Operating Instructions and Installation Instructions

4.5. Cleaning the heating device and chimney
It is necessary to provide approach to the piping (smoke path) for occasional cleaning by means of,
for example, a removable part of the casing at the area of the smoke flue. We recommend you to
advise of the requirement the company whose technicians will install the fireplace insert for you.
Further, approach in the chimney for occasional cleaning is required as well.
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 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 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.
4.7. External combustion air supply
For the firing process, enough fresh air supply is needed.. While firing wood, the device needs up to
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 issue 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 in the room is sufficient, by open windows or door in the next, better ventilated
room. It is more convenient if you – along with the installation 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 “Gas consumption devices and appliances with gas fuel installed in
buildings“.
4.8. External air supply system
Modern fireplace inserts are designed with an external combustion air supply. This way, enough air
is supplied for making the firing process perfect, especially in case of houses with low airiness
coefficient (well insulated from the external environment due to construction elements reducing
natural air circulation (plastic 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 option is a connection with space where the air
circulation is sufficient – e.g. by means of a passage through the wall into the exterior. The best
solution for the particular house should be suggested by the specialist chimney company or the
company responsible for the installation of the fireplace insert.
5. OPERATING INSTRUCTIONS
5.1. Before first operation
If the fireplace insert is supplied without casing
Before the first putting into operation, you have to remove labels from the glass, accessories 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 directing 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 work). If you find any wrong position, correct it; otherwise, the heating
device might not work 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 device gets cold again, it is possible to install the outer lining.
If the complete fireplace set is supplied
Following the instructions for installation, place and connect the fireplace insert to the chimney
system (including the installation of protective sheets –if used – and insulation of the smoke piping).
After that, install the lining (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 the surface by touching it with fingers, tools, etc. For the very first use, the initial fire
should be very small, to “warm up” the device gradually: it is recommended to load smaller quantities
to establish lower temperature. All materials need the initial lower- temperature phase in order to “get
used to” the thermal stress. 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 putting into operation is just temporary – however, 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 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 you find a gap between the glass segments: Partially release the holder 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, 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 fireclay (vermiculite) lining. By loading such bigger quantity, you establish time
long enough in order to heat the chimney thus set the proper conditions 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 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. To adjust the flame and the burning, you may apply the 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! 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 every standby for a longer time, before you set the fire again, check the fireplace
insert 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. Pay attention to the door any
time you open it: do not allow 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 system back in the
previous position (or close the regulator, respectively). While feeding the fire, make sure the wood
does not exceed the level of the fireclay (vermiculite) lining within the firing area. The quantity of the
fuel reloaded should be more or less the same as specified in the information provided about the
hourly consumption for the particular model of the heating device (see the Technical Card). If you
overload the stove with excessive fuel, you may cause permanent damage to the insert 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.
