1.4 POSITION OF THE APPLIANCES.
e boilers can be installed:
- outdoors;
- in outdoor environments, also adjoining the building served,
located in uncovered space, as long as structurally separated and
without walls in common, or situated on the at covering of the
building served, always without walls in common;
- in building also destined for other use or in places inserted in
the volume of the building served.
ese rooms must be intended exclusively to house CH systems
and must have characteristics that comply with legislation in force.
ATTENTION:
the installation of appliances powered
with gas with a greater density than 0.8
(L.P.G.) is only allowed in places out of the
ground, also communicating with places that
are on the ground. In both cases the walkway
must not have hollows or depressions such to
create gas pockets that determine dangerous
conditions.
Height of the installation room.
Installation of individual appliance: the room must have a mini-
mum ceiling height of 2 m.
Installation of multiple appliances in cascade (2 ÷ 5 Victrix Pro 2
ErP): considering the size of the boiler, the ue manifold (which
must be installed on a 3% gradient) and the hydraulic manifolds,
the room must have a minimum ceiling height of 2.3 m.
If the installed heat input in the room is between 350 kW and 580
kW, the minimum height of the room must be 2.60 m; the minimum
room height is 2.90 m for heat inputs greater than 580 kW..
e aforementioned heights allow for correct installation of the
appliances and observe the technical regulations in force.
Position of the appliances in the room.
Individual appliance: the distances between any external point of
the boiler and the vertical and horizontal walls of the room must
allow accessibility to the regulation, safety and control elements
for routine maintenance.
Multiple appliances, not interconnected, but installed in the same
room: the minimum distance to maintain between several boilers
installed on the same wall must be 200 mm, in order to allow
accessibility to the regulation, safety and control elements and
routine maintenance of all appliances installed.
Cascade installation (2 ÷ 5 Victrix Pro 2 ErP): e instructions
for correct cascade installation are provided in the respective
documents or on the www.immergas.com website in the high
power section.
1.5 AERATION AND VENTILATION OF THE
INSTALLATION ROOMS.
e rooms must have one or more permanent openings for aer-
ation on external walls. e openings used for aeration can be
protected using metal grills, meshes and/or rain-proof ns as long
as the net aeration surface is not reduced.
e aeration openings must be realised and located in a way to
prevent the formation of pockets of gas, independently from the
conformation of the covering. e resulting total opening may be
split in more openings, in all cases each opening must not have a
net surface less than 100 cm
2
.
Aeration for installation in outdoor places. e minimum free
surfaces, in relation to the overall heat input must not be below:
a) above-ground rooms (S ≥ Q x 10)
S > 755 cm
2
for every Victrix Pro 80 2ErP
S > 925 cm
2
for every Victrix Pro 100 2ErP
S > 1145 cm
2
for every Victrix Pro 120 2ErP
(ex: to install 3 Victrix Pro 80 2ErP in cascade, the minimum
surface is 755 x 3 = 2265 cm
2
)
b) basements and underground rooms up to a height of -5 m from
the reference surface (S ≥ Q x 15).
S > 1130 cm
2
for every Victrix Pro 80 2ErP
S > 1385 cm
2
for every Victrix Pro 100 2ErP
S > 1712 cm
2
for every Victrix Pro 120 2ErP
(ex: to install 3 Victrix Pro 80 2ErP in cascade, the minimum
surface is 1130 x 3 = 3390 cm
2
)
c) underground rooms at quota between -5 m and -10 m from the
reference surface (S ≥ Q x 20 with a minimum of 5000 cm
2
).
S > 5000 cm
2
for all congurations
In all cases each opening must not have a net surface area less
than 100 cm
2
.
ATTENTION:
in the case of installation of appliances
powered with gas with greater density
than 0.8 (L.P.G.) in outdoor places, above-
ground, at least 2/3 of the aeration surface must
be ush with the oor, with a minimum height
of 0.2 m.
e aeration openings must be at least 2 m for
heating capacities not exceeding 116 kW and 4.5
m for higher heating capacities, cavities, depres-
sions or openings communicating with rooms
below the walkway surface or draining ducts.
Aeration for installation in building also destined for other
use or in places inserted in the volume of the building served.
e aeration surface must not be less than 3000 cm
2
in the case of
natural gas and must not be less than 5000 cm
2
in the case of L.P.G..
e installation must comply with the requirements of all relevant
codes and standards.
