1 General safety information and explanation of symbols
1.1 For your safety
Installation and operation
zInstallation and commissioning must only be carried
out by qualified installation engineers.
zObserve all instructions to ensure perfect functioning.
zOnly use the boiler for its intended purpose.
zWhen installing and operating, observe all country-
specific regulations and standards. These include local
requirements in respect of positioning, the air inlet and
outlet equipment and chimney, as well as fuel and
electrical connections.
zDo not modify any parts that carry flue gas.
Maintenance and conversion
Customers are advised
zTo sign an inspection/maintenance contract with an
authorised contractor, and have the heating system
serviced annually.
zThe operator is responsible for the safety and
environmental compliance of the heating system
(federal legislation on emissions).
zOnly use original spare parts.
Instructing the customer
zExplain to the customer how the heating system works,
and how to operate it.
zInform the customer that he must not carry out
any alterations or repairs.
Read and observe the safety information and
codes of conduct:
You endanger your life by not paying attention to
your own safety, e.g. in the case of a fire.
zNever risk your own life. Your own safety is paramount.
If you can smell gas, there is a risk of an explosion
VClose the gas shut-off valve (Æpage 45).
zOpen window(s).
zDo not operate electrical switches.
zExtinguish all naked flames.
zFrom outside the building: call gas supplier and
authorised contractor.
If you can smell flue gases, there is a risk of
poisoning
VSwitch off the heating system (Æpage 45).
zOpen windows and doors.
zInform an authorised contractor.
Risk to life from electric shock.
zElectrical connections must only be made by a
qualified electrician. Observe the wiring diagram!
zBefore installation: Shut off power supply (230 V AC)
to all poles on the boiler and all other components.
Secure against unintentional reconnection.
Risk of fire from explosive and inflammable
materials

paints, etc.) must not be used or stored near the boiler.
Caution: system damage
zKeep the combustion air/ambient air free from
aggressive substances (halogenated hydrocarbons,
for example, contained in spray cans, solvents or
cleaning agents, paints and adhesives). This prevents
corrosion.
zPrevent heavy contamination of the combustion air/
ambient air by dust, airborne seed, etc.

4.4 Assembling the boiler block
A distinction is made between delivery as a pre-
assembled block and delivery in loose sections. When
delivered as a block, the boiler sections are already fully
assembled and checked for leaks prior to despatch. If,
because of physical limitations, a boiler block cannot be
installed or brought inside the building, delivery in loose
sections would facilitate assembly on site.
The following describes the assembly of the boiler block
when delivered in loose sections.
For the further installation of a pre-assembled boiler
block, Æsee section 4.5, page 19.

To make installation easier, place the boiler
section to be fitted onto the nipple on the
upper hub first. The boiler section can then
be adjusted accordingly on the lower hub.
Before the nipples are inserted in the next
central section, the part-assembled boiler
block must be pulled together using the
boiler compression tool.

Fig. 3, page 10).
Caution: Boiler damage
by pulling the boiler sections together
incorrectly, or excessive compression.
zEnsure that the nipples are positioned
straight in the boiler sections after being
hammered in and that they have not been
damaged.
zNever compress more than one nipple
joint at a time.
zStop compressing when the hubs meet.

Caution: Risk of accident
from material fatigue. Improperly used or
poorly maintained compression tools may
break.
zNever work directly in front of the
compression tool while it is being
tensioned.
zEnsure that no one is standing in front of
the compression tool.
Caution: Compression tool damage
The compression tool may be damaged or
destroyed if you compress pull rods with
loose threaded connections.
zAlways check the pull rods before each
use and tighten as necessary. The pull rod
is correctly positioned if it is fully inserted
and no thread is showing.
zAlways keep the thread clean. Dirty
threads may damage the compression
tool during compression.
zAlways grease threads thoroughly.

Fig. 17 shows the central section with flow connection.
The nipples for fitting the next central section are inserted
into the corresponding hubs. The packing cord has
already been inserted into the packing groove. As with the
rear section (ÆFig. 12, page 15), there is also a break in
the elastic packing cord here. The boiler section has been
equipped with foot wedges for ease of installation. The
boiler section foot wedges are also used later for final lev-
elling of the boiler block.
