1.10 VENTILATION OF THE ROOMS.
In the room in which the boiler is installed it is
necessary that at least as much air flows as that
requested for by normal combustion of the gas
and ventilation of the room. Natural air flow must
take place directly through:
- permanent holes in the walls of the room to
ventilate that go towards the outside;
- ventilation pipes, individual or branched type.
The air used for ventilation must be withdrawn
directly from outside, in an area away from sourc-
es of pollution. Natural air flow is also allowed
indirectly by air intake from adjoining rooms. For
further information relative to ventilation of the
rooms follow that envisioned in the regulation.
Evacuation of foul air.
In the rooms where the
gas appliances are installed it may also be neces-
sary, as well as the intake of combustion agent air,
to evacuate foul air, with consequent intake of a
further equal amount of clean air. This must be
realised respecting the provisions of the technical
regulations in force.
1.11 EVACUATION OF COMBUSTION
PRODUCTS: FLUE DUCT AND
BRANCHED MULTIPLE FLUES
The European regulation 813/2013 provides that
this boiler can be installed only to replace simi-
lar equipment connected to existing branched
multiple flues.
Connection to branched multiple flues.
Fitting the appliances to a branched multiple flues
takes place by means of flue ducts.
In the event of fittings with pre-existing flues,
these must be in safe and efficient status and per-
fectly clean because the detachment of any waste
from the walls during functioning, could block
the passage of flue gases, thus causing extremely
dangerous situations for the user.
The flue ducts must be connected to the chimney
or flue in the same room in which the appliance
is installed or, at most, in the adjoining room and
must comply with the requirements indicated by
the current technical regulations.
1.12 FLUE EXHAUST CONTROL DEVICE.
Important:
it is prohibited to put the fumes
exhaust control device out of order voluntarily.
Every piece of this device must be replaced using
original spare parts if they have deteriorated. In
the case of repeated interventions of the fumes
exhaust control device, check the fumes exhaust
flue and the ventilation of the room in which the
boiler is located .
1.13 SYSTEM FILLING.
Once the boiler is connected, proceed with sys-
tem filling via the filling valve (Fig. 2-2).
Filling is performed at low speed to ensure
release of air bubbles in the water via the boiler
and heating system vents.
The boiler has a built-in automatic venting valve
on the circulator. Check if the cap is loose . Open
the radiator air vent valves.
Close vent valves only when water is delivered.
Close the filling valve when the boiler pressure
gauge indicates approx. 1.2 bar.
N.B. : During these operations, turn on the cir-
culating pump at intervals by means of the main
selector switch on the control panel.
1.14 GAS SYSTEM START-UP.
To start up the system, make reference to the
Standard.
In particular, for new gas systems:
- open windows and doors;
- avoid presence of sparks or naked flames;
- bleed all air from pipelines;
- check that the internal system is properly sealed
according to specifications.
1.15 START-UP OF THE BOILER
(IGNITION).
To commission the boiler (the operations listed
below must only be performed by a qualified firm
and without any unauthorised persons):
- check that the internal system is properly sealed
according to the specifications set forth by
technical regulations in force;
- ensure that the type of gas used corresponds to
boiler settings;
- check that there are external factors that may
cause the formation of fuel pockets;
- switch on the boiler and ensure correct ignition;
- make sure that the gas flow rate and relevant
pressure values comply with those given in the
manual (Par. 3-16);
- check the correct ventilation of the rooms;
- check the existing draught during normal
functioning of the appliance, e.g. a draught
gauge positioned at the exit of the appliance
combustion products;
- check that there is no backflow of combustion
products into the room, even during function-
ing of fans;
- ensure that the safety device is engaged in the
event of gas supply failure and check activation
time;
- check activation of the main circuit-breaker
selector upstream from the boiler and on the
unit.
The boiler must not be started up in the event of
failure to comply with any of the above.
1.16 DOMESTIC HOT WATER BOILER
DEVICE.
The Avio 24 2 ERP boiler is the accumulation
type with a capacity of 45 litres. It contains a large
coiled stainless steel heat exchanger pipe, which
allows to notably reduce hot water production
times. These boilers built with stainless steel
casing and bottoms, guarantee long duration.
The assembly concepts and welding (T.I.G.) are
implemented to the minimum detail to ensure
maximum reliability.
The lower inspection flange ensures practical
control of the boiler and the coiled heat ex-
changer and easy internal cleaning.
The domestic water attachments are found on the
flange cover (cold inlet and hot outlet) and also
the magnesium anode holder cap, including the
latter, supplied as standard for internal protection
of the boiler from possible corrosion.
N.B.: every year a skilled technician (e.g. Authori-
sed After-sales Service), must check the efficiency
of the boiler’s Magnesium Anode. The boiler is
prepared for introduction of the domestic water
re-circulation connection.
