4. All the elements of the installation must be ensured against freezing, especially if the expansion
vessel or other parts of it have been located in non-heated premises.
5. In the installations with forced circulation the pump must be provided with UPS – an accumulator
with a transducer 12 V/220/V50 Hz on autonomous regime.
It is recommended that the circulation pump be switched on and off by a thermostat, duplicated with a
manual electrical switch.
6. The first service cleaning of the pump filter must be done immediately after testing the installation.
7. If an old installation is used, then it must be repeatedly sluiced to remove the accumulated residue,
which would precipitate on the surfaces of the water jacket.
8. Coal with increased sulphur content shall not be used and don't allow the coal get wet.
9. Fresh and wet wood or vegetation shall not be used. The logs shall be stored at least two years in a
dry and airy place.
10. The circulating water shall not be drained out during the non-heating season.
During the 3-4 kindlings it is possible to form condensation on the surfaces of the water jacket. The
forming soot decreases the sudden temperature difference and the quantity of the condensate.
The boiler is operated only by adult persons, who are acquainted beforehand with the operation
instructions. It is not allowed the presence of children without supervision in proximity of the boiler,
especially when it is on an operating mode.
Fuel
As a fuel only natural wood chemically untreated, as well as black stone coal must be used.
pellet burners use only wood pellet type C according to item 1 of EN 303-5 with humidity
below 10%.
It is important that the wood be dry.
Dry are called those logs which have humidity under 20 %. This is achieved when they stay in a dry
and airy place at least for 2 years. The logs are kept chopped and arranged, as their thickness must be
between 5 and 15 cm.
Why humid wood shall not be used?
1.
The humidity in the wood decreases their warmth of burning. A big part of the heat is spent
on evaporation of the water, and the rest can turn out insufficient to ensure the necessary
heating. For example, 20 kg humid wood can mean 10 kg dry wood and 10 litres water,
added to the fire.
2.
The water vapour decreases the combustion temperature and contributes to the formation of
soot which accumulates and forms a black hard layer on the walls of the combustion
chamber, the glass ceramics, the pipes and the chimney.
3.
The pollution of the environment increases because the gases leave the chimney unburned.
Kindling of the boiler when operating with wood and coal
- The kindling of the boiler is done with entirely open valve of the flue gases.
- It is forbidden burning fluids to be used for kindling
- Put kindlings and logs on the grate throughout the whole depth of the boiler through the door for
refueling, so that they kindle.
- Put a thin layer of coal on the burning logs.
