Maintenance

6.1

General notes

Important for energy saving!

z

Please ensure your boiler and burner is checked
and maintained annually by a heating engineer.
We recommend that you take a Service contract
to ensure this is done regularly. Failure to
maintain the boiler will lead to higher fuel cost,
possible breakdown reduced service life.

z

You can obtain special cleaning brushes from
your local Buderus dealer.

6.2

Cleaning with cleaning brushes

z

Disconnect your heating system from the mains
electricity supply.

z

Switch the On/Off switch (Fig. 49,

Item 1

) on the

control unit to "0" (OFF).

z

Isolate the main fuel valve.

z

Slightly raise the front wall and remove forward
(Fig. 50).

z

Loosen the four screws securing the burner door on
the front sections (see chapter "2.6.3 Burner door
installation", page 20).

z

Open the burner door.

NOTE!

e.g. activate the emergency stop switch for
your heating system outside your boiler
room and secure against unintentional
switching on.

ATTENTION!
Work on fuel lines MUST only be
perfomed by

registered engineers [In

the UK engineers must be CORGI or
OFTEC registered]
