12 Shutting down the system
You can connect control panels of the 4000 series to the Logano G515.
The shutting down process for the different types of control panel is the
same.
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.
▶ Shut off the fuel supply to the burner.
12.2 Shutting down the system in an emergency
In other dangerous situations, immediately close the main fuel shut-off
valve.
▶ Shut off the fuel supply to the burner.
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 from the heating system at its lowest
point using the drain valve. To do this, open the air
vent at the highest point in the system.
In an emergency disconnect electrical power to the
boiler and heating system by shutting off the emergency
shut-off switch on the boiler or outside the boiler room,
or disengage the heating system circuit breaker.
