Cleaning the heating surfaces

Please note

There should be no scratches or

other damage on the heat

exchanger surface that comes

into contact with hot gases. This

could lead to corrosion damage.

Never use brushes to clean the

heating surfaces.

Brushing can cause existing

deposits to get stuck in the coil

gaps.

Note

Discolouration of the heat exchanger

surface is a normal sign of usage. It has

no impact on the function and service life

of the heat exchanger.

The use of chemical cleaning agents is

not necessary.

1. Use a vacuum cleaner to remove

deposits from heating surfaces

the heat exchanger.

2. If required, rinse heating surfaces

with water.

3. Check condensate drain and clean

siphon. See the following chapter.
