Installation of the burner
For burner connection dimensions, see chap-
ter “3.3.2 Base size”, page 19.
1.
Mount the burner to the boiler flange with the seal
and screws.
!
CAUTION
Failure to observe the guidelines and stand-
ards for the installation of burners can result
in damage to property and personal injury.
• On installing, comply with the guidelines
and instructions for mounting the burner to
the heat producer.
•
Only burners tested according to EN 267 or
EN 676 may be used.
2.
Fill the cavity between burner pipe and hinged flange
with the insulating wool provided.
3. If the weight of the burner (including attachments)
> 90 kg and the distance of the centre of gravity of the
burner to the door > 60 cm, support the burner hous-
ing weight directly with a strut to the floor.
4. Run a cooling line (hose or copper tube) from the
burner to the boiler sight glass to ensure that the boil-
er sight glass is cooled and remains clear.

Noise damping
• Gas pipelines are to be installed so that no vibrations
can be transferred to the building.
• The burner can be covered with a noise-damping hood.
• It is recommended to incorporate a noise damper
downstream of the boiler in the flue gas pipe.
4.5
Hydraulic connection
In accordance with EN 12828:2003 the following safety
devices are integrated in the boiler:
- temperature regulator
- temperature measuring device TBmax + 20 %
- safety temperature limiter
A complete failure of the water circuit must be taken into
account plant-specifically according to DIN EN 12828.
In Germany, a low water protection must be provided.
4.5.1 Pressure maintenance
A pressure expansion tank sized appropriately for the
heating plant, water volume and head has to be installed
on site.
4.5.2 Hydraulic connection
The minimum return temperature has to be ensured by
constant return flow control. A minimum water circulation
is not necessary.
