7. Conservation

7.1. Boiler’s conservation

Except for the elements descried 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 occur-

ing 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.

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. Gasication 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

gasication process pitch occurs. Its quantity depends on wood, its humidity and contributing

and returning water’s temperature. It’s advisable to clean out gasication 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.

Four steps to clean out the exchanger (except for the SUPER 1 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

4. It’s advisable to add some potato rind from time to time (about 10l). Potato starch works as

catalyst and it makes the matter of sediment burning out easier.
