1.1 Safety instructions
If you smell flue gas
VSwitch off the boiler (Æpage 10).
VOpen windows and doors.
VInform an authorized heating contractor.
Installation
VCorrect and proper installation and adjustment of the
burner and the controls are the fundamental require-
ments for safe and economical operation of the boiler.
VThe boiler may only be installed or converted by an
approved heating contractor.
VDo not modify any parts that carry flue gas.
VThe hot water tank may only be used for heating
domestic hot water.
VNever shut off safety valves!
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.
VThe flue system must be inspected once a year. Have
all parts that show any signs of damage from corrosion
or other causes replaced.
VThe 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.
VRecommendation for users: sign a maintenance
and servicing contract with an approved heating con-
tractor covering annual servicing and maintenance.
VServicing and repairs may only be carried out by a
trained heating contractor.
VHave any faults immediately corrected in order to pre-
vent damage to the system.
VThe operator is responsible for the general and environ-
mental safety of the heating system.
VUse 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
VNever put yourself at risk. Your own safety must always
take the highest priority.
Dangers posed by explosive and flammable mate-
rials
VAny work on components that carry oil may only be car-
ried out by a certified heating contractor.
VDo not use or store flammable (paper, thinners, paints,
etc.) near the boiler.
VMaintain a clearance of at least 16 inches from the
boiler.
Risk of poisoning. Insufficient ventilation may
cause dangerous flue gas leaks.
VNever close off or reduce the size of air inlet or outlet
vents.
VThe boiler must not be operated until the obstruction
has been removed.
Risk of water damage
VDo not use the appliance if any part of it has been
under water.
VCall in a qualified customer service technician immedi-
ately to check the appliance and replace any controls
that have been under water.
Combustion air
VKeep 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
VThe operator must read the information on how the
boiler works and have the heating system installer
explain how to operate it.
