Explanation of symbols and safety information
Danger from escaping flue gases
B Make sure that the vent pipes and gaskets are not
damaged.
B Use silicone as sealing compound.
B The boiler must not be fitted with a barometric damper
or a thermally controlled flue flap downstream of the
flue socket.
B Connect only one boiler to each venting system or
chimney flue.
B Connection of another boiler may cause serious injury
or death.
B The venting system piping must not feed into another
air extraction duct.
B Do not route the flue system piping through or inside
another air extraction duct, for example where there is
a masonry or prefabricated chimney flue.
Danger of explosion of flammable gases.
B Work on gas components may only be carried out by
qualified and authorized personnel.
B Mounting, gas and flue connection, initial
commissioning, electrical connection and maintenance
activities must only be carried out by a trained service
provider.
Dangers posed by explosive and easily
combustible materials
B Do not use or store easily-combustible materials
(paper, lace curtains, clothing, thinners, paints, etc.)
near the boiler.
B Maintain a clearance of 16.2 inches (415 mm) from the
boiler.
Combustion air
B Keep the combustion air free of corrosive substances
(e. g. halogenated hydrocarbons that contain chlorine
or fluorine compounds). This will help prevent
corrosion.
Danger from electric shock when the boiler is open.
B Before opening the boiler:
Disconnect the heating system from the electrical
power supply by means of the emergency shutoff
switch or the heating system circuit breaker on the
main fuse panel.
B It is not enough to only switch off the control unit.
B Take measures to ensure that the heating system
cannot be switched on again unintentionally.
Danger due to short-circuits
To prevent short circuits, only
B use genuine Buderus wiring.

approved heating contractor.

damage.
