Risk of poisoning. An insufficient supply of air can
result in dangerous escape of flue gas.
V
Ensure that air inlet or outlet vents are not closed off or
their size is reduced.
V
Ensure that no mechanical air extraction equipment
draws combustion air from the boiler room, e.g. cooker
extractor hoods, tumble dryers, ventilation equipment.
V
Only operate the boiler with chimneys that provide the
required draught during operation.
V
The boiler must not be operated until any deficiency
has been rectified.
V
Inform the system operator in writing of the problem
and associated danger.
Danger from escaping flue gases
V
Ensure that the flue pipes and seals are not damaged.
V
Use silicon as sealing compound.
Dangers posed by explosive and easily
combustible materials
V
Never use or store combustible materials (paper, lace
curtains, clothing, thinners, paints, etc.) in the vicinity of
the boiler.
Combustion air
V
Keep the combustion air free of corrosive substances
(e.g. halogenated hydrocarbons that contain chlorine
or fluorine compounds). In that way you will prevent
corrosion.
Risk of electric shock when the boiler is open
V
Before opening the boiler:
Disconnect the heating system from the power supply
by means of the emergency stop switch or the relevant
circuit breaker in the main fuse board.
V
It is not sufficient just to switch off the control unit.
V
Safeguard the heating system to prevent unintentional
re-connection.
Danger due to short-circuits

With open flue appliances: do not cover or reduce
the size of air vents in doors, windows or walls. If
draught-proof windows are fitted, ensure there is an
adequate supply of combustion air to the room.
V
The DHW cylinder may only be used for storing
domestic hot water.
Inspection/maintenance
Heating systems must be regularly maintained.
In that way, you will obtain a high level of efficiency and
low fuel consumption.
You will achieve a high level of operational safety and
reliability.
And you will obtain the cleanest possible combustion.
V
Recommendation for users: take out a maintenance
and service contract with an approved heating
contractor covering annual servicing and demand-
dependent maintenance.
V
Servicing and repairs may only be carried out by a
approved heating contractor.
V
Have any faults immediately rectified to prevent
damage to the system.

use of parts not supplied by Buderus is not covered by
the Buderus warranty.
Instructing the customer
V
Explain to the customer how the boiler works and how
to operate it.
V
Inform the customer not to carry out any alterations or
repairs.
