4.5. Cleaning the heatin g device and chimne y
It is necessary to provide approach to the piping (smoke path) for occasional cleaning by means of,
for example, a removable part o f the c asing at t he area o f the s moke flue. We r ecommend you t o
advise of the requirement the company whose technicians will install the fireplace insert for y ou.
Further, approach in the chimney for occasional cleanin g is required as w ell.
By regular cleaning of the smoke pipes and the firing space in the fireplace insert, you may optimise
the performance of the heating system and guarantee a trouble-free function and operation. By
regular chimne y c leaning, y ou avoid i nflammation o f f ouling s olid partic les caught on the chimney
walling.
4.6 Fire in the chim ney
In case of f ire in the c him ney, put o ut the fire in t he stove immediately: remove the b urning
fuel r emnants with a s hovel (put them aside in a s uitable n on-flamm able c ontainer) and call
the fire brigade imm ediately: Call the fire brigade or t he integrated rescue system centre.
4.7.
External combustion air suppl y
For the firing process, enough fresh air supply is needed.. While firing wood, the device needs up t o
15 m
3
of fresh air per hour. In case of newly built houses, the insulating materials used in the house
result in low airiness coefficient, due to plastic windows, etc.). Another i ssue may be exhaust
devices or other heat installations in operation in the room or within the space where the fireplace is
installed. In such well-insulated houses, the quality of the firing process is lower, being accompanied
with tarring and smoke path clogging (and/or smoke penetration and spread in the room). Make sure
that the air supply i n the room is s ufficient, by o pen w indows or d oor i n the nex t, better ventilated
room. It is more convenient if you – along with the i nstallation of the heating device – install a
ventilation hole to provide air supply, equipped with a regulating grate (should be protected against
clogging). It is recommended to verify whether the air supply is sufficient, by - for example – using
the procedure TPG 704 01 “G as consumption dev ices and appliances with gas fuel inst alled in
buildings“.
4.8. External air supply system
Modern fireplace i nserts are designed with an external combustion air supply. T his way, enough air
is supplied for making the firing process perfect, especially in case of houses with lo w airiness
coefficient (well insulated from t he external environme nt due to construct ion elements r educing
natural air circulation (plast ic windows, doors etc.). Such external additional air supply should be
connected to the system chimney, whose part is a vent. This is offered by means of, for example, a
chimney system made by SCHIDEL. Another opt ion is a connection with space where the air
circulation is sufficient – e.g. by means of a passage through the wall into the ex terior. The best
solution for the particular house should be suggested by the specialist chimney company or the
company responsible for t he installation of the fireplace insert.
5. OPERATING INSTRUC TIONS
5.1. Before first operati on
If the fireplace insert is supplie d without casing
Before the first putting into operation, y ou have to remove labels from the glass, accessor ies found in
the ashpan or inside the hearth, including transport clamps etc. Following the illustration in the
Technical Card, check that the movable partitions designed for di recting the flue gases, fireclay brick
shapes or the barrier are located properly (they may have moved out of the position during the
transportation or installation w ork). If you find any wrong position, correct i t; otherwise, the heating
device might not w ork properly.
When the fireplace insert has been positioned and connected to the chimney system, make (not very
big) fire, maintaining it for approx. one hour.
As soon as the devi ce gets cold again, it i s possible to install t he outer lining.
If the complete fireplace set is supplied
Following the inst ructions for installation, place and connect the fireplace insert t o the chimney
system (including the installation of protective sheets –if used – and i nsulation of the smoke piping).
After that, i nstall the li ning (follow the instructions and illustrations). Then, install the fireclay layer in
the hearth of the fireplace insert. For the very first fire, use smaller quantity of wood, maintaining the
fire for at least one hour.
The insert surface layer is provided with fire-resistant paint being softened during the first fire made
in the stove to become harder afterwards. During the soft phase, pay special attention to danger of
damage on th e surf ace by t ouching it w ith f ingers, tools, e tc. For t he very first use, the initi al fire
should be very small, to “warm up” the device gradually: it is recommended to load smaller quantities
to establish lower temperature. All materials ne ed the initial lower- temperature phase in order to “get
used to” the thermal stress. By such slow heating up, y ou avoid cracks in fireclay bricks, likely
damage on surface paint or material deformation in general. Th e odour generated during the paint
hardening process at the first putting into operation is just temporary – how ever, it is
recommended to ventilate the room intensively. If pets are present, move them to another room
for a while.
With the models equipped with the glass do or comprising of three parts, check the segments for
gaps (which may be formed during the transpor t or the first use).
What to do if you find a gap bet ween the glass segments: Partially release the holder nuts. Move
the glass segment s (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, follow this procedure: Put 2 or 3 smaller wooden logs onto the bottom or on the
grate. Add paper or permitted fire lighters, then brushwood, small firewood and thicker logs (the last
layer). You should always load a bigger quantity (i.e. enough wood , which means up to approx. 2/3
of the height of the f ireclay (vermiculite) lining. B y loading s uch bigger q uantity, y ou establish time
long e nough in order to heat the chimney t hus s et the proper conditions for the chimney f unction.
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. A fter setting the fire, keep the stoking 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 burning. T o adjust the f lame and the burning, y ou may apply the i nformation
specified in the Technica l Card or Chart 1.
You may poke the fire when needed, using the f ire hook or the poking lever ( if installed).
Caution! The stoking door (the firing chamber) and the ashpan door (if installed with your
particular model) must be kept shut all the time, except setting the fire, fuel reload or ash removal.
Caution! After e very standby for a longer time, before you set the fire again, check the fireplace
insert for clearness and cl eanness of the smoke flue, chimney and firing are a.
5.3. Feeding the fir e
To prevent the smoke spreading through out the room during the fire feeding, the follo wing is
recommended: Approx. 5 to 10 seconds before y ou 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. Pay attention to the door any
time you o pen it: d o not allow live c inder fal l out. W hen you reloaded t he w ood, shut t he stoking
door. When the fuel burns up (no carbon black flame) , bring the regulating system ba ck in the
previous position ( or close t he regulator, respectively). While feeding the fire, m ake sure t he wood
does not exceed the level of the fireclay (vermiculite) l ining within the firing area. The quantity of the
fuel relo aded s hould b e m ore o r l ess t he s ame as specified i n t he i nformation p rovided about the
hourly consumption for the particular m odel of the heating device (see t he Technical Card). If you
overload the stove w ith excessive fuel, y ou may cause permanent damage to the insert constr uction.
Caution! If you w ant to avoid unnecessary smoke spreading throughout the room during the
feeding, reload the wood after the previous load has burnt up to ci nders.
