6.4.1 Chimney connection
•
Flues should be made in
accordance with current
regulations.
•
To reduce the resistances of
flow of flue gases the
connection
with chimney
should be led in straight line
and possible change of
direction should be made
with gentle arcs.
•
Boilers can be assembled
into flues from brick with
aligned internal welds
•
Combustion duct should
begin from floor line
•
About 30cm. over floor
should be to situated
cleanout with tight lock
•
Intersection should be
approximate to square with
regard on smaller resistances of flue gases flow
•
The minimum intersection of chimney amounts 20 x 20 cm
•
The dams of brick between duct and wall should not be smaller than 12 cm
•
Chimney should be led out over roof
•
The location of chimney outlet depends from the degree of roof droop and
stages of the flammability. The roof with angle of droop to 12º - the chimneys
should stand over roof ridge 0.6m, roof with angle of droop over 12º - the
chimneys should stand over roof ridge in case of easily flammable coverings
0,6m however in case of incombustible or difficultly flammable covering, the
outlet can occur 0,3m over roof ridge.
•
Assembly of draught regulator is recommended, which in case of too big
underpressure in chimney opens and suck in the air from the boiler room and
does not pull it through boiler causing the temperature uncontrolled rise.
Interrupter this should be set on required value in dependence from power of
boiler
