In order to carry the main body of the boiler, there are two points of attachment on the right and left sides
of the boiler into which 1“ pipe ends can be screwed.
Now, the body of the boiler is able to be carried.
1.9 Chimney Connection
The KUENZEL pellet boiler is equipped with an exhaust gas ventilator. The ventilator can be fitted with
the exhaust gas escape which can point optionally to the right, to the left or in an upward direction. An
exhaust gas escape pointing downwards is not permissable.
The exhaust pipe to the chimney should be short, without any extra bends if possible and fixed in an
upward direction. When inserting it into the chimney, it should be rounded off at the top and fitted into a
position which allows the draught current to flow through well.
For any important information regarding the chimney calculations please refer to the technical data in
chapter ?? auf Seite ??. To use a chimney which has a smaller diameter than the smoke ducts is not
permissable.
Caution: Please be aware that with the low exhaust temperatures occuring constantly whilst in operation,
a damp–resistant fireplace (heat–flow number and resistance group I of the type DIN 18160/T1) may be
required.
If the boiler has to be connected to an already existing chimney, the dimensions of the chimney must
be calculated / a chimney report must be done beforehand. The agreement of your local chimney sweep
service must be obtained before installation.
Due to the ventilator, disruptive noises can occur at the chimney. For this reason, we recommend that the
connection should be made with a flexible exhaust gas pipe input into the chimney.
Make sure that the exhaust gas pipe has been tested to be free of leaks, as otherwise exhaust fumes could
escape into the boiler room. This applies especially to the cleaning openings at the bends in the pipe.
1.10 Heating Connection
In order to avoid operational disruptions, we recommend to you that the heating connection should be
formed according to one of the published KUENZEL system packages. For this, please note chapter3
