3. Put two chopped pieces of wood in the combustion chamber, parallel to one
another, from both sides of the grate.
4. Crush a paper and put it on the front part of the grate among the logs. Don't
use glossy or impregnated paper.
5. Put small dry twigs or sticks on the paper. It is preferable easy burning kindling
of softwood. Arrange the kindling, so that it may not fall down and stifle the
arising fire. Put some finely chopped logs on the kindling.
6. Kindle the paper. When the paper burns up, close the door of the combustion
chamber.
7. Leave the valve of the primary air entirely open, until the flame spread all over
the whole combustion chamber.
The purpose is to kindle the firebox from the first attempt, with one matchstick
without unnecessary fuss and repeated adding of paper and kindling.
The thermo - resistant paint, with which the fireboxes 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 the self - baking the room is aired from
the released evaporations
III. Fuelling with wood
The radiated heat from the fire is not permanent in time, since the logs burn 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.
Do not add only one or two logs. Their bigger number is necessary to form a layer
of embers, which retains the warmth and maintains the burning.
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 burn
later. Open entirely the primary air. When the outer logs 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 0,5kg per hour for each
kilowatt useful heat output. The smaller number is for drier logs.
IV. Signs for proper burning
1. Burning must run in the presence of flames till the logs convert into embers.
The purpose is not to allow any smouldering and smoking. Th e smoke is no t
normal product during the burning of the logs, and it is a consequence of bad
combustion.
