Notes on installation and operation

When installing and operating the heating system observe the following:
• The local building regulations regarding the installation conditions.
• The local building regulations regarding ventilation air and extract air
facilities, and the chimney connection.
• Electrical code requirements for connection to the power supply.
• The technical regulations of the gas company regarding the
connection of the gas burner to the local main gas supply.
• The regulations and standards relating to the safety of DHW heating
system.

2.4.1 Other important information

• The installation of a boiler must be notified to and approved by the
relevant gas utility company.
• Only operate the boiler with the combined air/flue system specifically
designed and approved for it.
• Remember that regional approvals are required for the flue system
and connecting the condensate outlet to the public sewer system.
If a high limit safety cut-out is installed according to
ASME-CSD1 on the flow piece of the (B-kit), heed the
following:
▶ At the plant, a pump post purge time of 5 minutes is
set on the BC10 controls. This value can be increased
but not reduced.
▶ If an external controller controls the recirculation
pump, a pump post purge time of 5 minutes must be
ensured.

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. For further details, please see the
accompanying "Water quality requirements for Logano plus
GB312" manual.
CAUTION: Risk of system damage due to unsuitable
heating system water.
▶ When using oxygen-permeable pipes, e. g. for radiant
floor heating systems, you must separate the system
using heat exchangers. Unsuitable heating system
water promotes sludge and corrosion formation. This
can result in heat exchanger malfunction and damage.
2.6

Tools, materials and equipment

For the installation and maintenance of the boiler, you will require the
standard tools used for central heating and gas and water systems plus
set of a metric wrenches and hex keys.
The following items are also of use:
• The RC35 programming unit is required as a monitoring device for
commissioning, servicing and maintaining the boiler.
A PC with Buderus Logamatic ECO-Soft 4000/EMS and
a service key can also be used as a monitoring device.
• 2 pipes (approx. 1¼ ", approx. 6.6 ft long) for carrying the boiler or 5
pipes (approx. 1¼ ", approx. 28 ins long) for placing underneath the
boiler to act as rollers
• Cleaning blade and/or chemical cleaning agent for wet cleaning
2.7

Disposal
