the flue pipe is to be placed through the walls and roof, the plan and structure of the room should be thoroughly
analysed and studied first, so that the pipe may be placed properly in accordance with the fire prevention standards.
First, it should be ensured that there is sufficient combustion air in the room where the stove is located. Occasional
inspection is recommended to ensure that combustion air is properly supplied to the biofuel combustion chamber. The
stove operates on 230 V – 50 Hz. Ensure that the electric cable is not entangled under the stove, that it is away from
hot places and that it cannot come in contact with any sharp edge that could cut it. If the stove is electrically
overloaded, this may shorten the service life of the electronic parts of the stove.
Never turn off power supply by pulling out the plug while flames are still burning in the stove. This may
jeopardize the proper operation of the stove.
3.2 THE SMOKE DISCHARGE SYSTEM
The smoke discharge must be executed in accordance with the existing standards. The flue pipe should be thoroughly
sealed. See Figures 1 to 7.
For smoke discharge, classic brick chimneys can be used, or chimneys may be made of pipes that must be thoroughly
insulated (double wall) and sealed in order to prevent condensation in them.
The discharge pipe must not be connected with other systems of any type, such as the systems for discharging smoke
from the combustion chamber, exhaust grid or air distribution systems, etc. Furthermore, the flue pipe must not be
located in closed or semi-closed rooms such as garages, narrow corridors, under closed huts or any other place where
smoke may appear. When the stove is to be connected to the flue piping, a professional chimney sweep should be
called to verify that there are no even tiniest cracks or fissures in the chimney. If the smoke discharge chimney has any
cracks, the flue pipe must be wrapped in new material in order to ensure proper functioning.
For this purpose, rigid pipes made of non-ferrous steel (with a minimum thickness of 1.5 mm) can be used, or pipes
made of stainless steel (with a minimum thickness of 0.5 mm).
The smoke discharge system (chimney) made of metal pipes must be grounded in accordance with applicable
standards and legal regulations. Grounding is prescribed by the law.
This grounding connection must be independent of the stove grounding.
The flue pipe must be made in compliance with the standards regarding the dimensions and materials used for its
construction (Figure 1).
A) Wind resistant chimney top
B) Maximum cross section of 15 x 15 cm or a diameter of 15 cm, maximum height of 4-5 m.
C) Seal
D) Inspection – control opening.
Flue pipes in bad condition or made of inappropriate material (asbestos cement, galvanized sheet metal, etc. with
coarse and rough or porous surfaces) are illegitimate and they jeopardize and hamper the proper operation of the
stove.
Smoke can be discharged through a classic flue pipe (see the figures below) provided that the following regulations are
met:
− Check the maintenance condition of the flue pipe or the chimney. If the discharge flue pipe is old, it should be
replaced
by a new one. If the chimney is damaged, it should be repaired or refurbished by inserting a steel pipe properly
insulated with mineral wool.
Figure 1 Figure 2
− Smoke is discharged directly into the flue pipe (chimney) only if its cross section is up to 15 x 15 cm or if its
diameter is up to 15 cm and if it has a cover for the purposes of inspection and cleaning.
− If the cross section of the chimney is larger than 15x15cm or its diameter is larger than 15cm, the possible
control of increased draught (decreasing) in the chimney can be performed in three ways:
1. If there is an opening for the purpose of cleaning at the bottom of the chimney, it should be partially opened.
2. A steel pipe with a diameter of 10 cm should be inserted into the chimney if you have elements for such a
refurbishment of the chimney.
