 is a gas boiler which must be

installed in accordance with the latest re-

gulations or rules in force. For the boiler
category, which changes according to the
destination country, see page 4.

NOTE:

Observe the corresponding technical rules

and the building supervisory and statutory
regulations of the country of final use when
installing and operating the system.

Always ensure that an appropriately

specialised company is entrusted with
installation, gas supply and flue gas
connection, commissioning and power

supply connection, as well as all servicing
and repair work.
Work on gas conduits and fittings must

only be carried out by a registered service
provider.
The system must be cleaned and serviced

once a year. This includes an inspection

Keep the packaging material
(cardboard box, plastic strips,
plastic bag, etc.) out of the rea-
ch of children as it represents
a choking and suffocation ha-
zard.

In addition to the boiler packaging contains:
-

a bag with:

-

installation, use and maintenance
handbook,

-

warranty card

-

template for fixing the boiler to the wall,

-

2 dowels with screws hook to fix the boiler
to the wall,

-

Only for models 

TFS,

 a diaphragm for flue

gas outlet

UNICAL refuses all liability for
injury to persons and animals
or damage to property resul-
ting from non-observance of
the above.

of the entire system to see if it is in full
working order.
Defects and faults must be eliminated

immediately.
Please note that we can accept no liability
