Furnace
Installation
Before setting up the chimney to the flue installation, you should check the diameter on the wall in the
chimney to see whether it is Ø 210 mm or Ø 120 mm. If it is Ø 210 mm, connect directly, and if it is Ø 120
mm, you need to reduce the Ø 210 mm diameter to Ø 120 mm.
NOTE: The furnace must be placed at least 0.5 m from the surrounding household items and walls.
For proper placement and installation of the furnace, you first need to check the airflow in the chimney
because good airflow is a prerequisite for the furnace to work properly. Checking the airflow volume is
best done using candles, see Figure 3.
Weak airflow Good airflow
Very strong airflow

The airflow intensity depends on the following:
a) proper conditions of the chimney,
b) atmospheric conditions (the seasons)
c) proper conditions of the furnace and other heating appliances connected to the chimney,
d) position of the home (whether it is on a hill, in plain or valley)
A proper chimney should meet the following requirements:
1. Exceed the rooftop (ridge) by at least 50 cm.
2. Surpass the house beside it, which is quite close to the chimney, then a tree, or some other obstacle
.
3. Have a cross section of at least 14 x 14 cm (half a brick).
4. Be on the inner walls of the house; if it is on the outer walls, it should be well insulated.
5. The extension needs to be firmly connected if the chimney is extended.
6. Be well cleaned, i.e., make sure there are no bird nests, dirt, soot, various obstacles, cavities, etc. If
two chimneys are parallel, then they must have special openings for cleaning, which should be tightly
closed, and there can be no cavities between the mouths of the chimneys.
When connecting the furnace to the chimney, make sure that flue pipe does not go deep into the chimney
opening, as this reduces the space for the smoke to come out.
Then, preferably, seal the joint, flue pipe - chimney. Two furnaces must not be installed at the same
height if they are connected to the same chimney, unless there is a distance of 50 cm between the
openings. For a furnace that is not being used but it is connected to the chimney, you should close the
airflow regulator, doors and regulators for the air incoming into the firebox.
Atmospheric conditions also affect the intensity of airflow. In the winter, the airflow is more intense
because the outside air is colder and heavier, so it pushes the hot flue gases more. In the summer, the
ignition is often hampered, precisely because the outdoor air is warm, so the airflow is less intense.
The position of the home (whether it is on a hill or in a plain) especially in windy weather, affects the
reduction of the airflow in the plain and increases the airflow on the hill. With previously tested and fulfilled
requirements and with the proper installation and connection of the furnace, functionality and safety in
operation will be provided.
When installing the furnace, you must adhere to applicable regulations on construction and fire protection
requirements. The place where you put the furnace should be horizontal and must have sufficient
capacity, otherwise you must implement appropriate measures in order to have uniform load distribution.
When it comes to combustible floors (wood, plastic, textiles ...), you need to place sheet steel, copper or
other non-flammable materials under the fireplace on the floor. This base should exceed the furnace
profile by at least 30 cm, and on the handling side, the base must be greater than the furnace by 50 cm.
The space between the wooden or plastic pieces of furniture and other flammable objects that need to be
