Upkeep; Cleaning; Inspection And Maintenance; Boiler - Viessmann VITODENS 050-W Operating Instructions Manual

Cleaning

The appliance may be cleaned with a
commercially available domestic clean-
ing agent (non-scouring).

Inspection and maintenance

The inspection and maintenance of a
heating system is prescribed by the
Energy Saving Ordinance [EnEV - Ger-
many] and the DIN 4755,
DVGW-TRGI 2008 and DIN 1988-8
standards.

Boiler

Increasing boiler contamination raises
the flue gas temperature and thereby
increases energy losses. All boilers
should therefore be cleaned annually.

Power cable

Never replace faulty power cables. Have
a qualified electrician replace faulty
cables.
Regular maintenance ensures trouble-
free, energy efficient and environmen-
tally responsible heating. For this, we
strongly advise you to arrange an
inspection and maintenance contract
with an authorised heating contractor.
