small chunks of wood into the furnace when the chimney damper and air inlet are open.
Once fire spreads over the chunks, in stage two add the right quantity of fuel and set the
adjustment levers appropriately.
If a large quantity of wood is placed over a layer of embers (in particularly, fine pieces of
wood with thick bark), this may result in sudden production of considerable quantities of gas
in the furnace and its ignition. To eliminate that hazard, fuel ought to be added in a manner
preventing “stifling” of the flame and accumulation of gases. Combustion of gases ought to
take place on an ongoing basis, i.e. the user should aim at keeping at least a small flame
visible inside the furnace.
Apart from adjustment of combustion air inlet (bottom lever), intensity of the combustion
process and, as a consequence, thermal efficiency of the fireplace insert depend as well on
chimney parameters. In case of insufficient negative pressure (draught), the chimney damper
(top lever) may be opened when the fireplace is lit up; in that case, position of air supply
adjustment lever (bottom lever) is to be adjusted accordingly. However, this is not
recommended as it involves reduction of fireplace thermal efficiency.
In order to light up the fireplace insert properly for the first time (the product is processed
using lacquers resistant to high temperatures), please remember that:
•
construction materials used for building the fireplace are not homogeneous: steel and
chamotte elements are used,
•
the temperature which particular parts of the body are exposed to is not
homogeneous, either: for different elements of the fireplace insert, the temperature
changes and may even reach 500
°C,
•
during operation, the fireplace insert is subjected interchangeably to cycles of heating
and cooling, related to lighting up and extinguishing during one day, as well as cycles
of intensive usage and complete rest during warm months of the year,
•
before beginning proper usage, a brand new device ought to undergo the process of
removing internal tensions and hardening of lacquer. This involves several cycles of
heating up to nominal operating temperature followed by cooling down to ambient
temperature,
•
during the initial phase of using the fireplace insert, a smell typical for heating up metal
and annealing of fresh lacquer will be sensible. During the stabilisation stage, the
lacquer should be subjected to the influence of the temperature of 250
°C, it should –
several times and for a prolonged time
– exceed the temperature of 350°C; only this
will let it achieve the appropriate durability and it will be bound with the metal surface.
This may take from 1 to 2 weeks, depending on intensity of using the fireplace.
•
During the first lightings, it could release fumes or unpleasant odors caused by the
drying of the paint; it is not hazardous, it's just necessary to ventilate the room.
The following precautions are to be considered during the lighting up stage:
1) make sure that the room where the fireplace insert is installed has sufficient
ventilation,
2) during initial lighting up cycles, do not overload the combustion chamber
(approximately half of the level indicated in the operating manual), maintain the fire for
at least 3-8 hours at wood combustion rate below the one specified in the operating
manual,
3) repeat the procedure at least 4-5 times, if possible,
4) gradually increase the quantity of fuel (in compliance with guidelines contained in the
operating manual) and maintain the device in operation for as long as possible
– avoid
short cycles of lighting up and extinguishing the fireplace insert, at least during the
initial stage,
