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 shall be repeatedly sluiced to remove the accumulated (lodged) residue, which would precipitate on the surfaces of the
water jacket.
8. Coal with increased sulfur content must 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
condensation.
- Baking up of the paint on all painted surfaces including the oven, as well. It is recommended airing of the premises.
After setting up the installation a 72-hour trial of the installation must be carried out in operation conditions. The attestation (notarization) by the installer for its
implementation is an integral part of the warranty card.
The facing of the fireboxes to build in with decorative elements shall be done only after carrying out the 72-hour trial.
The fireplace with a water jacket functions on the principle of a water heating boiler. The advantage of this kind of heating systems is the maximum use of the
heat released during the burning process. With this method the warmth from the firebox is lead away to premises which are distant and difficult to access for a
usual heat exchange, with the purpose of maintaining a uniform temperature and heat comfort. The fireplace with water jacket must not operate without water in
the heating system.
Fuel
Use only raw chemical natural wood, as well as wooden briquettes without adhesives.
It is important that the wood be dry - with humidity 16 ± 4% according to Annex B table, B.1 from EN 13240:2001, EN 13229:20012, EN 12815:2006. 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 wood shall be kept chopped
and arranged, as their thickness shall be between 5 and 15 cm. Why humid wood shall not be used?
The humidity in the wood decreases their warmth when burning. A big part of the heat is spent on evaporation of the water, and the rest can tum 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.
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. The pollution of the environment increases because the gases leave the chimney
unburnt
Kindling
The destination of the kindling is to warm the walls of the combustion chamber, the pipes and the chimney up to create draught through a stable blazing fire
without being necessary to open the door often to finish its preparation.
Before kindling clean the ash off the grate.
Open the valves for the primary air and for the flue gases completely.
Put two chopped pieces of wood in the combustion chamber, parallel to one another, from both sides of the grate.
Crush a paper and put it on the front part of the grate among the logs. Don't use glossy or impregnated paper.
Put small dry twigs or sticks on the paper. It is preferable easy burning kindling of softwood. Arrange the kindling, so that they may not fall down and stifle the
arising fire. Put some finely chopped logs on the kindling.
Kindle the paper. When the paper burns up, close the door of the combustion chamber.
Leave the valve of the primary air entirely open, while the flame spread all over the whole combustion chamber.
The thermo resistant paint, with which the fireplaces have been painted, is dried by compulsion in the producer's factories, and during the first one or two
kindles it self- bakes and becomes mechanically stable. During self baking of the paint, the premises must be aired from the released fumes.
Fuelling with wood
The radiated heat from the fire is not permanent in time, since the logs bum in the best way in cycles. Cycle is the time from the kindling of the logs put on the
embers till their reduction to a new layer of embers. Each cycle can ensure heating for various periods of time depending on how much logs and how big they
are and how they are fuelled.
The finely chopped logs, flung about crosswise burn more quickly because the entering air is able to reach all the pieces simultaneously. Such arrangement is
suitable when the heat is necessary to be given off intensively.
To achieve a long stable fire, gather the embers on the grate and put bigger logs compactly on them. The close and parallel arrangement of the logs prevents
penetrating of air and flames among them and preserves the interior of the pile to bum later. Open entirely the primary air. When the logs, most outside kindle,
decrease the air to achieve the intensity of burning desired by you.
How many logs are necessary depends on the output (power) of the fireplace and the desired heating. The amount of dry logs to fuel is 0.36 to 0,5 kg per hour
for each kilowatt useful heat output. The smaller number is for drier logs.
Signs of right burning
Burning shall run in the presence of flames till the logs convert into embers. The purpose is not to allow any smouldering and smoking. The smoke is no normal
product during the burning of the logs, and it is a consequence of bad combustion.
If there are fireproof bricks in the fireplace, they shall maintain their natural colour in yellow-brown, not in black.
With dried logs and sufficient primary air an immediate kindling must be achieved on each new refueling.
The glass ceramics of the door (if there is any) must remain clean.
The gases going out of the top of the chimney must be transparent or white. The grey smoke indicates that there is smouldering or bad burning.
Chimney
The chimney is intended to draw the combustion products out of the fireplace and to throw them away in the atmosphere beyond (outside the limits of) the
abode.
The upward draught or the "pulling" of the chimney is a result of the combination between its height and the difference in the temperatures of the flue gases and
the air outside. The column of hot flue gases in the chimney has smaller weight than the equivalent column cold air outside, so that the pressure in the lower
end in the warm chimney is smaller than the atmospheric (air) pressure outside. This quite small difference in the pressures creates the draught.
The lower draught is a prerequisite for difficult kindling or returning of flue gases, and it is overcome through quick kindling and burning of dry, thin and fast-
burning sticks and paper. After kindling of the fire and warming up of the chimney, its draught increases. For economical regime and high efficiency after the
warming up of the chimney, the draught must be decreased to 5-10 Pa, so that there may be no return of the flue gases (smoking) with a closed door.
The main causes of insufficient draught are the following:
layering of soot inside the chimney, which decreases its diameter and increases the resistance of the rising flue gases;
a cracked wall of the chimney or a loose rosette;
loose smoke pipes, or pipes pushed deeply in the chimney, as in this way they decrease the diameter or plug up the chimney;
The use of a single chimney with a small draught by several stoves on the same level (in close proximity);
Smoking also appears when the weather outside has suddenly got warmer - The warm gases from the kindling of the fire can't escape through the cold
chimney. In this case a bigger amount of quickly burning sticks and paper is used. The same effect takes place while attempting to kindle a fire on the first
(ground) floor, provided the same or an adjacent chimney is already being used by a fireplace on the top floor;
when the ceiling is not air-tight or there are open windows on an upper floor, the effect " staircase-chimney" takes place, creating a reverse draught;
