Congratulations on your choice of a high quality product. We strongly advise you to read the following instructions in order to
guarantee the optimal operation of your appliance. We are sure that it will be entirely to your satisfaction and will meet with all of
your expectations.
Important recommendations
For a proper operating of the boiler, follow carefully the
instructions.
Any intervention on the appliance and heating equipment
must be carried out by a qualified technician.
The manufacturer is not liable for any improper use of the
appliance or failure to maintain or install the unit correctly
(the user shall take care to ensure that the system is
installed by a qualified fitter).
Check the seal on the gas and water pipe connections.
Checkthat theequipment isproperlysetfor thetype ofgas
used.
Keep to the polarity shown on the terminals : phase (L),
neutral (N) and earth 4.
Check regularly that the installation contains water and is
pressurised.
Danger of burning in direct contact with the flame
detection cell.
1 Aeration
Do not obstruct the air inlets in the room (even partially).
France: the cross section of the aeration vent, which is compulsory
in the premises in which the boiler is installed, must comply with the
DTU 61.1 (P 45 204) standard and, in particular, with the instruction
on general improvement work (Book1764 April 1982).
Germany : the cross section of the ventiliation vents, which are
compulsory in the room in which the boiler is installed, must comply
with the VDI 2050 form 1 standard and with other prevailing
regulations
Other countries: the cross section of the aeration inlet, which is
compulsory in the premises in which the boiler is installed, must
comply with the standards in force in the country.
2 Maintenance
- The servicing and cleaning of the boiler and the sweeping of the
flue gas pipe and the bleed pot must be done at least once a year
by a qualified professional. We recommend taking out a
maintenance contract.
- Regularly check the level of water in the system and top up if
required,takingcare that cold water is notaddedsuddenlyintothe
boiler when it is hot. If this operation is repeated several times per
season, locate the leak and repair it.
Do not drain the installation, except in cases of absolute
necessity. For example: Several months' absence with the
risk of ice in the building.
3 Adapting to another gas
The operations required to switch from one gas to another must be
carried out by your fitter.
