3.1 General
DTG(E)130 - 35/45/65/90/115 Eco.NOxPlus 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, ...).

3.3 Homologations
3.3.1 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.

3. Description
3.8 Hydraulic specifications
Depending on the flow, the following diagrams represent:
- the manometric heights of the heating circulator pumps (delivered
from the factory for DTGE130-35 or, optionally, for DTG130-45,
DTG130-65,DTG130-90 and DTG130-115)
- 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.
ALPHA 2 L 25-60 electronic heating pump (Pump class A):
- Delivered as standard for DTGE130-35 - Optional for DTG130-45 (Package HC142).

CMaximum proportional pressure The pump's operating point can be moved on the maximum proportional pressure curve according to the
heating requirement.
If the heating requirement increases, the pressure increases.
DMinimum proportional pressure The pump's operating point can be moved on the minimum proportional pressure curve according to the
heating requirement.
If the heating requirement increases, the pressure increases.
EMaximum constant pressure The pump's operating point can be moved on the maximum constant pressure curve according to the heating
requirement.
The pressure remains constant, regardless of the heating requirement.
FMinimum constant pressure The pump's operating point can be moved on the minimum constant pressure curve according to the heating
requirement.
The pressure remains constant, regardless of the heating requirement.
GBoiler pressure drop
III Speed III The pump runs at a constant speed and therefore according to a constant curve.
The pump is set to run according to the maximum curve.
The pump can be quickly vented by selecting speed III for a short period.
II Speed II The pump runs at a constant speed and therefore according to a constant curve.
The pump is set to run according to the average curve.
ISpeed I The pump runs at a constant speed and therefore according to a constant curve.
The pump is set to run according to the minimum curve.
