ATTENTION!
If the ejection path of smoke creates such a bad draft, of a bad flow of air (many curves, improper
completion of the ejection of smoke, constriction, etc.) discharge of smoke can be bad, or in a situation
like this smoke discharging is not as good as it could be.
The smoke ejection system from the boiler operates under negative pressure in the stove chamber and
with mild pressure from the smoke drain pipe. It is very important that the smoke extraction system is
hermetically closed (sealed). This requires the use of a smooth tube on the inside. First of all you must
carefully study the plan and structure of the room when the smoke extraction pipe is set up through the
walls and roof, so that the installation of pipes is performed properly in accordance with the standards of
fire protection.
You should first ensure that the room where the boiler is located has enough air for combustion. It is
advisable to periodically perform check so as to ensure that the combustion air comes right up to the
combustion chamber. The stove operates at 220 V ~ 50 Hz. Make sure that the electrical cord is not
underneath the boiler, to be away from the boiler, to be away from hot spots, and not to touch any sharp
edges that it could penetrate. If the boiler is electrically overloaded, this can lead to shortening of the
lifetime of the electronics of the boiler.
Never turn off the power supply by pulling the plug when there is a burning flame in the boiler.
This could jeopardize the proper functioning of the boiler.
4.2 THE SMOKE EXHAUST SYSTEM
The smoke exhaust must be carried out in accordance with existing standards. Exhaust gas tube should
be well sealed (see Figures 2-9).
For smoke exhaustion, one can also use classic brick chimneys while flues can also be made of pipes
that need to be well insulated (double wall) and sealed, to avoid creating condensation in them.
The drain tube absolutely must not be connected to other systems of any kind, such as the systems
where the smoke is removed from the combustion chamber, exhaust grilles or air distribution system, etc.
Also, the smoke exhaust must not be set up in enclosed or semi-enclosed areas such as garages, narrow
corridors, underground passages, or at any other similar places. When the boiler is connected to the
exhaust gas pipeline, it is necessary to bring professional chimney sweep to verify that the chimney does
not even have the tiniest cracks or fissures. If in the exhaust gas chimney there are such cracks, the pipe
for smoke exhaustion must be wrapped in insulation for proper functioning.
For this purpose, the tubes that can be used are solid and made of painted steel (minimum thickness 1.5
mm) or from stainless steel (minimum thickness 0.5 mm).
The smoke extraction system (chimney) built out of metal pipes must have grounding in accordance with
existing standards and regulations.
Grounding is required by law.
The grounding connection must be separated from the grounding for the boiler.
The smoke exhaustion pipe must be done according to the standards in terms of dimensions
and materials used for its construction (Table 1).
