2.3 Homologations
2.3.1 General instructions
Installation must be carried out in accordance with the prevailing
regulations, the codes of practice and the recommendations in these
instructions.
The first start-up is to be performed by your installation/
commissioning engineer.
Only original spare parts must be used.
Any work on the gas valve unit is authorised only if carried out by a
qualified professional. Please confirm to the user of the installation
that you have carried out a leak tightness check on the gas circuit.
In application of Article 25 of the Order of 27 April 2009 amending the
Order of 2 August 1977 amended and Article 1 of the amended Order
of 05/02/1999, the installer is required to draw up certificates of
conformity approved by the Ministers responsible for construction
and gas safety. Boilers must be used only with the types of gas
indicated on the rating plate.
Before commissioning, the factory settings of the appliance must be
compared with the local energy supply conditions. If the settings have
to be modified, this must be carried out by a qualified professional.
Condensing boilers require a flue gas discharge system or a fresh air
inlet specially adapted to the method of operation. Its execution
depends on the place of installation and the building.
Compliance with a minimum distance between the flue gas discharge
system in forced flue mode or the boiler with combustible substances
is not necessary. At nominal output, the temperature of the
components does not exceed 85 °C.
Work on electrical equipment must be carried out by a
qualified professional in compliance with the prevailing
regulations.
Switzerland
SVGW No.: 08-008-4
The installation of the boiler must be done in compliance with the
following directives:
- SSIGE regulations - G1: Gas installation,
- VKF requirements (Cantonal Grouping of Insurance Brokers),
- Local and cantonal regulations.
Installation and maintenance of the boiler must be carried out by a
qualified professional in compliance with prevailing local and national
regulations.
The safety distance between combustible substances and the boiler
and gaseous effluents must comply with the requirements of the
AEAI standard.
Other countries
Installation and maintenance of the boiler must be carried out by a
qualified professional in compliance with prevailing local and national
regulations.
Belgium
The appliances comply with the requirements and standards laid
down in the Royal Decree of 8 January 2004 and in the 17 July 2009.
Installation and maintenance of the boiler must be carried out by a
qualified professional in compliance with prevailing local and national
regulations.
The boiler is preset in the factory to operate on natural gas G20.
It is formally prohibited to interfere with the gas block.

3.1 General
DTG130 - 45/65/90/115 Eco.NOx Plus boiler are floor-standing gas-
fired condensing boilers fitted with a DIEMATIC3 conversational
control unit. They handle central heating and the production of
domestic hot water (when DHW tank is connected).
They are designed for closed circuit hot water boiler rooms with a
maximum operating temperature of 90°C. Their installation is
recommended on low temperature heating installations (underfloor
heating, gentle heat radiators, etc.).

Depending on the flow, the following diagrams represent:
- the manometric heights of the heating circulator pumps (Option),
- loss of load in the boiler.
For a fixed flow, the manometric height available at the boiler outlet
is obtained by taking the difference between the manometric height
of the circulator pump and the loss of load in the boiler.
