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!
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.
Ash removal
At least once a day it is necessary to remove ash, with the help of a clinkering bar, from the bottom part of the fireplace insert. The
best time is in the morning because of the relatively cold state of the fireplace. It is possible to put wooden ash on compost or to
use it as manure. Fireplace inserts without grate: the layer of ash mustn´t reach the edge of the door. If the fireplace is covered with
a layer of ash, there is a risk of falling embers from the fire.
Before emptying of ash make sure, that there are no cinders in it.
Even with cold ash it is possible to find embers which can cause a fire in an ash bin.
Cleaning and maintenance
You should clean your fireplace at least twice per heating season or if needed. Clean it when it is cold. The most important for
cleaning are tubes of exchanger and smoke flue bend. For cleaning, you need to remove deflectors – see below and brush properly
all tubes with brush of Ø70mm. Remove covering of the bend and clean the smoke flue. The best way how to clean the glass is to use a
special cleaner for glass (do not use any cleaners with an abrasive action!).
Service opening door for cleaning
The corner fireplace inserts with sliding door – for cleaning, the door is possible to open sidewards, around the hinge. Before opening, it is
necessary to pull out the stop safety lock (1). Then, you unlock the locks on the top and bottom door parts using the special key (provided with
the insert)(2) and open the door. When closing the door, it is necessary to make sure, the 2 safety locks (3) are fully clipped in the door slots and
it is necessary to lock the door with the provided key again.
For flat door inserts with sliding door system, the door is open towards to you for cleaning. You unlock the lock (4) on the top door part using
the loop. In the cleaning position towards to you, the door is supported with stop drawbar (5). For closing the door again, you only push and
click strongly the door back.
For normal opening fireplace inserts, opening sideward, it is possible to unhang the door for better cleaning – follow the pictures under.

Position
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 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 allow the firebox work correctly.
Fireplace inserts must not be located
- on stairways (excerpt houses where a maximum of two flats are situated)
- on corridors open to the 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 when a safe function of an open fire is not ensured
with the help of the recommended stand and tube
Heating output
Bear in mind the information written on the insert design description. The heating potential of the fire depends on the output stated. Output is
applicable to rooms which correspond to the Heat Safety Protection. In rooms which are more than 200 cubic metres it is necessary to count
the heat consumption.
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 open, 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 tube:
which leads directly into the fireplace insert (see pict. 3) 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 m² 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 m² must be supplied into the firebox. To other fireboxes except this at least 1.6 m³ 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 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 case 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 5 m 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 5 m. 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.
