6.5.6
Cleaning and inspection openings
Danger
Clean exhaust gas pipelines!
It should be possible to clean the flue gas pipes and inspect their
free cross-section and leakproofness.
At least one cleaning and inspection opening must be installed in the
installation room of the EC five.
Exhaust gas pipes in buildings, which cannot be cleaned or inspected from
their port side must have an additional cleaning port in the upper part of
the exhaust system or above the roof.
The exhaust gas pipelines at the outer wall must have at least one
cleaning opening in the lower part of the exhaust gas facility. For exhaust
gas facilities with building heights of < 15.00 m in the vertical section, a
pipeline length of < 2,00 m in the horizontal section and a maximum
pipeline diameter of 150 mm with a maximum deflection (except for
deflection directly at the boiler and in the shaft) one cleaning and
inspection opening in the installation room of the EC five is sufficient.
The ducts for exhaust gas facilities must not have any openings other than
the necessary cleaning and inspection ports as well as openings for back
ventilation of the exhaust gas pipe.

Electrical connections
6.6.1
Electrical connection (general)
Danger of electric shock
Danger to life through incorrect work!
All electrical work in connection with the installation may only be
carried out by a trained electrician.
Mains supply AC 230 V +6% -10%, 50 Hz
In Germany the VDE 0100 and local regulations must be followed during
installation; in all other countries, follow the relevant regulations.
The electrical connection should be made with correct and non-reversible
polarity. In Germany the connection can be executed as an accessible
plug and socket connection with non-reversible polarity or as a fixed
connection. In all other countries, a fixed connection must be provided.
For the power supply, use the power cable attached to the boiler or cable
types H05VV-F 3 x 1 mm
2
or 3 x 1.5 mm
2
. The earthing cable must be
longer at the connection in order to guarantee that this connection is the
last cable to rupture in the event of a hazard.
Important
For boilers with a total rated output of more than 100 kW, a switch
(emergency switch) must be fitted in front of the boiler outside the
room where the boiler is installed. This switch should be identified
by a sign featuring the text "EMERGENCY SWITCH FOR
BOILER".
All connected components must be executed compliant with VDE
regulations. Always apply strain relief to connecting cables.
