APPLIANCE DESCRIPTION
N ECO BOILER DESCRIPTION
The
N eco series boilers
are oil appliances, that are certified in accordance with European standards
(EN15034). They also bear the Belgian label “OPTIMAZ” (oil boiler).
The
N eco series
are single-circuit (heating) boilers providing a heating output range from 25 to 43 kW.
Three different models are available:
•
N1 eco model (provided with BMV3 burner)
maximum output: 25 kW.
•
N2 eco model (provided with BMV4 burner)
maximum output: 30 kW.
•
N3 eco model (provided with BMV5 burner)
maximum output: 43 kW.
The
N eco boilers
can be directly connected to the flue pipe, using a B23-type connection
Easy control, guaranteed safety
- The heating circuit water temperature is adjusted through the control
thermostat, whose bulb is located next to the outlet section of the boiler. A manual reset safety thermo-
stat stops the burner if the primary circuit fluid temperature reaches 103°C. A minimum thermostat, fitted
at the rear of the boiler and preset at 45°C, delays the heating pump activation. This prevents the risks of
corrosion of the combustion chamber.
Production of domestic hot water
- The
N eco boilers
can be combined with any ACV hot water production
tank.
Operation of the heating pump
The heating pump is controlled by the minimum thermostat fitted at the back of the boiler. It is preset at
45°C, which delays the operation of the heating pump at burner start up and protects the combustion
chamber against corrosion.
Gauge pressure of the heating system
The installation must be fitted with a safety valve set at 3 bar.
Make sure that the system water is always under pressure. When the system is cold and the air has been
bled, the pressure gauge must indicate a pressure between 1 and 1.5 bar depending on the building
height.
