.
Boiler lighting
Switch on the power to the unit.
