BOILER OPERATING INSTRUCTIONS
Make sure that the authorised technician who tested the boiler has stamped the guarantee booklet.
The installation, first start-up, regulation and maintenance operations must be carried out exclusively by qualified
personnel (e.g. Radiant authorised Service Centres). Incorrect installation can cause damage to property and
injury to persons or animals, for which the manufacturer will not be held responsible.
During the installation, the technician must carry out the following checks:
■
The data on the data plate must correspond to that of the mains supply networks (gas, electricity, water).
■
The boiler must be regulated according to its designed use and performance.
■
The flue gas exhaust and combustion air intake system must be correctly installed and operational.
■
The exhaust gas discharge and ventilation systems must comply with the requirements of national and local
standards regardless of whether the boiler is installed indoors, outdoors or in its own cabinet (see
section
“Reference standards”.
General warnings
If there is any doubt as to whether the appliance has been tested by an authorised technician, do not attempt
to start it. All maintenance and gas conversion operations MUST BE CARRIED OUT BY PROFESSIONALLY
QUALIFIED PERSONNEL, registered in accordance with current legislation.
Make sure that the requirements relating to the air intake and ventilation of the room in which the
boiler is to be installed have been complied with.
The boilers can be installed outdoors in a partially protected location, in accordance with current
standards and where the minimum external temperature does not fall below –10°C. The manufacturer
will not be held responsible for installation in locations where the temperature falls to below –10°C.
The boiler is fitted with an antifreeze system. If the boiler is installed in a location where there is a risk of
freezing, the anti-freeze system will only come into operation if the power is on and the gas supply valve is
open (the frost protection is active even with the ON/OFF switch in OFF position). The manufacturer will not
be held responsible for damage to the boiler caused by non-compliance with this instruction.
Should any part of the boiler freeze-up, do not attempt to light it under any circumstances, but instead call the
Service Centre immediately.
The appliance’s combustion system must be checked every two years. This check includes testing the
efficiency of the boiler and must be carried out by authorised personnel possessing the qualifications as
required by current law.
Do not obstruct the ventilation openings in rooms where there are gas-burning appliances installed (boiler,
cooker, etc.).
