water, the sum of alkaline

earths of which must not

exceed 0.02 mol/m

Observe the "Water quality

requirements" on page 22.

Note

Record the fill volume and water

hardness on page 13.

5. Check the system pressure.

6. Check the fuel oil level or the gas

supply pressure.

7. Openthefluegasdamper(if

installed).

8. Check that the cleaning aperture

ontheflueoutletisclosed.

9. Open the gas or oil supply line

as quickly as possible.

12. After the flow temperature has

been reached, switch ON the heat

consumers in sequence and

change the burner over to auto-

matic mode.

13. Check all gaskets/seals and plugs

tion pump will create negative

pressure inside the boiler.

Drain the boiler with a suction

pump only when the air vent

valve has been cracked open.

Opening the boiler door and clean-out cover

Note

In case of gas burners, remove the gas supply pipe.

Cleaning the turbulators, heating surface, flue outlet and flue

pipe

1. Remove turbulators Bwith a

quick tug towards the front; for this,

use turbulator extractor A,which

is part of the cleaning equipment.

2. Clean flues Cand combustion

chamber Dwith the brush.

Remove combustion residues with

a vacuum cleaner.

3. Remove combustion residues from

theflueandtheflueoutletthrough

the clean-out aperture in flue outlet

Eusing a vacuum cleaner.

Inserting the turbulators, fitting the boiler door and clean-out
