Air Connection; Chimney - Maktek 25 MKK-S Installation Use And Maintainence Manual

4.2 AIR CONNECTION
The area where the boiler is installed must always be suppplied with fresh air by using a
window or a duct. In order for a boiler to burn safely and efficiently, fresh air is required.
Otherwise once the burning starts, the oxygen level will drop causing the burning to be
inefficient. In turn, this will result in formation of soot in the boiler and chimney and will
require frequent cleaning.

4.3 CHIMNEY

• The chimney that will be connected to the boiler must be independent. The chimney
must be connected to provide minimum draught. A boiler without chimney connection
should not be operated.
• Chimney connection pipe and pipe systematic should be installed and checked by
authorized people only. May we remind you that the biggest factor in boiler efficiency
is chimney design and draught.
• Proper chimney connection pipe should not smaller than the boilers chimney diameter,
vertical 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.
• We suggest not to use enamel stove pipes as it creates tar in chimney connection pipe or
chimney system.
• In case of an elbow use in chimney connection, the elbows must be round with a wide
angle. Quantity of an angle must be minimum 2 pieces.
• Chimney connection must be installed to allow demounting from the boiler and avoid
gas leaking.
• Chimney connection pipe must not be extended to the outside and must be connected to a
pipe.
• The contact of chimney connection pipe with flammable material must be avoided.
• Chimney connection pipe must not be pushed inside the chimney.
• The direction of the pipe should not be changed, should there is a need ,it must be
positioned by 60 degrees.
• The chimney must be leak proof and air transperancy from inside and outside must be
avoided.
• No other boiler or device must be connected to same chimney. This would decrease
chimney draught and decrease boiler efficiency.
• Parallel chimneys should have no inter connection.
