5.3 Kindling and firing
1. Fireplace stoves with grate - first put crumpled paper into the chamber and then lay chopp ed wood on it.
You can also used the solid fire-lighter PE-PO to start the fire. After starting fire, let it burn freely with all air
regulation elements ope n. It is f orbidden to use flammable liq uid (oil, p etroleum, etc.) f or starting fire!
After the fire begins to burn and the draft is strong enough, bigger lo gs or wood briquettes might be added
without the danger of s moke. Continue stoki ng the amount of fuel determined based on the nomi nal output of
the fireplace stove.
2. Fireplace stoves without grate - only secondar y air is used for burning; therefore wood logs need to be
stoked first, then chopped wood and finally small cuttings and paper. After starting fire, let it burn freel y with all
air regulation elements o pen. It is forbidden to use flammable liquid (oil, p etroleum, etc.) for st arting fire!
After the fire begins to burn and the draft is strong enough, bi gger logs or wood briquettes might be added
without the danger of sm oke. Stoke no more than the amount of fuel deter mined based on the nominal output of
the fireplace stove.
Fuel consumption is alw ays stat ed in the technical sheet. Burning intensit y is regulated b y air intak e controls
or, if a smoke shutter is installed, b y limiti ng the draft in the chimne y. Larger amount of fuel or a strong draft
and air take might cause overheating and damage of the fireplace stove. Too weak draft l eads to glass
blackening or to a smoke escaping into the room when opening the door and stoking fuel.
Warning: Fireplace doors must alway s be closed, with the exception of the first heating , stoking fuel and
removing ash. W hen the fireplace stove is not in operation for a lon ger period of time, it is necessar y to check
that the flue pipes, chim ney and combustion chamber are clear. I n general, the heating up and cooling of the
fireplace insert is accompanied by a specific sound; this is intended.
5.4 Stokin g fuel
In o rder to prevent smoke escaping int o the room when stoking fuel, please follow the followin g procedure:
Approximately 5 or 10 s econds before opening the fireplace doors op en the air intake re gulators and then onl y
slightly open the stoking doors, wait for few seconds for the exhaust gas to get sucked into the chimney and only
then fully open the door. When opening the stoking door, a special attention must be pai d to the danger of hot
fire-brands falling out. After stocking fuel, close the door aga in. After the fuel starts burning ( with clear fire ),
return the regulator back to its original position. The amount of stoked fue l should correspond to an hourly
consumption value for the concrete firepl ace stove (see the technical s heet). Ov erheating can permanentl y
damage the fireplace stove construction.
Warning: To prevent exhaust gas escaping into the room during stokin g add fuel after its burning down on
the glowing base.
5.5 Operation during the transition p eriod
The chimne y draft (sucking exhaust gas from the fireplace stove) might be weaker during the transition
period, i.e. when the outside temperature is higher than 15°C , during rainy and humi d days or during gust airs .
During this period the fir eplace stove should be operated with the minimum possi ble fuel so that the fire, as well
as the chimney draft could be improved by opening the air intakes.
Tip: During this period a so-called atmospheric plug can b e crea ted in the chimne y mouth due to the draft
conditions. The plug can caused smoke escaping into the room when lighting fuel. We recommend letting a
piece of paper burn dow n preferabl y in the upper part o f the combustion chamber before li ghting the kindling.
This se emingly negligible smoke is e nough to break through the atmospheric plug. Afterwards you can freely
light paper (or solid fire-lighter PE-PO) and be sure that eve n a humid chimney is clear.
In this period it is also possible to use the same lighting method as for the fireplace stoves without grate (with
no ashpan).
5.6 Ash removal
Make sure that the ashpan is cleaned when bein g half full in order to prevent the ash reaching too close to the
grate and thus damaging it . At the same time the ash would b lock the intake of air required for burning.
Removing ash from the ashpan shoul d be carried out when the fireplace s tove is cold and preferably ready for
the next he ating. A vac uum cleaner d esigned for cleaning ash with a filter for small filth can be a lso used for
cleaning the c old ashpans or heater without as hpans. Ash from bur nt wood can be used for composts or
fertilizing. Store the ash in closed non-flammable containers.
Warning: Make sure tha t the ash does not contain any glowing remains o f wood tha t could cause fire in the
waste container.
Warning: For some fireplace stove types the ashpan is located in a ba sin under the g rate and cannot be
removed from the side. The ashpan can be removed only when the heater is cold and not in o peration. The
ashpan is accessible after lifting the grate.
Be careful when removing hot ash!
5.7 Cleaning the glass
The clea nliness of the window is influenced not only by the using of suit able fue l, providing suff icient air
intake and chimne y draft but also b y the method of operating the fireplace stove. In this resp ect we recommend
stoking only one layer of fuel and distributing the fuel as evenly as possible and as far from the glass as
possible. This also applies for briquettes (the distance between them should be 5 to 10 mm). If the glass
becomes dirty, try increasing the burning intensity by opening the air intake and the glass will clean itself.
Sooty windows c an be clea ned in cold state using newspapers o r wet cloth dipped in wood ash. Usuall y
also liquid cleaning agen ts are used for cleaning the stove window. But these may in some cases, depending on
the composition of the cleaning agent and its int erac tion with combustion residues (ash particles, etc.), harm the
gaskets and/or the glass-ceramics and/or the decoration colour of the fireplace viewing panel.
The producer is not responsible for damage s, which are caused by attack in using of chemical agents.
6. Cleaning and maintenance
Your fireplace stove is a high-qualit y product and no significant d efects will appear during no rmal o peration.
The fireplace stove and exhaust pipes should be checked thoroughly before and a fter the heating season.
Clean the fireplace stove only after it cools off!
6.1 Cleaning the f ireplace stoves / disassem bly of chamotte
All sediments in flue pi pes and combusti on space must be removed du ring cleaning. Repair, ideall y by
removing, all fallen-off p arts of the chamotte lining. Th e integrity of t he chamotte lining must be monitored also
during the heating season. Spaces betwee n individual chamotte fittings serve as a hea t dilatation preve nting
cracking of the fittings and must not be filled by filling material as was usual with older types of soli d fue l
heaters. C racked chamotte fittings are still functional un til they fall out! Bulk shutter for directing the draft,
if used, should be removed during cleaning (this enables easier access to the space above them). The fireplace
stove cleaning (with th e exception of glass) should be done without water cleaner, i.e. using only vacuum
cleaner or steel brushes. Any modifications of the fireplace stove are unacceptable. Use only spare pa rts
