Shutting down the heating system

Logano G225/Logano plus GB225 - We reserve the right to make any changes due to technical modifications.

Shutting down the heating system

8.1

Normal shutdown

Switch the ON/OFF switch on the control unit OFF
(position "0"). This switches off the boiler and all its
components (such as the burner).

Turn off the fuel supply at the main shut-off valve.

Shutting down the heating system in emergencies

8.2.1

What to do in an emergency

Explain to the customer what to do in an emergency, e.g.
a fire.

Never put yourself at risk of fatal injury. Your own safety
is paramount.

Close the mains gas shut-off valve.

Isolate the heating system from the mains power
supply by means of the heating system emergency
stop switch or the appropriate electrical fuse/circuit
breaker.

Caution: Risk of system damage due to
frost.
The heating system can freeze up, if it has
been shut down.

Leave the heating system permanently
switched on as much as possible.

Protect the heating system against frost
by draining the heating system and DHW
pipes from the lowest point.

6 720 615 876-71.1RS

Only use the boiler room circuit breaker or
heating system emergency stop switch to
switch off the heating system in an
emergency.
