4.03 Connection to the chimney
It is recommended to connect the boiler to a good working chimney built according to the regulations.
The connection between boiler and chimney must be done by using suitable material proof against
high temperature and corrosion. Its length must be as short as possible, with the least number of curves.
Where flue sections have to be connected it is advised pay attention to avoid leaking and provided
good insulation through all the flue length to avoid condensing problem.
