Inspection and maintenance
Heating systems should be regularly maintained for the
following reasons:
• to achieve a high level of efficiency and to operate the
system economically (low fuel consumption),
• to achieve a high level of operational safety,
• to maintain the cleanest combustion.
BRecommendation for customers: Sign a
maintenance and inspection contract with a trained
and certified contractor, covering an annual inspection
and demand-dependent maintenance.
BThe operator is responsible for the general and
environmental safety of the heating system.
BImmediately correct all faults to prevent system
damage.

by the use of spare parts not supplied by Buderus are
excluded from the Buderus warranty.
Explosive and easily combustible materials
BNever use or store easily flammable materials (paper,
thinners, paints etc.) near the appliance.
Combustion air/room air
BKeep the supply of combustion/room air free of
corrosive substances (e.g. halogenated hydrocarbons
that contain chlorine or fluorine compounds). This will
help prevent corrosion.
BPrevent heavy accumulation of dust.
Instructing the customer
BInstruct customers about the functions and operation
of the appliance.
BInform the customer that they must not carry out any
modifications or repairs.
BOnly use the boiler for its intended purpose and only
when it is in working order.
Disposal
BDispose of packaging in an environmentally
responsible manner.
BAll heating system components that have to be

The right fuel
This system requires the correct fuel to ensure a proper
operation. During commissioning, your system installer
will enter the correct type of fuel, which your system
requires, into the table below (ÆChapter 2.4, page 7).
Danger of water damage
BDo not use the appliance if any part of it has been
under water.
BCall in a trained and certified heating contractor
immediately to check the appliance and replace any
electrical or gas valve components that have been
under water.
Other important information
BIf the system overheats or the gas supply does not shut
off, do not switch off or disconnect the power supply to
the pump. Instead, shut off the gas supply somewhere
else to the heating system.
