MAINTENANCE TECHNICIAN
NOYES
In the event of malfunctions, faults or incorrect
operation, turn the appliance o and contact an
authorised company (e.g. the Authorised Tech-
nical Assistance centre, which has specically
trained sta 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 Standards:
- installation of gas appliances, ue 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 the cooking surface.
- Installation is forbidden in places/rooms
that constitute public areas of apartment
buildings, internal stairways or other escape
routes (e.g. oor landings, entrance halls,
etc.).
- Installation is also forbidden in places/rooms
that constitute public areas of apartment
buildings such as cellars, entrance halls, attics,
los, etc., unless otherwise provided for by
local regulations in force.
Attention: wall mounting of the boiler must
guarantee stable and ecient support for the
generator.
e plugs (standard supply) are to be used only in
conjunction with the mounting brackets or xing
template to x 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
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 mount.
Note: the hex head screws supplied in the
blister pack are to be used exclusively to x the
relative mounting bracket to the wall.
ese boilers are used to heat water to below
boiling temperature in atmospheric pressure.
ey must be connected to a central heating
system and domestic hot water circuit suited to
their performance and capacity.
1BOILER INSTALLATION.
1.1 INSTALLATION
RECOMMENDATIONS.
e Eolo Mythos Dom 10-18-24 1E boiler has
been designed for wall mounted installation only,
for heating and production of domestic hot water
for domestic use and similar purposes.
e place of installation of the appliance and
relative Immergas accessories must have suitable
features (technical and structural), such as to al-
low for (always in safe, ecient and comfortable
conditions):
- installation (according to the provisions of
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 com-
ponents) as well as the eventual replacement
of those with appliances and/or equivalent
components.
e wall surface must be smooth, without any
protrusions or recesses enabling access to the
rear part. ey are not designed to be installed
on plinths or oors (Fig. 1-1).
By varying the type of installation the classicati-
on of the boiler also varies, precisely:
- Type B22 boiler if installed using the relevant
terminal for air intake directly from the room
in which the boiler has been installed.
- Type C boiler if installed using concentric pipes
or other types of pipes envisioned for the sealed
chamber boiler for intake of air and expulsion
of fumes.
Only professionally enabled companies are
authorised to install Immergas gas appliances.
Attention: the manufacturer declines all liability
for damages caused by boilers removed from
other systems or for any non-conformities of
such equipment.
Installation must be carried out according to
regulation standards, current legislation and in
compliance with local technical regulations and
the required technical procedures.
Before installing the appliance, ensure that it
is delivered in perfect condition; if in doubt,
contact the supplier immediately. Packing ma-
terials (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 su-
cient space for normal servicing; it is therefore
recommended to leave at least 45 cm between
the upper part of the boiler and the ceiling and
a gap of 3 cm between the boiler casing and the
vertical sides of the cabinet. Keep all ammable
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; otherwise, the manufac-
turer 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.
