1.1 INSTALLATION
RECOMMENDATIONS.
The Mini Nike X 24 3 E boiler has been designed
for wall mounted installation only, for heating
environments and production of domestic hot
water (when the boiler is connected to an external
storage tank unit) 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 components) as well as their eventual
replacement with appliances and/or equivalent
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.
Important : the manufacturer 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 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 flue removal
connections. 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 with
an obstructed conveying system (the safety valve
must be 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 malfunctions, faults or incorrect
operation, turn the appliance off immediately
and contact an authorised company (e.g.
the Technical Assistance centre, which has
specifically 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:
- 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 of gas appliances, flue exhaust
pipes and combustion air intake pipes is
forbidden in places with a fire risk (for
example: garages, closed parking stalls), and
in potentially dangerous places.
- 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. floor landings, entrance halls,
etc.).
- 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
harmful for the components of the appliance
and jeopardise operation;
- they must also be installed in rooms where
the temperature cannot fall below 0°C and
must not be exposed to weathering.
