Maintenance; Cleaning; Water Hardness; Inspection And Maintenance - Viessmann VITOPEND 100-W Operating Instructions Manual

Cleaning

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

Water hardness

For areas with a water hardness
> 450 milligrams per litre we recom-
mend the use of a water softening sys-
tem.

Inspection and maintenance

Regular maintenance ensures trouble-
free, energy efficient, environmentally
responsible and safe heating. We rec-
ommend you have your heating system
serviced by an authorised contractor at
least every 2 years. For this, it is best to
arrange an inspection and maintenance
contract with your local heating contrac-
tor.

Device

Increased contamination raises the flue
gas temperature and thereby increases
energy losses. We recommend the
appliance be cleaned annually.
Consult your heating contractor.
