Danger!

Risk of injury and material damage due

to incorrect maintenance and repairs.

If maintenance is not carried out, or carried

out incorrectly, this may adversely affect

the operational reliability of your boiler.

> Never attempt to perform maintenance

work or repairs on your water boiler by

yourself.

> Always employ a recognised heating

engineer.

9.1 Servicing the boiler

Permanent operational readiness and safety, reliability and

a long working life require inspections and maintenance

work to be carried out annually on the boiler by your

approved competent person.

Regular servicing ensures maximum efficiency and econom-

ical operation of your boiler.

We recommend making a maintenance agreement.

9.2 Caring for your boiler

Caution!

Unsuitable cleaning agents can cause

damage!

Unsuitable cleaning agents (scouring or

other cleaning agents) can damage the

exterior, the fittings or the controls.

> Do not use sprays, solvents or cleaning

agents containing chlorine.

> Clean the exterior of your boiler with a damp cloth and a

little solvent-free soap. Do not use any detergent.
