FASTECH KI: If the fumes thermostat trips repeatedly, this
means combustion products are evacuated towards the boiler
installation area. This means combustion may be incomplete
and there is a risk of carbon monoxide forming. This is a serious
hazard. In this case, please contact the Technical Assistance
Service immediately.
The boiler must not be operated, even temporarily, if the safety
devices are not functioning or have been tampered with.
The safety devices must be replaced by the Technical Assistance
Service, using original manufacturer components only. Please
see the spare parts catalogue supplied with the boiler.
After repairs, always perform an ignition test.
3 - INSTALLATION
FASTECH KI: In existing buildings, this natural draught boiler
must only be connected to a flue system shared by several
homes to evacuate the combustion residue outside the room
where the boiler is installed. For combustion, the boiler takes
in air directly from the room and is equipped with a draught
diverter. Due to reduced efficiency, any other use of this boiler
must be avoided at all times, as this would lead to increased
energy consumption and higher operation costs.
3.1 Product delivery
The FASTECH boiler is supplied in a single box protected by carton
packaging.
The boiler is supplied with the following material:
- installer and user manual
- labels with bar code
- screws and plugs
- flange ø 42 (only KIS models).
The instruction manuals are an integral part of the boiler. Please
read the manuals and store them in a safe place.
3.2 Dimensions and weight (fig. 1)

Net weight 30 28 kg
3.3 Handling
After removing all packaging, the boiler is handled manually using the
support frame (fig. 2).
3.4 Installation room
FASTECH KI
The boiler must be installed in rooms fitted with suitably sized
ventilation outlets compliant with current technical standards.
FASTECH KIS
In configuration C, the appliance can be installed in any type of room
and there are no limitations due to ventilation conditions or room
volume since the boiler has an “airtight” combustion circuit in relation
to the installation environment.
In configuration B22P and B52P the appliance cannot be installed in
bedrooms, bathrooms, showers or where there are open fireplaces
without a proper air flow. The room where the boiler is installed must
have proper ventilation.
Take into consideration the space that is required to access the
safety and control devices and to perform maintenance.
Check that the appliance's electrical protection rating is suitable
for the place of installation.
If the boiler is run on combustible gas of a specific weight
greater than that of air, the electrical parts must be positioned
at a minimum height of 500 mm from the ground.
FASTECH KI: The boiler cannot be installed outside as it is not
designed for operation outdoors.
3.5 Installation in older systems or circuits requiring
renovation
When FASTECH boilers are installed in older systems or systems
requiring renovation, ensure that:
- the flue exhaust is suitable for the temperatures produced by
combustion, calculated and built in line with the regulations, and is as
straight as possible, airtight, insulated and not blocked or constricted
- the electrical system complies with the specific regulations and is
installed by qualified technicians
- the gas conveyance line and any tanks (LPG) comply with specific
regulations
- the expansion tank ensures full absorption of the expansion of the
fluid in the system
- the flow rate and useful head of the pump are suitable for the system
- the system is washed, free of all dirt and build-up, de-aerated and
correctly sealed
- there is a treatment system when the supply/top-up water is of a
specific type (see the table for possible reference values).
Supply water values
pH 6-8
Electrical conductivity less than 200 μS/cm (25°C)
Chloride ions less than 50 ppm
Sulphuric acid ions less than 50 ppm
Total iron less than 0.3 ppm
Alkalinity M less than 50 ppm
Total hardness less than 35°F
Sulphur ions None
Ammonia ions None
Silicon ions less than 20 ppm
The manufacturer declines all liability for possible damage
caused by incorrect installation of the flue outlet system.
If the supply water has a total hardness of between 25°F and
50°F, install the domestic water kit (polyphosphate dispenser). If
the total hardness is above 50°F, the kit progressively decreases
in efficiency and a higher performing appliance or a water
softening system should be installed. In case of total hardness
below 25°F, a suitably sized filter should be installed if the water
supplied form the mains is not perfectly clean/cannot be cleaned.
3.6 Boiler installation
To install the boiler correctly, please remember that:
- the boiler must not be installed above a stove or other cooking
equipment
- flammable substances must not be left in the room where the boiler
is installed
- walls sensitive to heat (for example those in wood) must be protected
with suitable insulation
- minimum clearances must be observed to enable technical
interventions and maintenance.
FASTECH KI
Installation must be carried out by qualified personnel, in accordance
with the regulations in law. In particular UNI 7129-7131 and CEI 64-8
and 64-9 must be respected.
FASTECH KIS (fig. 3a)
The boiler can be installed indoor and outdoor.
Indoor installation: it may be installed in numerous rooms as long
as the combustion product outlet and combustion air suction are
brought outside the room itself. In this case, the room does not require
any ventilation opening because these are boilers with an “airtight”
combustion circuit in relation to the installation environment.
If, instead, the combustion air is picked up from the installation room,
the latter must be equipped with ventilation openings compliant with
Technical Standards and suitably dimensioned.
Consider the clearances necessary to access safety and adjustment
devices and to perform maintenance operations.
Check that the electric protection level of the appliance is adapted to
the installation room characteristics.
In case the boilers are supplied with fuel gas of a specific weight greater
than that of the air, the electric parts will have to be placed at a level
above the ground greater than 500 mm.
