Do not use combustible liquid e.g. petrol, alcohol for lighting a fire and do not store similar kinds of liquid near your
fireplace insert!
The first lighting
The fireplace insert should start with a small fire at first so as not to harm it by very fast temperature rise. Smoke and the smell of burning which
may appear during the first lighting of a fire is a result of coating thermal curing. The room should be well aired during first heating.
The heating system must be full of water, bleeded and pressurized.
Inlet of el. energy must be ensured (circulating pump, circulating pump control).
Inlet of cold water from the water main into the safety valve must be ensured.
All valves of the system must be open.
Adequate warmth outlet must be ensured (water tank, radiators,…).
Functions of the safety valve, circulating pump and surplus heat outlet must be ensured.
Check if all removable parts of the fireplace (barrier, grate, ash-tray) are in the right position in accordance with the
Equipment Certificate.
Lighting a fire
Stoking a fireplace insert is operated through a firebox door. At first bank up the fire with 2 or 3 smaller logs ( 1,5 - 2 kg) on the bottom of the firebox
then some paper, paperboard or firelighter (externally untented), then wood chips and finally small pieces of wood. Now let the fire burn. When the fire
is burning well, add a few smaller logs. From the beginning, keep the external air inlet fully open. Then, get the inlet more closed or set up the required
output on the automatic regulation. Stock in the phase of the high heat in the combustion chamber.
The optimum amount of fuel is recommended in the Equipment Certificate.
Due to overloading of the insert, nonreturnable changes will occur!
We can provide a guaranty for our products only when the insert is not overloaded and service instructions are kept!
Setting of air inlet during hands-off operation
Hot water inserts are provided with the air input in bottom part underneath the door. With the help of this regulation you can regulate combustion air
input (primary air) and also the glass flushing.
The proportion of the air amount in each intake is regulated automatically. There is a possibility of
nearly closing of the regulation for long term operation.
Fuel addition
Apart from using the suitable fuel and having an adequate chimney draught, the clearness of the glass front
is influenced by the way the fireplace is used. It is recommended to add only one layer of fuel. About 5 -
10 seconds before you open the firebox door you should close the discharge valve (engaged position
closed, disengaged position open), to stop smoke leakage from the firebox to the room. After adding fuel
close the firebox door again. Then open all the discharge valves to reduce the rate of fuel burning. When
fuel burns, change the regulating again as above.
WARNING: DO NOT CLOSE INTENSELY AND AFTER THAT DO NOT OPEN INTENSELY EXTERNAL AIR
INPUT, THERE IS A POSSIBILITY OF EXPLOSION OF ACCUMULATED UNBURNT GAZES!
Moisture condensation and tarring of the fireplace
During the first lighting in a cold fireplace moisture condensation can be caused on fireplace sides. Water flows down into the firebox. This condensation
disappears when ash covers inner walls of the fireplace. Heating when temperature is low is not good even for the chimney service life. Tarring of the
fireplace comes in similar conditions (low output, low temperature) and what´s more during bad combustion (leak of combustion air). Tar disappears
when the min. temperature is 90°C. You can reach the temperature quickly by a radiator system shutdown. To prevent condensation and tarring we
recommend operating the fireplace with the temperature higher than 65°C.
Open fires
Open fires must be supervised constantly!
Add only one fuel layer into the firebox so as not to overhang the barrier in its front part. Add only the recommended amount of fuel.
The fireplace must not run with any other kind of fuel.
Fireplace inserts with pull-up door mechanism are set from production to be closed automatically by default due to a safety reasons. If they are set
differently by customer, it is at his own risk.
Position
Hot water fireplace inserts can be positioned only in rooms and in places which are risk free. There must not be any electric wires in walls and in
ceilings where a jacketed chimney insert is installed. In rooms where a fireplace insert is situated there must be a sufficient fresh-air inlet for
combustion if the fireplace insert isn’t connected to external air input. The base where the fireplace insert is situated must be made and must be large
enough to permit the firebox to work correctly.
The hot water fireplace insert must not be located
on stairways (except houses where a maximum of two flats are situated),
on corridors open to public,
in rooms, where easily combustible or explosive materials or mixtures are stored or manufactured,
in flats or areas which are aired only by means of ventilators or hot-air heaters or when the safe function of an open fire is not ensured with the help
of the recommended stand and tube.
Fireplace insert location and combustion air inflow
The area must be provided with at least one door which leads into an open space, or with a window which can be opened, or it must be connected with
other rooms. Only rooms of the same flat or dwelling are counted. If there is not enough, the room where the fireplace insert is located, must be
provided with a combustion air outlet tube:
Which leads directly into the fireplace insert (see pict. 01) and supplies minimum volume of convectional air. When the fireplace insert is connected
with outer air it must be installed on the original stand which is supplied by manufacturer.
-it is necessary to take deformation resistance into account during tubing batching, especially during curve, branch pipe or long pipe installation.
For combustion air which leads into an open space and supplies at least 360 m³/hour of combustion air 1
of firebox hole (see pict. 02). This tube
must be connected directly with the fireplace insert. If other fireboxes are located in a heating interconnection at least 540 m3 of combustion air 1
must be supplied into the firebox. To other fireboxes except this at least 1.6
of combustion air / hour and on each kW of total nominal heat output
when the initial pressure difference was at least 4 Pa as compared to an open space are needed (except fireboxes which are located in areas that do not
depend on air in a room, do not need a smoke flue or are located in areas where the operating safety of inserts cannot be endangered).
- if the fireplace insert isn’t connected to external air input, it is recommended that combusting air is supplied towards a fireplace in a convection area
- it is necessary to arrange tubing for combusting air in buildings with more than two floors, as stipulated by local building regulations, and tubings for
combusting air which connect antifire walls, so that fire and smoke cannot spread into other floors or fire
compartments.
It is possible to use data from the Equipment Certificate when setting the dimension of combusting air
flow piping (inflow of air / hour).
Ask your chimney sweep or fireplace builder for assistance
Adequate chimney
A fireplace insert must be connected into a chimney in accordance with national technical standards and regulations. Connection must be done only
with
the approval of chimney sweep
.
The chimney must be directly connected, dry and lined with fire-bricks. If the fireplace insert should be
connected to a chimney already built, it is necessary to clean the chimney and a chimney sweep must check its tightness and condition. A chimney
sweep also checks if the chimney is suitable for fireplace insert connection. In cases when the chimney does not exist or it is not suitable the new
chimney dimensions must be according to the Equipment Certificate. Low effective height limit of a stack flue is 5m if counted from the discharge of
combustion products slot. In single cases it is possible to connect even to a stack flue with less effective height than 5m. It must be documented by a
calculation of combustion products way that this height is enough for the connection. The fireplace insert must have its own chimney.
Chimney parameters
Chimney parameters in line with EN 13384-1 are found in the Equipment Certificate
