Inspection and Maintenance

Cleaning
All equipment can be cleaned with a commercially
available domestic cleaning agent (non-scouring).
Clean the surface of the programming unit with the
microfibre cloth provided.
Inspection and maintenance
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, it is best to
arrange an inspection and maintenance contract with
your local heating contractor.
Appliance (boiler)
Increased contamination raises the flue gas temperature
and thereby increases energy losses. We recommend the
appliance is cleaned annually.
DHW tank (if installed)
Maintenance and cleaning should be carried out no
later than 2 years after commissioning and as required
thereafter.
Only a qualified heating contractor should clean the
inside of a DHW tank and the DHW connections.
If any water treatment equipment (e.g. a sluice or
injection system) is installed in the cold water supply
of the DHW tank, ensure this is refilled in good time.
In this connection, observe the manufacturer's
instructions.
In addition for Vitocell 100:
We recommend that the correct function of the sacrificial
anode is checked annually by your heating contractor.
The function of the sacrificial anode can be checked
without interrupting the system operation. The heating
contractor will check the ground current with an anode
tester.

Service Schedule

Safety valve (DHW tank)
The function of the safety valve must be checked every
six months by the user or a contractor through venting
(see valve manufacturer's instructions). The valve seat
may become contaminated.
Water may drip from the safety valve during a heat-up
process. The outlet is open to the atmosphere and must
not be closed off.

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 cables / lines
If there is damage to the connecting cables or lines of the
appliance or externally installed accessories, these must
be replaced with special cables or lines.
Only use Viessmann cables / lines as replacement.
For this, notify your qualified contractor.

and environmentally friendly operation.
The service schedule can be found in the installation and
service instructions.
