Information on installation and operation
Regarding installation and operation of your heating
system, observe all relevant national standards and
guidelines.
The information on the data plate is binding and must be
observed.
3.1
Standards, regulations and directives
Observe all technical guidelines, country-specific regulations and
standards applicable to installation and operation. These include the
following:
• Local building regulations concerning the installation conditions.
• Local building regulations concerning the ventilation facilities and
chimney connection.
• Requirements for the electrical connection to the power supply.
• Technical rules of the gas supplier concerning the connection of the
gas burner to the public gas mains
• Regulations and standards concerning the safety equipment level of
wet heating systems.
The level of safety equipment must be at least compliant with EN
12828. Also observe country-specific regulations if these specify
further requirements.

Duty to obtain a permit and provide notification
• The local gas supply utility might need to be notified of and approve
the gas boiler installation
• Please note that regional approvals may be required for the flue
system and condensate connection to the public sewage system
• Prior to commencing installation, inform the relevant bodies and the
water board.
3.3
Burner selection and settings
The sizing and settings of the burner have a significant influence on the
service life of the heating system. Every load cycle (burner on/off)
causes thermal stress (loads on the boiler body). The number of burner
starts must therefore not exceed 15,000 per year.
The following recommendations and settings are designed to meet this
criterion (see also information on setting the control unit and the
hydraulic connection to the heating system). If you still cannot meet
this criterion, please contact the Bosch sales or service department.
The number of burner starts can be checked in the MEC
(
chapter 3.8, page 10).
• Set the burner output as low as possible. Set the burner to the
combustion heating output QN specified on the data plate as a
maximum. Never overload the boiler.
