Shutting down the system

You can connect control panels of the 4000 series to the Logano G315.
The shutting down process for the different types of control panel is the
same.
NOTICE: Risk of system damage from freezing.
▶ The heating system can freeze up if it is disabled, e.g.
shut down due to a fault.
▶ Protect the heating system from freezing when
temperatures below freezing are expected. Drain the
boiler water out of the heating system at its lowest
point using the drain valve. To do this, open the
purger at the highest point in the system.
12.1 Shutting down the heating system via the control
panel
Shut down your boiler via the control panel. Shutting down the control
panel automatically also switches off the burner.
▶ Isolate the fuel supply to the burner.
12.2

Shutting down the system in an emergency

Switch off the system via the boiler room circuit breaker
or heating system emergency shutoff switch only in
emergencies.
In other dangerous situations, immediately close the main fuel shut-off
valve and the power supply of the heating system via the boiler room
main circuit breaker or the heating system emergency shutoff switch.
▶ Shut the fuel supply to the burner.
