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
START 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 START boiler is supplied in a single box protected by carton
packaging.
The boiler is supplied with the following material:
- installer's and user's instructions booklet
- bar code labels
- flange Ø 42 (START 24 KIS)
- flanges Ø 43-47 (START 28 KIS)
The instruction manuals are an integral part of the boiler. Please
read the manuals and store them in a safe place.

Installation room

START KI
boiler must be installed in rooms having aeration openings in
compliance with the Technical Standards and of adequate dimensions.
START 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.
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 suitable
for 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.
3.5 Installation in older systems or circuits requiring
renovation
When START 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
- the boiler condensate drain system (siphon) is connected and routed
to the collection of "white" water (KIS models)
- there is a treatment system when the supply/top-up water is of a
specific type (see the table for possible reference values).

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.

Boiler installation

For a correct installation, keep in mind that:
- the boiler must not be placed above a stove or other cooking
appliance;
- it is forbidden to leave flammable products in the room where the
boiler is installed;
- heat-sensitive walls (e.g. wooden walls) must be protected with
suitable insulation;
- the minimum clearances for technical and maintenance interventions
must be respected.
START 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.
START KIS (fig. 3a)
The boiler can be installed indoor and outdoor.
Indoor installation: they 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.
Outdoor installation: The boiler can be installed outdoor, in a partially
protected place (i.e. a place where the boiler is not exposed to direct
contact or infiltration of rain, snow or hail).
The boiler is fitted as standard with an automatic anti-freeze system
that actives when the water temperature in the primary circuit falls
below 6°C. To take advantage of this protection, based on the burner
operation, the boiler must be able to switch itself on; any lockout
condition (i.e. due to a lack of gas or electrical supply, or the intervention
of a safety device) therefore deactivates the protection.
