5.11. BOILER CLEANING
After continues operation of the boiler amounts of soot and ash accumulate to its walls, mainly
over the heat-exchanger sections and the flue outlet, which decrease the heat-exchanging
rate and the boiler heating ouput. The amounts of soot and tar depend on the operation
conditions and the types of used fuel. This may also lead to inadequate chimney draught.
Boiler cleaning has to be performed regularly, at least once per month, usually by using steel
brush through opened boiler door.
All inside walls of the boiler in the combustion chamber and the flue gasses passage channels
must be cleaned. If there is bigger quantity of tars over the combustion chamber inside walls,
then it must be removed by using a scraper or burned by firing hard wood at maximum
operation temperature.
Direction
The ash must be stored (the ash has to be taken out by using gloves) in
fireproof reliable containers and to be transported to opened spaces. Other
garbage or wastes should not be stored in these containers.
5.12. BOILER REPAIR
The boiler must be repaired only by authorized servicing technician or servicing organization.
The user or owner is allowed to perform only normal maintenance and to replace only a few
parts, for example sealing of insulating rope.
Warning
Always use only genuine spare parts when repairing the boiler.
