Two lockout conditions may occur that can be reset by the user:
a - Burner lockout signalled by the corresponding light 6 (Fig. 1). Refer to the burner manual.
b - Activation of the safety thermostat when the temperature in the boiler reaches the limit value above which a dangerous situation may arise.
To reset operation, unscrew cap 3 and press the reset button.
If the problem occurs again, contact qualifi ed personnel or the service centre.
In the event of faults and/or poor operation of the appliance, it should be deactivated. Do not attempt to repair the appliance. Contact profes-

2. INSTALLATION
General instructions
This appliance must only be used for the purposes it has been specifi cally designed for. This appliance is used to heat water to below-boiling
temperatures at atmospheric pressure, and must be connected to a heating and/or domestic hot water distribution system, according to its
characteristics, performance and heating capacity. All other uses are considered improper.
THE BOILER MUST ONLY BE INSTALLED BY QUALIFIED AND SPECIALIST PERSONNEL, IN COMPLETE COMPLIANCE WITH ALL
THE INSTRUCTIONS REPORTED IN THIS TECHNICAL MANUAL, THE LEGAL STANDARDS IN FORCE, THE PRESCRIPTIONS OF ANY
NATIONAL AND LOCAL STANDARDS, AND ACCORDING TO THE RULES OF GOOD PRACTICE.
Incorrect installation may cause damage to people, animals and things. The manufacturer will not be held liable in such events.
Place of installation
The room in which the boiler is installed must have ventilation openings to the outside according to the standards in force. If the same room
features a series of burners or exhaust devices that can operate at the same time, the ventilation openings must be large enough for the
simultaneous operation of all the appliances.
The place of installation must be free of fl ammable objects or materials, corrosive gas, dust or volatile substances that, sucked in by the
burner's fan, may block the internal tubing of the burner or the combustion head. The environment must be dry and not exposed to rain, snow
or frost.
Positioning the boiler
The minimum spaces shown in the fi gure must be complied with. Specifi cally, make sure that after as-
sembling the boiler with the burner on the front door, the latter can be opened without the burner hitting
against the wall or any other boiler. Leave a free space of at least 100mm on the side that the door swings
towards.
