2 Product details
These installation and servicing instructions contain
important information regarding the safe and proper
installation, commissioning and servicing of the boiler.
Product designation:
Logano G225 = fan-assisted, low temperature boiler
Logano plus GB225 = fan-assisted, low temperature
condensing boiler (complete system consisting of Logano
G225 with fitted oil condensing heat exchanger)
The operations to be carried out for assembly
and installation are identical for the Logano
G225 and the Logano plus GB225 and are
described in these instructions for the
Logano G225.
The differing dimensions, technical
specifications and wall clearances, and the
additional operations for commissioning,
maintenance and servicing of the Logano
plus GB225 can be found in the enclosed
supplement.
The Logano G225 fan-assisted, low temperature boiler
and the Logano plus GB225 fan-assisted, low
temperature condensing boiler are generally referred to in
the remainder of this document simply as the boiler.
These installation and servicing instructions are intended
for qualified heating contractors, who – as a result of their
technical training and experience – are skilled in dealing
with heating systems and oil installations.

Notes on installation and operation

When installing and operating the heating system
observe the following:
– Local building regulations regarding the installation
conditions
– Local building regulations regarding air supply and
venting systems and the chimney flue connection
– Regulations governing electrical connection to the
mains power supply
– Regulations and standards relating to the safety
systems for the central heating system
– Remember that regional approvals may be required for
the flue system and connecting the condensate outlet
to the public sewer system.
2.5

Heating system water quality

As pure water cannot be used for heat transfer, water
quality is important. Poor water quality can damage
heating systems due to scale formation and corrosion.
Caution: Risk of system damage due to
unsuitable heating system water.
V If oxygen-permeable pipes are used, e.g.
for underfloor heating systems, the
systems must be separated from one
another by heat exchangers. Unsuitable
heating system water promotes sludge
and corrosion formation. That may result in
heat exchanger malfunction and damage.
2.6

Tools, materials and equipment

For the installation and maintenance of the boiler, you will
need the standard tools used for central heating, gas and
water systems plus set of a metric open-ended spanners
and Allen keys.
The following may also prove useful:
– Sack truck with securing strap or Buderus boiler trolley
– Timber supports
– Cleaning brushes and/or chemical cleaning agent for
wet cleaning
