Lack of sufficient ventilation in the boiler room may cause more problems in the work of the boiler. The
main problem is the inability to achieve high temperature of output water, i.e. not achieving maximum
power, which leads to condensation in the boiler.
Take into account the required minimum space needed for accessing safety elements and for
cleaning and regular repair.
Determine whether the level of electrical protection is in accordance with the characteristics of
the room where the boiler will be located.
It is forbidden to expose the boiler to harsh weather conditions. The boiler is not designed for
outdoor use and does not contain a system against freezing.
It is forbidden to close the vents in the boiler room. Vents are necessary for proper combustion.
3.4 Connection to chimney
During assembly of the chimney, we distinguish two situations:
Situation 1:
The boiler is connected to the standard chimney (masonry or metal) that has its own
foundation and full cross-section from the foundation to the top.
Situation 2:
Boiler is connected to the prefabricated metal chimney attached to the facade.
Situation 1:
Ceramic or metal pipes of circular cross-section of minimum 130mm in diameter should be used
for chimney. Flue pipe must be insulated.
If the chimney already exists and is of square cross-section, then the minimum dimension of the
intersection is130x130mm.
It is not allowed to use the chimney for connecting multiple devices.
It is not allowed to use air ducts as chimney.
Top of the chimney should be protected with a chimney cap because of the impact of rain and
wind. Distance from the cap to chimney should be 200mm.
Chimney should come out above the roof as per the recommendations,
picture 12.
If there are
some tall objects near the chimney, this should also be taken into account and the height of the
chimney additionally increased.
The chimney must also have a connection for extracting condensation, as well as a revision door.
During operation, the door should always be well sealed.
Situation 2:
In this situation, the flue pipe must go minimum 1.5m vertically upwards in the very room in
which the boiler is located, then to penetrate through the wall and be connected to chimney.
Flue pipe must have a T piece for condensation at the very outlet from the boiler, as well as the
possibility to be removed for cleaning.
