4.7. Cleaning the heating devic e and chimney
In the c ourse of th e installation of the fireplace stove a nd connection to the c himney vent,
approach in the chimney for occasional cleaning of chimney pipes and the chimney as well
is required. By regular cleaning o f the s moke pi pes and the firing space in the fireplace
stove, you may optimise the performance o f the heating sy stem. B y regular chimney
cleaning, you avoid inflammation of fouling solid particles caught on the chimney walling.
4.8. Fire in the chimney
In case of fire in the chimney, put out the fire in the stove immediately: remove the burning
fuel remnants with a shovel (put them aside in a suitable non-flammable container) and call
the fire brigade immediately: Call the fire brigade or the integrated rescue system centre.
4.9. External combustion air suppl y system
For t he f iring process, enough fresh air supply is needed. While firing w ood, the device
needs up to 15 m3 of fresh air p er hour. In c ase of newly built h ouses, the insulating
materials used in the house result in low airiness coefficient for the house, due to plastic
windows, etc.). A nother issue may be e xhaust devices o r other hea t installations i n
operation in the room or within the space where the fireplace is installed.
In such w ell-insulated houses , the qual ity of the firing process is lower, being accompanied
with tarring and smoke pa th clogging (and/or smoke penetration an d spread in the r oom).
Make sure that the air supply i n the ro om is sufficient, by open windows or door in th e next,
better ventilated room. It is more convenient if you – along with the installation of the
heating device – in stall a ventilation ho le to provide ai r supply, equipped with a regulating
grate (protected against clogging).
5. OPERATING INSTRUCTIONS
5.1. Before first operation
Before the first putting into operation, you have to remove labels from the glass,
accessories found in the ashpan o r inside the h earth, including transport clamps etc.
Following the i llustration in the T echnical Card, c heck that the movable partitions designed
for directing the flue gases, fireclay brick shapes or the barrier are l ocated properly (they
may h ave moved out of the position during the transportation or installation work). If you
find any wrong position, correct it; otherwise, the heating device might not work properly.
The firep lace stove su rface laye r is provided with fire-resistant paint being softened to
become harder after the first fire made in the fireplace st ove. During the soft phase, pay
special attention to danger of damage on the s urface by touching it w ith fingers, tools, etc.
For the very fir st use, the initial fire should b e very small, to “warm up” the device gradually:
it is recommended to l oad smaller quantities to establish lo wer temperature. All materials
need the initial lower- temperature phase in order to “get used to” the t hermal stress. By
such slow heating up, you avoid cracks in fi reclay br icks, likely damage on surface paint or
material deformation in general.
The odour gene rated during the paint hardening process at the first putting into operation
is just tempora ry – however, it is recommended to ventilate t he room intensively. If pets are
present, move them to another room for a while.
With the models equipped with the g lass door comprising of three parts, che ck the
segments for gaps (which may be formed during the transport or the first use).
What to do if you find a ga p bet ween the glass segmen ts: Partially release the holder
nuts. Move the glass se gments (carefully!) closer to e ach other: the e dges 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 on t he grate. Add paper or permitted fire lighters, then brushwood, sm all firewood and
thicker logs (the l ast layer). You s hould al ways load a bigger quantity (i.e. enough wood,
which means up to approx. 2/3 of the height of the firecla y (vermiculite) lining. By loading
such bigger q uantity, you establish time long enough in order to heat the c himney thus set
the proper condi tions for the chimney function. Open the primary 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 wood flares up properly, use the air supply regulators to set not very intensive, rather
slow bur ning. To adjust the flame and the burning, you may apply t he information specified
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! B efore any new fire, check t he water quantity (pressure). With forced
circulation sy stems, c heck t he functio n o f the circulating pump. Check the grate for
dirt (clogging), remove (rake) the excessive ash a w ay from the grate.
Caution! Th e stoking door (the firing chamber) and the ashpan door (if installed w ith
your p articular model) must be k ept s hut all the time, e xcept s etting the fire, fuel
reload or ash removal.
Caution! After e very standby for a longer time, b efore you set th e fire again, check
the fireplace stove for clearness and cleanness of the smoke flue, chimney and firing
area.
5.3. Feeding the fire
To preve nt the smo ke s preading thro ughout the ro om d uring the fire fe eding, the fol lowing
is recommended: A pprox. 5 to 10 seconds before y ou open the stoki ng door, ope n the
primary air regulator w ide. Then, open the stoki ng door a bit only , wait for a couple of
seconds to allow t he smoke exhausting through t he chimney. After t hat, open the do or
wide. Pay attention to the door any time you open it: do not allo w live cinder fall out. When
you reloaded the wood, shut the stoking door. When the fuel burns up (no carbon black
flame), bring the regulating s ystem back in the previous p osition (or close the regula tor,
respectively). Whil e feed ing the fire, make sure the w ood does not exceed the level of t he
fireclay (vermiculite) linin g in t he firing area. The quantity o f the fuel r eloaded should b e
more or less the same as specified in the information provided about the hourly
consumption for the p articular model of t he heating device (see the T echnical Card). If y ou
overload the fire place stove with excessive fuel, you may c ause permanent damage to the
fireplace stove construction.
Caution! If you w ant t o a void unnecessary s moke s preading th roughout 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 s upply (t his is applied especially to the secondary air), the chimney effe ct and – last but
not l east – on the way ho w the fireplace sto ve i s o perated. It is recomme nded t o l oad on e
layer of the wood o nly: the logs should b e l aid evenly, farther from t he glass (a s f ar a s
possible). The rule is t he same for coal cakes a s w ell (keep the di stance 5 to 0 mm
between them). If the glass is dirty, we recommend increasing the firing intensity by
opening the primary air regulator, which usually supports the self-acting cleaning process.
