1INTRODUCTION
The main characteristics of the NEO FIRE boiler are:
- Maximum efficiency in every kind of installations at any working temperatures.
Renovation of installations with traditional heat radiators
New installations of very Low Temperature (heating floor, fan-coils, A.H.U., etc.)
Domestic Hot Water (D.H.W.), in accordance with anti-legionella regulations.
EEC Approval by SZU, high energy efficiency (according to the European directive 92/42/EEC).
Efficiency up to 108,81% ref. to L.C.V.
Boiler agrees with the ErP (Energy related Products) Ecodesign Directive.
Boiler certified as “Condensing boiler”: flow temperature up to 90ºC, no limit of return temperature.
Aluminium heat exchanger boiler
Power outputs from 78 to 944 kW.
Maximum efficiency per year :
Variable temperature on boiler.
Boiler power modulation according to the demands of the installation.
High reduction of stop/start cycles.
Minimum heat losses due to convection/radiation through the boiler.
Inconsiderable heat losses through the chimney when the boiler is not operating.
Gas boilers with modulating burner starting from 12% of power (depending on the installation conditions
and models).
Burner power modulation by varying the premix air-gas flow by means of a variable speed motor fan.
Reduced electric consumptions per year thanks to a variable speed motor fan for the air-gas inlet.
Ecological combustion (“PREMIX” burner of innovative design).
Boiler regulation and control adaptable to all systems available on the market:
The boiler can operate by means of its own regulation.
It can be connected to a sequence control unit in an installation with several boilers.
It can be connected to Building Management System (B.M.S.).
It can be connected to telecomputing.

WARNINGS AGAINST INCORRET USE
Following points are consideres as incorrect use of the boiler
•Electric supply different from indicated
•Using water out of ranges described in the present manual
•Unauthorized modification of any part or component of the boiler
•No correct air ventilation of the boilers room, or environment with excess of humidity, dust or
aggressive vapours or steams.
•Water refilling to the boilers circuit exceed the maximum volume allowed of refilling water into the
installation
•Use in explosive atmosphere.
•Use the boiler for any other purposes than the ones described in the present manual
2REGULATIONS
The installation must be designed and made by qualified professionals in accordance with the current
regulations referring to gas, air venting, flues evacuation, electricity, safeties, fire prevention, etc.
The boiler maintenance must be made following the instructions of the manufacturer’s technical manual
and with a minimum regularity as indicated by the current regulations.
Following installation of the boiler, the installer shall instruct the user in the operation of the boiler and the
safety devices and shall give at least the user’s instructions to the user.
3EEC APPROVALS AND CERTIFICATIONS
ADISA boilers, NEO FIRE, are certified as follows:
The European Directive of Boilers Efficiency, dir. 92/42/EEC, is only applied to boilers from 4 to 400 kW.
Agrees with the following Regulations and Directives:

- European Directive 92/42/CE efficiency requirements for new hot-water boilers fired with liquid or
gaseous fuels (up to 400 kW)
- standards EN 15502-1 and EN 15502-2-1
- directive 2014/35/EU (LVD)
- Regulatio Commission Ecodesign regulation (ErP: Energy related Products) 813/2013. See more info in
paragraph 19.
- Directive RoHS : 2011/65/UE.

7POWER MODULATION AND COMBUSTION SYSTEM
7.1 Assembly of gas connection –air/gas inlet
The NEO FIRE boiler includes an air-gas premix system of modulating combustion, composed of:
Venturi operating as an air-gas mixer, ensuring combustion with a constant proportion of air/gas to the
premix burner, throughout its power modulation range.
The venturi produces a depression and drives the gas towards the gas valve outlet
It operates as an additional safety: if there is no air inlet, there will be no gas admission.
The gas shut-off valve regulates the gas outlet pressure according to the pressure value in the venturi.

NEO FIRE –Technical Manual
17
7.2 Air inlet filter
The air inlet to the venturi is protected by a filter retaining the dust that is usually in the atmosphere.
Attention: it is important to avoid excessively dusty or dirty environments (for ex. in case of building work in
the same room or in places next to the ventilation ducts of the boilers room) or environments with
aggressive steams (evacuation or air outlet of industrial laundries...).
See an example of the filter in the attached picture.
Only included in models NEO FIRE 360 and higher.
8BURNER
The boiler includes an air-gas premix burner of innovative design and material:
Fire resisting alloy mesh.
Homogeneous and stable combustion in case of any change in the power demand.
High mechanic resistance and high resistance to high temperatures.
Very low thermal inertia fast cooling (for an easier maintenance).
Fast answer to the changes of the power demand.
Thanks to its structure and design, noise produced by the combustion is very low and without resonance.
The cylindrical shape of the burner allows the flame to be homogeneously distributed. It is horizontally
introduced in the boiler.
The boiler incorporates an ionization flame control. The minimum ionization value must always be superior
to 5 microamperes.
