21. CLEANING OF THE VENTILATOR´S OPERATION AREA
Operation space of the ventilator´s radial impeller has to be cleaned at least 1× a year. To do so,
release matrices of the ventilator´s flange and demount ventilator. Clean the operation area
from soot and mud. By demounting, take care to tighten matriaces of the ventilator´s flange
sufficiently.
ATTENTION! Demount ventilator, while boiler is out of order. Insufficiently cleaned
ventilator´s operation area may cause its limited function.
