SHUTTING DOWN THE BOILER
To switch off the boiler, place your finger on the power touch button
(27)
for 1 second. In Off mode,
while the boiler is plugged into the mains and connected to the fuel installation, its heating and DHW
functions will be switched off but the anti-frost protection and pump anti-block functions will remain
activated.
To shut down the boiler functioning completely, unplug it from the mains and cut off the fuel supply.

DRAINING THE BOILER
The water is drained from the boiler by opening the air drain valve
(23)
inside the boiler (on the lower
right hand side on opening the door). Connect a flexible tube to this valve and run it to a drain. After
draining the boiler, close the valve again and remove the flexible tube.

DRAINING THE SOLAR CIRCUIT
If you need to drain the solar circuit, connect a hose to the solar hot water tank drain valve
(5)
and run
the hose to a suitable container (minimum capacity 19 litres), so that the heat-carrying fluid can be
reused if necessary. Open the drain valve and the level valve. After draining the circuit, close the shut-
off valves and disconnect the hoses.
