3 Instructions for the
fitter
3.1 Installation regulations
NIAS is an II2H3+ class boiler
which must be installed in
compliance with applicable
country standards, laws and
regulations.
3.2 Installation
3.2.1 Packaging
NIAS
is packaged and
delivered in a strong cardboard
box on wooden pallet. Once the
boiler has been unpacked
check the boiler is undamaged.
The packaging material can be
recycled and it must be
disposed of accordingly.
Keep the packaging out of the
reach of children as it may
represent a choking and
suffocation hazard.
FONDITAL cannot be held
liable for injury to persons
and animals or damage to
property resulting from non-
observance of the above.
The packaging contains:
- copper pipe kit for hydraulic
connection of the boiler to
heating system, water system
and gas mains,
- metal template for boiler wall-
hanging and system
connecting,
- installation, use and
maintenance handbook,
- 4 screws with dowels for boiler
wall-hanging,
- for BTFS models only: flue
diaphragm.
3.2.2 Choosing where to
install the boiler
When choosing the position of
the boiler:
- refer to instructions given in
the “Flue system“ section,
- remember that it is advisable
to leave a space of 50 mm on
each side of the boiler to
facilitate maintenance
operations,
- check wall sturdiness,
- avoid fixing the boiler to thin
partitions,
- avoid installing the boiler
above appliances which might
affect boiler operation (E.G.
kitchen appliances emitting
greasy steam, washing
machines etc.),
- avoid installing natural draught
boilers in corrosive vapor or
dusty air areas like
hairdressers’, laundrettes etc.
as boiler components life span
might be considerably shorter
than average,
- leave a 350 mm space
between the upper part of the
boiler and the ceiling in order to
facilitate replacement of the
water tank magnesium anode:
this condition is respected when
between the axe of the fixing
holes of the bracket supporting
the boiler and the ceiling the
distance is 436 mm.
3.2.3 Positioning the boiler
Each boiler package includes a
metal template. It allows for CH,
DHW and gas mains
connection locating when
hydraulic system piping is being
laid out before boiler is yet to be
physically installed.
Use the lower part of the
template to mark the exact
location of gas supply, cold
water inlet pipe, DHW flow, CH
flow and return.
Since temperature of wall on
which the boiler is installed and
temperature of coaxial flue
system are lower than 60°C, it
is not necessary to keep a
minimum safe distance
between boiler and temperature
sensible surface wall.
Boilers with split duct flue
system: place insulating
material between temperature
sensible surface wall and flue
system.
