INSTALLATION
OF THE BOILER
1.1 INSTALLATION
RECOMMENDATIONS.
Only professionally qualified heating/plumbing
technicians are authorised to install Immergas
gas appliances.
The “Victrix 115 1 I” range boilers can be in-
stalled outdoors or in a suitable place (heating
control unit).
The installation must respond to the provisions
of the regulations and all laws and Standards in
force that are applicable.
Important:
these boilers are designed exclusively
for wall installation.
These boilers must be used for heating rooms
and similar.
These boilers are used to heat water to a tempe-
rature lower that boiling point at atmospheric
pressure. Therefore, they must be connected to
a heating plant that is suitable for their perfor-
mance and their power.
Before installing the appliance, ensure that it is
delivered in perfect condition; if in doubt, contact
the supplier immediately.
Packaging materials (staples, nails, plastic bags,
polystyrene foam, etc.) constitute a potential
hazard and must be kept out of the reach of
children.
Keep all flammable objects away from the ap-
pliance (paper, rags, plastic, polystyrene, etc.).
In the event of malfunctions, faults or incorrect
operation, turn the appliance off immediately and
contact a qualified technician (e.g. the Immergas
After-Sales Assistance centre, which has specifi-
cally trained staff and original spare parts).
Do not attempt to modify or repair the appliance
alone.
Failure to comply with the above implies personal
responsibility and invalidates the warranty.
• Installation regulations: these boilers have
not been designed to be installed on plinths
or floors (Fig. 1-1), but for wall installation.
The wall surface must be smooth, without any
protrusions or recesses enabling access to the
rear part. Wall mounting of the boiler must
guarantee stable and efficient support for the
generator.
The plugs (standard supply) are to
be used only in conjunction with the mounting
brackets or fixing template to fix the appliance to
the wall
; they only ensure adequate support if
inserted correctly (according to technical stan-
dards) in walls made of solid or semi-hollow
brick or block. In the case of walls made from
hollow brick or block, partitions with limited
static properties, or in any case walls other than
those indicated, a static test must be carried out
to ensure adequate support. The boilers must
be installed in a way to prevent collisions and
tampering.
N.B.: the hex head screws supplied in the blister
pack are to be used exclusively to fix the relative
mounting bracket to the wall.
1.2 POSITION OF THE APPLIANCES.
The “Victrix 115 1 I” range boilers can be in-
stalled:
- outdoors;
- in outdoor places, also adjoining the building
served, located in a covered space, as long a
structurally separated and without walls in
common, or situated on the flat 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.
These places must be destined exclusively for
heating plants.
Important:
the installation of appliances po-
wered 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 an individual appliance
: the mini-
mum height of the room must be 2 m.
Installation of several appliances in cascade (2 or
3 Victrix 115 1 I):
considering the dimensions
of the boiler, the flue collector (to install with
gradient of 3%) and hydraulic manifolds, the
minimum height of the room must be 2.30 m.
The above-mentioned heights allow the correct
installation of the appliances.
Position of the appliances in the room.
Individual appliance
: the distances between any
external point of the boiler and the vertical, hori-
zontal walls of the room must allow accessibility
to the regulation, safety and control elements for
routine maintenance.
Several appliances, not connected to each other, 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
Installation in cascade (2 or 3 Victrix 115 1 I):
see
the indications supplied in par. 1.13.
1.3 AERATION AND VENTILATION OF
THE INSTALLATION ROOMS.
The rooms must have one or more permanent
openings for aeration on external walls. The
openings used for aeration can be protected using
metal grills, meshes and/or rain-proof fins as long
as the net aeration surface is not reduced.
The 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.
Aeration for installation in outdoor places.
The
minimum free surfaces, depending on the total
heating capacity, must not be below (the values
are rounded for excess):
a) places out of the ground (S≥Qx10).
S > 928 cm
2
for N° 1 Victrix 115 1 I individual
S > 1856 cm
2
for N° 2 Victrix 115 1 I in cascade
S > 2784 cm
2
for N° 3 Victrix 115 1 I in cascade
b) basements and underground rooms up to a height
of - 5 m from the reference surface (S≥Qx15).
S > 1392 cm
2
for N° 1 Victrix 115 1 I individual
S > 2784 cm
2
for N° 2 Victrix 115 1 I in cascade
S > 4176 cm
2
for N° 3 Victrix 115 1 I in cascade
c) underground rooms at quota between -5 m and -10 m
from the reference surface (S≥Qx20, min. 5000 cm
2
).
S > 5000 cm
2
for N° 1 Victrix 115 1 I individual
S > 5000 cm
2
for N° 2 Victrix 115 1 I in cascade
S > 5568 cm
2
for N° 3 Victrix 115 1 I in cascade.
In all cases each opening must not have a net
surface area less than 100 cm
2
.
Important:
in the case of installation of applian-
ces powered with gas with greater density than
0.8 (L.P.G.) in outdoor places, out of the ground.
at least 2/3 of the aeration surface must be rea-
lised flush with the walkway, with a minimum
height of 0.2 m.
The 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.
The 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..
Discharge of combustion products.
The “Victrix 115 1 I” boiler must be connected to
an individual flue with safe efficiency.
N.B.:
in the case of individual installation, “Victrix
115 1 I” can be coupled to the System for Ø 80 mm
flexible piping for condensing boilers (par. 1.12).
As an alternative, the “Victrix 115 1 I” boiler
can discharge combustion products directly to
the outside, using the relevant flue exhaust kit
described in this book (par. 1.10 and 1.11).
If the “Victrix 115 1 I” boilers are installed in cascade,
the fume manifold (supplied by Immergas) will be
connected to a correctly dimensioned and efficient
chimney (par. 1.13).
