condensing boiler can lead to considerable
damage.
Warning
Persons involved in transport must wear
protective gloves and safety footwear.
Danger
Commissioning may only be carried out by an
approved installer. The installer checks the
tightness of pipes, the correct function of all
regulating, control and safety equipment, and
measures the combustion values. If this work is
not carried out correctly, there is a risk of
considerable damage to persons, environment
and property.
Danger
Risk of poisoning.
Never use water from the heating system as
drinking water. It is contaminated by deposits.
1 Safety
7703301 - 01 - 16072018 7

Danger
Risk of poisoning.
Never use condensate water as drinking water!
Condensate is not suitable for consumption by
people or animals.
Do not let the skin come into contact with
condensate.
Suitable protective clothing must be worn during
maintenance work.
Caution
Danger of freezing!
If there is a danger of freezing do not shut down
the heating system; continue to operate it at least
in economy mode with radiator valves open. You
should only shut down the heating system and
drain the boiler, domestic water storage tank and
radiators if it is not possible to heat in frost mode.
Caution
Secure against unintentional switch-on!
When the heating system is empty, ensure that
the boiler cannot be switched on unintentionally.
Danger
This appliance can be used by children aged from
8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of
experience and knowledge if they have been
given supervision or instruction concerning use of
the appliance in a safe way and understand the
hazards involved. Children shall not play with the
appliance. Cleaning and user maintenance shall
not be made by children without supervision.
Danger
The heating system must not continue to be
operated if damaged!
Danger
Risk of death due to modifications to the boiler!
Unauthorised conversions and modifications to
the boiler are not permitted, as these can put
people at risk and cause damage to the boiler.
Failure to comply with these instructions renders
the approval for the boiler void.
1 Safety
8 7703301 - 01 - 16072018

Danger
Replacement of damaged parts may only be
performed by an installer.
Warning
Risk of damage!
The condensing boiler may only be installed in
rooms with clean combustion air. Foreign matter
such as pollen must never filter through the inlet
apertures to reach the inside of the appliance.
The boiler must not be started up if there is heavy
dust development e.g. during construction work.
There could be damage to the boiler.
Caution
Keep the inflow area clear.
Never block or close off ventilation apertures. The
inflow area for combustion air must be kept clear.
Danger
Danger to life due to explosion/fire.
Do not store any explosive or easily flammable
materials close to the appliance.
Caution
Risk of burns!
For safety reasons, the discharge pipe from the
safety valve must always be open so that water
can escape during heating operation. The
operating state of the safety valve must be
checked from time to time.
