Each time after the heating season and during prolonged shutdowns, the boiler should be thoroughly
cleaned and subjected to maintenance.
The proposed intervals of the individual activities carried out by the user under boiler
cleaning and maintenance procedures are approximate, and their frequency is strictly
dependent on the quality of fuel used and the working conditions of the boiler.
To remove the ash contained in the flue gas collector, remove the collector grille on top of the boiler
and remove the collector cover. Cleaning of the collector can be entrusted to the Service Partner of
HKS Lazar company.
Cleaning the exhaust flue and the located nearby exhaust fan is possible after removing the fan
(disassembly should be performed by the Service Partner) or after opening the flue cleaning hatch
and flue gas collector cleaning hatch. Regularly check the fan operation. Do not allow the exhaust
fan to immobilize by the pollutants accumulating in the flue gas collector and around the fan.
It is recommended to monitor the status and operation of the exhaust fan, with special attention paid
to the seals, possible leaks, noise level and its possible growth, uniformity of operation, the state of
bolted connections. Do not touch the engine with unprotected hands, because its temperature can
reach 75
o
C and even 100°C. Replacement of the fan motor condenser is recommended every two
years.
Before performing any activity related to the fan maintenance, disconnect the boiler from the
power supply and check that the fan impeller is not moving!
