INSTALLATION

3 1 Installation standards

The installation must be carried out by qualified personnel,
in compliance with the following reference standards:
- UNI-CIG 7129
- UNI-CIG 7131
- UNI 11071
- CEI 64-8
Always comply with local standards of the Fire Department,
the Gas Company and with possible municipal disposi-
tions.
Positioning
The POWER X are wall-mounted boilers that can be in-
stalled:
- outdoors, in partially protected locations (single boil-
er application), or rather places in which the boiler is
not exposed to direct contact or infiltrations of rain,
snow or hail. The boiler can operate in a temperature
range from -15°C to +60°C. For details please refer to
the "Frost protection" section. All the optional kits that
can be connected to the boiler must be protected on
the basis of their electric protection level.
- in outdoor locations, even adjacent to the relative
building, positioned in uncovered areas, provided
that they are structurally separate and to not have any
common walls, or else on the flat roof of the relative
building, again without any common walls;
- in buildings intended for other uses, or in rooms in-
cluded within the volume of the relative building.
These rooms must be exclusively reserved for the
heating systems.

WARNING
The installation of appliances powered by gas with a den-
sity greater than 0,8 (L.P.G.) is only permitted in above-
ground rooms, even adjoining other above-ground rooms.
In both cases the walking surface must not have any de-
pressions or sunken areas, as these could create potential-
ly hazardous pockets of gas.
There are two categories, based on the type of installation:
1 Type B23P-B53P boilers (forced open installation), with
discharge pipe and combustion air extraction from the
installation area. If the boiler is not installed outdoors,
air intake in the installation area is compulsory.
2 Type C13, C13x; C23; C33, C33x; C43, C43x; C53,
C53x; C63, C63x; C83, C83x; C93, C93x boiler: appli-
ance with airtight chamber, with flue gas discharge pipe
and pick-up of combustion air from outside. It does not
require an air intake point in the installation area. This
type MUST be installed using concentric pipes, or other
types of discharge designed for condensation boilers
with an airtight chamber.
Minimum distances
The distances between any external points of the boiler
and the vertical and horizontal walls of the room must allow
for access to the adjustment, safety, and control devices,
as well as ordinary maintenance operations.
In order to ensure the proper positioning of the appliance,
the following points must also be taken into consideration:
- - it must not be placed above a cooker or other cook-
ing device
- - it is forbidden to leave inflammable products in the
room where the boiler is installed
- any heat-sensitive walls (e.g. wooden walls) must be
protected with proper insulation.
Aeration and Ventilation of the installation areas
The installation areas must have one or more permanent
ventilation openings on the exterior walls. The ventilation
openings may be protected using metal grates, mesh and/
or rain covers, provided that the net area of the ventilation
opening is not compromised.
The ventilation openings must be created and positioned in
such a way as to prevent the formation of pockets of gas,
independently of the cover's shape.
Ventilation for installation in outdoor areas
Based on the overall heat input, the minimum free surface
areas must not be less than the following:
1 above-ground rooms (S ≥ Q x 10)
- S ≥ 470 cm for 1 POWER X single unit
2
- S ≥ 940 cm for 2 POWER X units in cascade
2
- S ≥ 1410 cm for 3 POWER X units in cascade
2
- S ≥ 1880 cm for 4 POWER X units in cascade
2
2 underground and semi-underground rooms down to a
depth of -5 m from the reference floor (S ≥ Q x 15)
- S ≥ 705 cm for 1 POWER X single unit
2
- S ≥ 1410 cm for 2 POWER X units in cascade
2
- S ≥ 2115 cm for 3 POWER X units in cascade
2
- S ≥ 2820 cm for 4 POWER X units in cascade
2
3 underground rooms at depths ranging from -5 m to -10
m from the reference floor
- S > 5000 cm for all configurations
2
In each case, every opening must have a net area of at
least 100 cm .

b
When installing appliances powered by gas with a
density greater than 0.8 (L.P.G.) in above-ground
outdoor areas, at least 2/3 of the ventilation surface
area must be flush with the walking surface, with a
minimum height of 0.2 m. For heat inputs up to 116
kW and heat inputs greater than 116 kW, the ventila-
tion openings must be respectively at least 2 m and
4.5 m away from any sunken areas, depressions, or
openings adjoining other rooms positioned below the
walking surface, or from any drain pipes.
Ventilation for installation in buildings intended for oth-
er uses, or in rooms included within the volume of the
relative building
The ventilation area must not be less than 3000 cm
case of natural gas, and must not be less than 5000 cm
the case of L.P.G.
Refer to the Italian Ministerial Decree of 12 April 1996 for
further indications.
IMPORTANT
Before installation, wash every system piping carefully in
order to remove any residues that may impair the operation
of the appliance.
Under the safety valve, install a water collecting funnel with
a relative drain in the event of any leaks due to excessive
heating system pressure
Prior to ignition, make sure that the boiler is designed to
operate with the gas available; this can be checked by
the wording on the packaging and by the adhesive label
indicating the gas type.
It is very important to highlight that in some cases the
smoke pipes are under pressure, so the joints of the various
elements must be airtight.
