1. INTRODUCTION
The global trend, European and international, aims at improving energy efficiency both in buildings and generators,
in order to reduce pollutant emissions in the atmosphere (SAVE directive, KYOTO agreement).
Carbon dioxide (CO 2 ) is one of the greenhouse gases that remain the longest in the atmosphere. In accordance
with IEO2007, predicted CO 2 emissions will be 33.9 billon tons in 2015 and 42.9 in 2030.
This is why the European campaign known as “20-20-20 in 2020” has been created, with the aim, among others, of
cutting carbon dioxide emissions by 20% by 2020.
ADISA HEATING, BY HITECSA, company specialized in the manufacturing of gas boilers with high efficiency
performances and reduced pollutant emissions (“clean combustion”), has developed an innovating and
revolutionary product contributing to a technological evolution in the field of water boilers for centralized
installations: the ADI CD boiler.
The main characteristics of the ADI CD 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 CERTIGAZ, high energy efficiency (according to the European directive 92/42/EEC).
-Seasonal Efficiency up to 108% ref. to L.C.V.
-Boiler agrees with the ErP (Energy related Products) Ecodesign Directive.
-Boiler certified as “Low temperature”: flow temperature up to 90ºC, no limit of return temperature.
-Boiler heat exchanger in stainless steel.
-Power outputs from 70,4 to 904 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 23% 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).
NOx: about 10 ppm, CO: about 50 ppm (both referred to 3% O
2
).
-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.
-Reduced dimensions and weight:
Boiler heat exchanger ADI CD 450 (440 kW of output) Large: 81 cm, Long: 94 cm, Weight: 460 kg.
Easy installation in boilers rooms of difficult access.
Installation in terraces (reinforcement of the structure is not required).
Space saving in boilers rooms (440 kW in less than 0.76 m
2
).

2. REGULATIONS
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.

7. BOILER HEAT EXCHANGER
The boiler heat exchanger (flues-water) is made of stainless steel: it is a
stainless steel enriched with a special alloy (for a better resistance to
corrosion and to high temperatures).
The boiler heat exchanger consists of 2 water collectors, an upper one and
a lower one, connected by means of multiple vertical tubes forming the
combustion chamber. The vertical tubes generate a big heat transfer
surface that uses the sensible heat of the flues.
During the manufacturing process, the boiler is subjected to a strict quality
control, through a process of three leak tests: one with penetrant liquids,
another one with air pressure and the last one with water pressure.
The boiler heat exchanger is insulated.
Several manual air ventss are installed in the higher part of the boiler for
the air venting of the boiler.
Front and rear view: models ADI CD 175 and lower Front and rear view: models ADI CD 200 and hi her
Without rear plate, casin non insulated.

8.1 Assembly of gas connection – air/gas inlet

15
Pa
5
13 Pg
1 0
V. 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 (G) towards the gas valve outlet (VV).
It operates as an additional safety: if there is no air inlet, there will be no gas admission.
VV. The gas shut-off valve regulates the gas outlet pressure according to the pressure value in the
venturi.
Note: (13) in models CD 200 and higher: a coupling pipe between the gas shut-off valve and the venturi
measures the pressure drop before the mix. For lower models there is no pipe, the connection between
the gas shut-off valve and the venturi is internal.
M. The power modulation is made by varying the fan speed, which also produces a variation of
the air-gas mix flow entering into the burner (B).
Pg. Minimum inlet pressure switch: adjusted at 15 mbar.
For all models: when installing a boiler, install before the gas connection, a gas filter, accessible and
ajustable / cleanable, to retain waste / dust / welding in the gas pipe and prevent its entry into the boiler.
In models ADI CD 70 to 250 : these pieces form one only
global group: burner, burner-holder plate, motor-fan, venturi
and gas shut-off valve.

8.2 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 photo.
Only included in models CD 200 and higher.
9. BURNER
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 vertically
introduced in the boiler.
The boiler incorporates an ionization flame control. The minimum ionization value must always be superior to
5 microamperes.
9.1 Ignition and ionization kit
The ignition is electronic by means of an electric transformer that
produces a train of sparks on the ignition electrode (3), with the
special feature that the sparks fly from the electrode to the mass
included in this electrode, and not on the burner.
The safety of flame presence is checked by means of an ionization
electrode (2).
The minimum ionization value must be always higher than 5
microamperes.
Flame may be checked by means of a glass spy (4).
