4.3 VENTILATION
The area where the boiler is installed must always be suppplied with fresh air by
opening a window or a duct. Fresh air is required in order to burn the fuel safely
and efficiently. Otherwise once the burning starts, the oxygen level will drop and
the burning will detoriate. Detoriation of burning will cause decreasing burning
efficiency and filling chimney with soot and will require frequent cleaning.
4.4 CHIMNEY
l The chimney that will be connected to the boiler must be independent. The chimney
must be connected to provide a minimum draught. A boiler without chimney connection
should not be operated.
l
Chimney connection pipe and pipe systematic should be installed and checked by
authorized people only. We remind you that the biggest factor in boiler efficiency is
chimney design and draught.
l Proper chimney connection pipe should not be smaller than the boiler's chimney
diameter, horizontal length must not be shorter than 60 cm and longer than 2 meters and
pipe must be connected to the chimney with minimum 10 degree of angle.
l We suggest not to use enamel stove pipes as they cause tars in chimney connection pipe
or chimney system.
l In case of an elbow use in chimney connection, the elbows must have round and wide
angle. Quantity of an elbow must be maximum 2 pieces.
l
Chimney connection must be installed to allow demounting from the boiler and avoid
gas leaking.
l Chimney connection pipe must not be extended to the outside and must be connected
to a chimney.
l Chimney connection pipe's contact with flammable material must be avoided.
l Chimney connection pipe shouldn't be pushed inside the chimney.
The direction of the chimney should not be changed. If there is a need to change
directions,it must be positioned horizontally by 60 degrees.
l The chimney must be leak proof and air transperancy from inside and outside must be
avoided.
Do not connect more than one boiler and another device to same chimney. This
would decrease chimney draught and boiler efficiency. There should be no contact
between the chimneys that are placed side by side
.
l
There should be no sectional narrowing in any part of the chimney.
