Vitotronic 200 and 300-K Operating

Maintenance

Cleaning
All equipment can be cleaned with a commercially
available domestic cleaning agent (non-scouring).
You can clean the front of the programming unit with
a microfibre cloth.
Inspection and maintenance
Inspection and maintenance of your heating system is
prescribed by the Energy Savings Order.
Regular maintenance ensures trouble free, energy
efficient, environmentally responsible and safe heating.
Your heating system must be serviced by an authorized
contractor at least every 2 years. For this, we advise you
to arrange an inspection and maintenance contract with
your local heating contractor.
Boiler
Increasing boiler contamination raises the flue gas
temperature and thereby increases energy losses.
For that reason, all boilers should be cleaned annually.
DHW tank (if installed)
Maintenance and cleaning should be carried out no later
than two years after commissioning and thereafter as
required.
Only a qualified heating contractor should clean the
inside of a DHW tank and the DHW connections.
Refill any water treatment equipment (e.g. a lock
or injection system) in good time, if such equipment
is installed in the cold water supply of the DHW tank.
Observe the manufacturer's instructions.
Additionally for a Vitocell 100:
We recommend that the correct function of the sacrificial
anode is checked annually by your heating contractor.
The anode function can be checked without interrupting
the system operation.
The heating contractor will check the ground current
with an anode tester.
Safety valve (DHW tank)
The safety valve function should be checked every six
months by venting, either by the system user or the
local heating contractor. The valve seat may become
contaminated (see the valve manufacturer's instructions).
Potable water filter (if installed)
To maintain high hygienic standards, proceed as follows:
H Replace filter element on non-back flushing filters every
six months (visual inspection every two months).
H On back flushing filters, back flush every two months.
Damaged connecting cables
If connecting cables of the appliance or externally installed
electrical accessories are damaged, replace them with
special connecting cables. Replace only with Viessmann
cables. Contact your local heating contractor.
