7. Conservation
7.1. Boiler’s conservation
Except for the elements described in „BOILER’S EXPLOITATION” preserving it is important that
the boiler was protected during its stagnation (summer time, householders’ absence). Boiler’s
interior, hest, exchanger, chimney ap should be cleaned through - it’s advisable to burn some
dry softwood (ex. spruce) in the boiler before its stopping over - it will burn out the waste
occuring during boiler’s exploitation. After boiler’s cleaning it should be left opened for aerating -
in the way you will avoid humidity condensation in the boiler.
NOTICE!
It is advisable to control the boiler annually in order to prepare it well for the next
heating season.
7.2. Fan’s conservation
Fan is an essential boiler’s part. Keeping it in clean have a bearing on its longlasting. It’s advisable
to disassembly fan’s body from time to time and to clean it through (the waste deposited). Fan’s
blades can be cleaned with a soft bristle brush.
NOTICE!
Boiler’s working with the bottom door opened is unacceptable because in such a
case the fan can get overheated.
7.3. Boiler’s cleaning
The ash arising while burning process go down to the ash pit via the nozzle. The ash pit should
be cleaned every 3-5 days. Gasication chamber should be cleaned out between next burning
up. Ash is to be cleaned out via the nozzle - watch out as not to damage the boiler’s bottom. For
cleaning there should be used original appliances (enclosed as standard equipment). During
gasication process pitch occurs. Its quantity depends on wood, its humidity and contributing
and returning water’s temperature. It’s advisable to clean out gasication chamber with a scraper
(once a month). Carbon deposit subsiding at the pipes causes diminish of the exchanger’s section
and in the same time decreasing of the heat exchange. As a result it effects the thrust decreasing
and obstructs in heat transmitting. In accordance to this the exchanger’s pipes should be cleaned
out every two weeks to assure their permeability. (In SUPER boiler they should be cleaned after
every fuel loading.)
Four steps to clean out the exchanger (except for the SUPER type)
1. Take off the boiler back upper casing.
2. Turn on the nuts with M13 - M17 spanners (depending on boiler type).
Important!
Before nuts turning on and turning off the thread should be preserved with a special
anti corrosion agent; do not turn on nuts with exertion.
3. Each of the pipes in the exchanger should be cleaned with a cleaning shield. They should be
cleaned precisely in the whole length - it is important to avoid soot’s gathering at the bottom
part of the exchanger’s pipe and its blocking. Clean the soot deposited at the back part of the
chamber.
Important!
As to avoid the soot sediment in lower part of an exchanger it is necessary to sweep
out the soot from the back part of the boiler chamber.
