13. HOW TO CLEAN SPACE UNDER EXCHANGER
It is necessary to clean space under exchanger pipes in regular intervals. This interval depends
on boiler operation time, but it has to be done at least 1× a week. Remove cover of the opening
for cleaning carefully, not to damage the sealing. After cleaning of space under exchanger,
install the cover – it has to be sufficiently screwed and air-proof.
ATTENTION! Otherwise there may come to insufficient air circulation in the boiler
and thereby to incorrect boiler function (ineffective combustion, decreased output,
low flue gas temperature, etc.).
