4.4. Installation of the fireplace stove within the room
Before a ny ins tallation w ork is started, y ou n eed t o verif y t he floor (ceiling) load capacity.
The load conditions for the particular type of the device must be met (depending on the
particular w eight). T he fireplace stove must be installed on a heat insulating ba se that
overlaps the fireplace stove ground plan dimensions on the sides and in the rear by at least
100 mm; the overlap in the front (the direction of t he feeding opening) is 300 mm. If a metal
base is used, the thickness must be at least 2 mm. Kindly pay attention to the information
provided in Supplement 1.
Caution! Make sure you provide space enough for ea sy approach to the device, smoke
flue and chimney for the purpose of cleaning.
4.5. Cleaning the heating devic e and chimney
In the course o f the installation of the f ireplace stove and connection t o the chimney ve nt,
approach in the chimney for occasional cleaning of chimney pipes and the chimney as well
is required. B y regular cleaning of the smoke pipes and the firing space in the fireplace
stove, you may optimise the pe rformance of the heating sy stem. By regular chimney
cleaning, you avoid inflammation of fouling solid particles caught on the chimney walling.
4.6 Fire in the chimney
In case of fire in the chim ney, p ut out the fire in the stove immediately: re move the
burning fuel remnants with a s hovel (put them aside i n a su itable no n-flammable
container) and call the fire brigade immediately: Call the fire br igade or the integrated
rescue system centre.
4.7. External combustion air suppl y system
For the firing process, enough fresh air supply is needed. While firing wood, the device
needs up t o 15 m3 of fresh a ir per h our. In case of newly built houses, the insulating
materials u sed in th e h ouse r esult i n l ow a iriness c oefficient f or t he h ouse, d ue t o p lastic
windows, etc.). Another issue ma y be exhaust d evices or other heat instal lations in
operation in the room or within the space where the fireplace is installed.
In such well-insulated houses, the qualit y of the firing process is lo wer, being accompanied
with tarring a nd smoke path clo gging (and/or s moke penetration a nd spread i n the roo m).
Make sure that the air supply i n the ro om is sufficient, by open windows or door in th e next,
better ven tilated room. It is more convenient if y ou – along with the in stallation o f the
heating device – install a ve ntilation hole t o provide air s upply, equipped w ith a regulating
grate (protected against clogging).
5. OPERATING INSTRUCTIONS
5.1. Before first operation
Before the first putting into operation, you have to r emo ve labels from the glass,
accessories found in the ashpan o r inside the h earth, including transport clamps etc.
Following the illustration in the Technical Card, check that the movable partitions designed
for d irecting t he fl ue g ases, f ireclay b rick s hapes o r th e b arrier a re l ocated p roperly ( they
may have mo ved o ut of t he posi tion during the t ransportation o r installation w ork). If y ou
find any wrong position, correct it; otherwise, the heating device might not work properly.
The fireplace stove surface layer is provided with fire-resistant paint being softened to
become harder a fter the f irst fire made i n the fireplace s tove. During t he soft p hase, p ay
special attention to da nger of damage on the surface by touching it with fingers, tools, etc.
For the very fir st use, the initial fire should b e very small, to “warm up” the device gradually:
it i s r ecommended t o l oad s maller q uantities t o e stablish l ower temp erature. A ll ma terials
need the initial l ower- t emperature pha se in o rder t o “ge t used t o” t he thermal st ress. By
such slow heating up, you avoid cracks in fireclay bricks, likely damage on surface paint or
material deformation in general. The odour generated during the paint hardening process at
the first pu tting into o peration i s just t emporary – h owever, it i s recommended t o ventilate
the room intensively. If pets are present, move them to another room for a while.
With the models equipped with the glass door comprising of three parts, check the
segments for gaps (which may be formed during the transport or the first use).
What to do if y ou find a gap betw een the glass segments:
Partially release the hol der
nuts. Move the glass segments (carefully!) closer to each other: the edges should touch
slightly. Slowly and carefully, tighten up the holder nuts.
5.2. Setting the fire
To set the fire easily, follo w this procedure: Put 2 or 3 smaller wooden logs onto the bottom
or o n t he g rate. Add paper or p ermitted f ire l ighters, then brushwood, sm all f irewood a nd
thicker l ogs (the last layer). You should always loa d a big ger qu antity (i.e. enough wood,
which means u p to a pprox. 2/3 o f the h eight of the fireclay ( vermiculite) lining. B y loading
such bigger quantity, you establish time long enough in order to heat the c himney thus set
the proper conditions for the chimney function. Open the p rimary air regulator wide
(maximum). Sometimes it is good to reduce the secondary air supply at this moment – the
fuel catches the fire better. After setting the fire, keep the door shut all the time. As soon as
the w ood flares u p properly, u se the a ir su pply regulators to set not ve ry i ntensive, rat her
slow bur ning. To adjust the flame and the burning, you may apply the information spec ified
in the Technical Card or Chart 1.
You may poke the fire when needed, using the fire hook or the poking lever (if installed).
Caution! Th e stoking door (the firing chamber) and the ashpan door (if installed w ith
your particula r model) must be kept shut all the time, except setting the fire, fuel
reload or ash removal.
Caution! A fter e very standby for a longer time, before you se t t he f ire again, check
the fireplace stove for clearness and cleanness of the smoke flue, chimney and firing
area.
5.3. Feeding the fire
To prevent the smoke spreading throughout the room during the fire feeding, the following
is recommended: Approx. 5 to 10 seconds before you open the stoking door, open the
primary air regulator wide. Then, open the stoking door a bit only, wait for a couple of
seconds to allow the smoke exhausting through the chimney. After that, open the door
wide. P ay attention to the door any time yo u open it: do not allow live cinder f all out. When
you reloaded the wood, sh ut the stoking door. When th e fuel burns up (n o carbon black
flame), bring the regulating system back in the previous position (or close the regulator,
respectively). While fe eding the fire, make s ure the wood does not exceed the level of t he
fireclay (vermiculite) lining in the f iring area. The quantity of the fuel reloaded should be
more or l ess the same a s specified i n the information p rovided about the h ourly
consumption for the particular model of the heating device (see the Technical Card). If you
overload the fireplace stove with excessive fuel, you m ay cause permanent damage to th e
fireplace stove construction.
Caution! If you want to avoid unnecessary smoke spreading throughout the room
during the feeding, reload the wood after the previous load has burnt up to cinders.
5.4. Glass cleanness
The cleanness of t he transparent glass depends on the type of the fuel, proper com bustion
air supp ly (th is i s app lied especially to the secondary ai r) , the chimney effect and – last
but not least – on the way h ow the fire place stove is o perated. It is recommended t o load
one layer of the wood only: the logs should be laid evenly, farther from the glass (as far as
possible). The rule is the same fo r coal cakes as well (keep the distance 5 to 1 0 mm
