1.1 Safety instructions
If you smell flue gas
V Switch off the boiler (Æ page 10).
V Open windows and doors.
V Inform an authorized heating contractor.
Installation
V Correct and proper installation and adjustment of the

Water must be able to escape from the safety valve for
the hot water system and piping when the water is
being heated.
Maintenance and servicing
Heating systems should be regularly maintained for the
following reasons:
– to maintain a high level of efficiency and to operate the
system economically (low fuel consumption),
– to achieve a high level of operational reliability,
– to maintain the cleanest combustion.
V The flue system must be inspected once a year. Have
all parts that show any signs of damage from corrosion
or other causes replaced.
V The boiler must be serviced by qualified boiler service
company once a year. Servicing must include the
burner, the entire flue and combustion air system and
any air inlet/outlet vents. All parts that show any signs
of damage from corrosion or other causes must be
replaced.
V Recommendation for users: sign a maintenance
and servicing contract with an approved heating con-
tractor covering annual servicing and maintenance.
V Servicing and repairs may only be carried out by a
trained heating contractor.
V Have any faults immediately corrected in order to pre-
vent damage to the system.
V The operator is responsible for the general and environ-
mental safety of the heating system.
V Use only genuine Buderus spare parts. Damage
caused by the use of parts not supplied by Buderus is
not covered by the Buderus warranty.
Danger by failing to consider your own safety in an
emergency such as a fire
V Never put yourself at risk. Your own safety must always
take the highest priority.
Dangers posed by explosive and flammable materials
V Any work on components that carry oil may only be car-
ried out by a certified heating contractor.
V Do not use or store flammable (paper, thinners, paints,
etc.) near the boiler.
V Maintain a clearance of at least 16 inches from the
boiler.
Risk of poisoning. Insufficient ventilation may
cause dangerous flue gas leaks.
V Never close off or reduce the size of air inlet or outlet
vents.
V The boiler must not be operated until the obstruction
has been removed.
Risk of water damage
V Do not use the appliance if any part of it has been
under water.
V Call in a qualified customer service technician immedi-
ately to check the appliance and replace any controls
that have been under water.
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.
Instructing the operator
V The operator must read the information on how the
boiler works and have the heating system installer
explain how to operate it.
