approved heating contractor.
BHave any faults immediately rectified in order to prevent
damage to the system.
BThe operator is responsible for the general and
environmental safety of the heating system.
BUse original spare parts only. Damage caused by the
use of parts not supplied by Buderus is not covered by
the Buderus warranty.
Danger through failure to consider your own safety
in an emergency such as a fire

is paramount.
Dangers posed by explosive and easily flammable
materials
BAny work on components in contact with gas may only
be carried out by an approved contractor.
BNever use or store easily flammable materials (paper,

reduce their size.
BThe boiler must not be operated, unless you
immediately remedy the fault.
Risk of water damage
BIn the event of severe risk of flooding, disconnect the
appliance from its power supply and shut off the fuel
supply before water enters the installation room.
BNever use the appliance if any part of it has been under
water.
BImmediately call a qualified service technician to
inspect the appliance and to replace any part of the
control system and any gas valves that have been
under water.
Combustion air
BKeep the combustion air free of corrosive substances
(e.g. halogenated hydrocarbons that contain chlorine
or fluorine compounds). This will help prevent
corrosion.
BAvoid very dusty atmospheres.
Instructing the customer

boiler works and have the heating system installer
(approved contractor) explain how to operate it.
Further important information
BNever switch off or interrupt the power supply to the
pump in case of overheating or if the gas supply does
not shut down. Instead, interrupt the gas supply at
another point outside the heating system.
BThe flue system must be checked annually. During this
inspection, have a contractor replace any parts that
show signs of damage through corrosion or other
causes.
