chimney entrance must be provided with a shrunk ring and a rosette. The blind cover can be
replaced with the smoke flue duct orifice depending on the flue duct being connected to the back or
the upper flue gas outlet. Tightness and firmness of connections is very important. The Type 1
stove (see the technical data table) is equipped with a self-closing door. This stove can be mounted
to the chimney flue together with another solid fuel stove under the following conditions:
a) if several appliances are connected to one chimney flue, only appliances from one floor and
from one user can be connected. Two users from the same floor can use one common chimney flue
only if approved by a relevant building office
b) in existing objects, two local closable solid fuel appliances can be connected to one common
chimney flue from two floors of one unit (e.g. a family house), if approved by the chimneyer.
The Type 2 stove (see the technical data table) does not have a self-closing door. Fire with the
door open is possible only if there is someone near the stove. When leaving the stove, close the
door of the furnace.
3.3 Installing a fireplace insert
For building in a fireplace insert expert knowledge is necessary. However, if you decide to install a
fireplace by yourself, please follow the instructions below:
1. The diameter of the chimney for connecting must be at least 18 cm and the chimney must
have an effective height of at least 5 m.
2. Eventual air condition piping must be at least 40 cm away from flammable building
structures or it must be proved that the heat transfer from the piping cannot cause ignition
of the structures. The convection airtemperature near the insert can be as high as 300 °C !
3. Build the fireplace so that its walls are at least 5 cm from the rear and side walls of the
fireplace insert sheathing. The spaces serve for cooling air circulation, which prevents the
surrounding structures from overheating. Do not cover these spaces from above nor from
below.
4. In the lower part of the fireplace (under the insert) vent holes min. 150 cm
2
for cold
convection air input must be made.
5. Make vent holes for heated convection air output in the uppermost part of the fireplace
superstructure. Total cross section of the vent holes must be at least 150 cm
2
.
6. The floor in front of the fireplace must be made from inflammable material (tile, stone, brick,
etc.) up to at least 40 cm in front of the fireplace and 20 cm at the sides over the contour of
the fireplace insert. The floor for the appliance must have corresponding load capacity.
7. Sufficient access for appliance, smoke flue duct and chimney cleaning must be ensured. The
inserts have upper flue gas outlet only.
8. Eventual modifications of the insert must be consulted with the manufacturer.
