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.
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
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.

System inspection and maintenance
13.1
General information
Offer your customer a maintenance contract covering annual inspection
and servicing work as required. To find out what a contract for annual
inspection and demand-based servicing covers, refer to Chapter 13.7,
page 36.
Cleaning and maintenance:
If heating oil is being used, cleaning and maintenance must be carried
out twice a year. Depending on demand/run time, a shorter cleaning
interval may be necessary.
13.2
Why is regular maintenance important?
You should have your customer's system serviced for the following
reasons:
• to achieve a high level of efficiency and to operate the system
economically (low fuel consumption),
• to achieve a high level of operational reliability,
• to maintain a clean and environmentally-friendly combustion.
13.3
Cleaning the boiler with cleaning brushes
▶ Put the main power switch (
Fig. 59, [1]) on the control panel in
position “0”.
▶ Isolate the fuel supply to the burner.
▶ De-energize the system.
Fig. 59 Example showing Logamatic 4311
▶ Slightly lift the front panel and remove by pulling forwards (Fig. 60).
▶ Undo the four machine screws that fasten the burner door to the
front section (
Chapter NOT DEFINED, page 20).
Fig. 60 Removing the front panel
▶ Swing out burner door.
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.
Switch off the system via the boiler room circuit breaker
or heating system emergency shutoff switch only in
emergencies.
DANGER:
Risk of fatal injury from the explosion of
flammable gases.
▶ Work on gas components must be carried out by
trained and certified personnel only.
Spare parts can be ordered from the Buderus spare
parts catalog.
DANGER:
due to electricity.
▶ Before starting electrical work, isolate all poles of the
system and secure against unintentional
reconnection.
