Safety instructions
Please follow these safety instructions closely to prevent accidents and
material losses.
Safety regulations
Installation, initial start−up, inspection,
maintenance and repairs must only
be carried out by a competent
person (heating engineer/installation
contractor).
Observe all current safety
regulations as defined by DIN, EN,
DVGW, TRGI, TRF and VDE or locally
applicable standards.
See also the safety instructions sheet
in the Vitotec technical documentation
folder.
Before working on the equipment/
heating system, isolate the mains
electrical supply (e.g. by removing a
separate mains fuse or by means of
a mains electrical isolator) and
safeguard against unauthorised
reconnection.
When using gas as fuel, also close
the main gas shut−off valve and
safeguard against unauthorised
reopening.
Work on gas equipment
This must only be carried out by an
approved contractor.
Please observe all commissioning
work specified for gas installations to
TRGI or TRF and all local regulations.
Please observe all commissioning
work specified for gas systems.

Boiler adjustment and positioning
1. Insert adjustable feetDinto the
bottom rails.
Note
The adjustable feet and the sight
glass closure are included in the
combustion chamber.
2. Ensure the boiler is level. Special
foundations are not required.
Note
We recommend boiler installation
on anti−vibration boiler
supportsC(see page4).
For the anti−vibration boiler
supports, the ground should be
level to within 1mm, to ensure
even loading of the spring
elements.
Position the supports under the
boiler; for this, locate them
centrally underneath the bottom
rails.
When setting the boiler down less
than square on, a boiler support
can, temporarily, be overloaded.
This can be prevented by laying
timbers (j35mm) under the
front, centre and back of each
boiler support.

Water and steam side connections
¨Safety instruction
Only open the water and steam connections after the boiler has been
completely depressurised.
Please note
Install all pipe connections free of load and torque stresses.
Thoroughly flush out the heating system, especially before connecting the
boiler to an existing heating system.
