EVALUATION OF THE BOILER OPERATION
If after the fire up the boiler operates well, and later its capacity and draught decreases, it means that
the chimney flue is insufficiently tight: check whether the doors of the chimney flue cleanup are closed or
there are any other problems of tightness - remove them.
If after the burn up rhythmical noise is heard in the boiler and sometimes smoke erupts, it means
that the draught of the chimney flue is too strong – the boiler has no capacity and his operation is
uneconomic. In this case the air must be injected into the chimney flue through special openings. Turn a
lever in the clockwise direction so that pulsing of a boiler would disappear.
If fuel burns well but the temperature indicator slowly raises up and condensate leaks from the
chimney flue, it means that the heated water flow is exceeded: switch on a circular pump into the lowest
position and reduce a flow by the boiler balance tape or flows in the heating elements till the condensate
stops leaking from the chimney flue and the boiler temperature indicator reaches 70 – 80ºC.

BOILER CLEANUP AND MAINTENANCE
When firewood logs are burnt, ashes from the boiler must be removed every month. When burning
peat or coal, ash must be cleaned every month before firing. It is natural that the inner walls of the boiler
are slightly coated with tar but if the draught of the chimney flue is bad, if air passes through the under
part or lower doors, if during combustion the boiler is kindled and the air distributor is moved, if the
heated water flow is too intense too much tar could be build-up and the boiler can be clogged. Therefore
all the said defects must be eliminated.
When the draught is reduced, heat detraction cracks between the air heating compartment (2) and inner
walls of the boiler must be checked and cleaned up. They can be cleaned with a flexible brush through the
inner smoke opening above the fuel firebox door. It is more convenient to clean through a smoke
discharge opening (after dismantling a connection with the chimney flue) or through a special opening in
the connection.
The boiler shall not clog if the heating system is correctly mounted; chimney flue is in a good
order and is used following the recommendations of the manual.
Air distributor is lowered, can scoop
up old ash therefore their cracks must be sometimes checked and cleaned up.
If a crack between the lower plates is reduced or disappear, it must be restored after dismantling of
the distributor. A cable of the lifting mechanism must be lubricated so that it won‟t get warn and the
distributor would be lifted up more easy. We recommend lubricating the door closing hooks either.
Sometimes it must be checked whether the sealing of the doors and a place between the concrete floors
and the boiler is in a good condition. Remove the problems of sealing using heat resistance materials
mentioned above. So that the doors would be closed tightly, sealing materials should be replaced.
