Types of boiler - ue exhaust connection
- coaxial connection of the boiler to the suction/exhaust ducting
- split connection of the boiler to the exhaust ducting with air
suction from outside
For details relating to connection lengths and direction changes,
please consult the “exhaust types” table.
The suction/exhaust ducting connection kits are supplied
separately from the appliance, according to di erent installation
solutions.
If there is any loss of pressure in the piping, please refer to the gas
ue accessories catalogue. Supplementary resistance must be
borne in mind during the sizing process mentioned above.
For the calculation method, equivalent length values and
installation examplesplease refer to the gas ue accessories
catalogue.
WARNING
Make sure that the ue gas exhaust and ventilation
ducting are not obstructed.
Make sure that there are no leaks along the ue gas ex-
haust ducting.
Connecting the Flue
The boiler is designed to operate in B mode (by drawing air from
the room) and in C mode (by drawing air from outside).
When installing an exhaust system be careful when handling the
seals, in order to avoid ue gas leaking into the air circuit.
The horizontal kit must be tilted with a downward slope of 3%
towards the boiler to evacuate the condensates.
When type B installation is used, the room in which the coiler is
installed must be ventilated using a suitable air inlet which complies
with current legislation. In rooms where corrosive vapours may be
present (for example, laundry rooms, hair studios, rooms where
galvanic processes take place, etc.) it is important that type C
installation is used, with air for combustion drawn from outside. In
this way the boiler is protected from the e ects of corrosion.
When implementing coaxial suction/exhaust systems the use of
authentic accessories is obligatory.
The ue gas exhaust ducting must not be in contact with or placed
near ammable materials, and must not cross building structures
or walls made using ammable material.
When replacing an old boiler, the ventilation and ue gas exhaust
system must always be replaced.
The ue gas exhaust ducting joint should be created using a male/
female coupling and a seal.
Couplings should always be arranged so that they go against the
direction of the condensate ow.
GENUS PREMIUM HP 45/65
is equipped for connection
to a 80/125 coaxial ue gas
suction and exhaust system.
Mount the ue gas exhaust
and air suction collector
using the screws provided.
Make sure that the seals are
positioned correctly.
A suitable adapter must
be used when using split
suction and exhaust systems.
GENUS PREMIUM HP
85/100/115/150
is equipped for connection
to a 100/110 twin-pipe ue
gas suction and exhaust
system, but is necessary to
use the adapter.
A suitable adapter must be
used when using coaxial
system.
