Explanation of symbols and safety instructions
H General safety instructions
Failure to observe the safety instructions can result in
serious personal injury and a risk to life as well as
material losses and damage to the environment.
▶ Carry out service work at least once a year. As part
of this, check that the entire system is working
correctly. Defects must be remedied immediately.
▶ Never put your life at risk. Your own safety is
paramount.
▶ Before commissioning the heating system, read
these instructions carefully.
H Risk of damage from operating errors
Operator errors can result in personal injury and
material damage.
▶ Ensure that only personnel who can operate this
appliance correctly have access to it.
▶ Installation and commissioning as well as servicing
and maintenance must only be carried out by an
approved contractor.
▶ Only operate the system when it contains a
sufficient volume of water (operating pressure).
Operation without a sufficient volume of water is
not permitted.
H Risk through oil leaks
If using oil as fuel, country-specific regulations hold
the operator responsible for asking a contractor to
correct any oil leaks the moment they are discovered.

H Risk of electrical shock
▶ Electrical work must only be carried out by a
qualified electrician.
▶ Before carrying out any work on the heating system,
disconnect the heating system from the power
supply across all poles (for example, press the
heating system emergency stop switch outside the
boiler room). It is not enough to switch off at the
control unit.
▶ Secure the heating system against unintentional
reconnection.
▶ Observe the country-specific rules and regulations
when making the electrical connection, during
initial commissioning, servicing and carrying out
maintenance.
▶ Also observe the connection diagrams of other
system components.
H Risk of scalding
Temperatures > 60 °C may be reached inside the
heating system.
▶ Prior to inspection and maintenance, let the heating
system cool down.
H Installation, conversion and operation
Insufficient ventilation can lead to dangerous flue gas
leaks.
▶ Only have the boiler installed or modified by an
approved heating contractor.
▶ Never modify any parts for flue gas routing.
▶ Ensure that flue pipes and gaskets are not
damaged.
▶ With open flue mode: do not cover or reduce the
size of ventilation apertures in doors, windows or
walls.
▶ Adjustable ventilation flaps are not admissible and
must not be used for permanent ventilation.
▶ With mechanical ventilation, combustion must only
start when the supply air flap is fully open (volt free
checkback signal to the boiler controller via failsafe
limit switch). Provide for control of supply air flaps.
▶ Ensure that the boiler installation location remains
free from the risk of frost.
▶ The heating system must be installed and operated
according to the following laws and guidelines:
statutory ordinances, gas safety regulations, IEE
ordinance, building regulations, local water
ordinance, The Health and Safety at Work Act 1974
and all other local regulations. Chemically
aggressive substances can cause the device to rust,
which would invalidate any warranty claim.
