Fitting sound insulation strips

CAUTION:
Injury from crushing.
▶ When lowering, do not reach under the boiler.
▶ When lowering, make sure that nobody is in the danger zone.
Consider additional sound insulation measures before installing the
boiler.
To reduce the noise, place the sound insulation strips provided below the
base frame, flush with the front and back of the boiler.
▶ Position the boiler at its installation site.
▶ Place sound insulation strips lengthways below the boiler frame at all
four corners.
▶ Carefully set the boiler down.

Levelling the boiler

Use metal shims to level the boiler.
To prevent air collecting in the boiler, level the boiler horizontally.
▶ Open the burner door ( chapter 6.9.1, page 20).
▶ Place a spirit level on the combustion chamber floor.
▶ Level the boiler horizontally using the spirit level in the combustion
chamber.

6.4.1
Danger to life through poisoning!
Insufficient ventilation can lead to dangerous flue gas leaks!
▶ Never close off or reduce the size of the supply and extract air
apertures.

▶ Never operate the boiler unless faults are rectified immediately.
▶ Inform the operator in writing of any faults and their associated risks.
Implementing the following recommendations concerning the
installation of flue systems should guarantee trouble-free operation of
the combustion system. Failure to observe these requirements can result
0010014759-001
in substantial operating problems during combustion and may even
result in explosions.
These problems frequently include acoustic disturbances, compromised
combustion stability or excessive vibrations on assemblies or their
components.
Low NOx combustion systems are to be viewed as being more sensitive
to operating faults on account of their combustion control. Therefore,
engineer and implement the flue system with particular care.
The flue system consists of a connection piece between the heat source
and the vertical flue system itself (chimney).
Due to utilization of the flue gas condensate in the heat source, the flue
system must be adapted to the flue gas condensate conditions.
