Further details regarding the individual steps

Only use plastic brushes, not wire

brushes or sharp objects.

For normal cleaning, flush the heating

surfaces thoroughly with a water jet. You

may use cleaning agents if you notice

stubborn residues, surface discoloura-

tion or soot deposits.

For this, observe the following:

■ Only use solvent-free cleaning agents.

Ensure that no cleaning agent gets

between the boiler body and the ther-

mal insulation.

■ Remove soot deposits with alkaline

cleaning agents with additional surfac-

tants (e.g. Fauch 600).

■ Remove coatings and surface disco-

louration (yellow-brown) with slightly

acidic, chloride-free cleaning agents

based on phosphoric acid (e.g. Antox

75 E).

■ Remove loose deposits from the

boiler; flush the heating surfaces and

the flue gas collector thoroughly with a

water jet.
