INSTALLATION OF THE
BOILER
1.1 INSTALLATION
RECOMMENDATIONS.
The Avio 24 2 ErP boiler has been designed for
wall mounted installation only, for heating and
production of domestic hot water for domestic
use and similar purposes.
The place of installation of the appliance and
relative Immergas accessories must have suitable
features (technical and structural) such to allow
(always in safety, efficiency and comfortable
conditions):
- installation (according to the provisions of the
technical legislation and technical regulations);
- maintenance operations (including scheduled,
periodic, routine and special maintenance);
- removal (to outdoors in the place for loading
and transporting the appliances and compo-
nents) as well as their possible replacement
with equivalent appliances and/or components.
The wall surface must be smooth, without any
protrusions or recesses enabling access to the
rear part. They are NOT designed to be installed
on plinths or floors (Fig. 1-1).
Only professionally enabled companies are
authorised to install Immergas gas appliances.
Installation must be carried out according to
regulation standards, current legislation and in
compliance with local technical regulations and
the required technical procedures.
Attention
: Immergas declines all liability for
damages caused by boilers removed from other
systems or for any non-conformities of such
equipment.
Before installing the appliance, ensure that it is
delivered in perfect condition; if in doubt, contact
the supplier immediately.
Packing materials (staples, nails, plastic bags,
polystyrene foam, etc.) constitute a hazard and
must be kept out of the reach of children. If the
appliance is installed inside or between cabinets,
ensure sufficient space for normal servicing;
therefore it is advisable to leave a clearance of
at least 3 cm between the boiler casing and the
vertical sides of the cabinet.
Leave adequate space above the boiler for
possible water and fume removal connections.
At least 60 cm must be left below the boiler
in order to guarantee replacement of the
magnesium anode.
It is just as important that the intake grids are
not obstructed.
Keep all flammable objects away from the
appliance(paper, rags, plastic, polystyrene, etc.).
Do not place household appliances underneath
the boiler as they could be damaged if the
safety valve intervenes (if not conveyed away
by a draining funnel), or if there are leaks from
the hydraulic connections; on the contrary, the
manufacturer cannot be held responsible for
any damage caused to the household appliances.
For the aforementioned reasons, we recommend
not placing furnishings, furniture, etc. under
the boiler.
In the event of a malfunction, fault or incorrect
operation, turn the appliance off and contact
an authorised company (e.g. the Authorised
Technical Assistance centre, which has
specifically trained staff and original spare parts).
Do not attempt to modify or repair the ap-
pliance alone. Failure to comply with the above
implies personal responsibility and invalidates
the warranty.
• Installation regulations:
- installation of these boilers in bedrooms,
studio flats and bathrooms, or in premises
where there are wood fired heaters (or by
solid fuels in general) and in premises next
to or connected to them, is subject to the
regulatory/legislative provisions in force in
the country.
- installation in places with a fire risk is
prohibited (for example: underground car
parks, garages), potentially dangerous places,
gas appliances and relative flue ducts.
- installation is prohibited on the vertical
projection of cooking hobs;
- installation is forbidden in places/rooms
that constitute public areas of apartment
buildings, internal stairways or other
escape routes (e.g. landings, entrance halls,
etc.) unless otherwise provided by local
regulations;
- installation is also forbidden in places/rooms
that constitute public areas of apartment
buildings such as cellars, entrance halls, attics,
lofts, etc., unless otherwise provided for by
local regulations in force;
- Type B open chamber boilers must not be
installed in places where commercial, artisan
or industrial activities take place, which use
products that may develop volatile vapours
or substances (e.g. acid vapours, glues, paints,
solvents, combustibles, etc.), as well as dusts
(e.g. dust deriving from the working of wood,
coal fines, cement, etc.), which may be dama-
ging for the components of the appliance and
jeopardise functioning.
- They must also be installed in an environ-
ment in which the temperature cannot fall
below 0°C. They must not be exposed to
atmospheric agents.
- This natural draught boiler can be connected
only to a multiple branched flue served by
a variety of users in existing buildings. The
boiler takes the combustion air directly from
the installation room and is equipped with
draught-breaker/anti-wind device. Due to
lower efficiency, any other use of this boiler
must be avoided as it would lead to greater
consumption and higher operating costs.
Important:
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 standards) in walls made
of solid or semi-hollow brick or block. In the
