The room of the burner shall have openings to the outside in compliance with the regulations in force. In case of doubt
as to the air circulation, measure the value of the CO when the burner is working at its maximum capacity and the
2
room is ventilated only through the openings destined to feed the air to the burner; then, measure the value of CO a
2
second time, with the door open. The value of CO thus measured must not change in a significant way. In case more
2
than one burner and one fan should be placed in the same room, this test shall be effected with all the units working
at the same time.
Do not obstruct the ventilation openings in the room where the burner is installed to prevent:
- the generation of toxic or explosive mixtures
- the combustion with inadequate air, which would cause a dangerous, expensive and polluting working.
Do not leave the unit exposed to rain, snow and freeze.
The room of the burner shall be kept clean and free from volatile substances, which could be taken inside the fan and
obstruct the inside lines of the burner or of the combustion head. The powder is extremely harmful, especially if it settles
on the fan blades, where it will reduce the ventilation and cause pollution during the combustion. The powder could
also settle on the back side of the flame stabiliser disk in the combustion head and cause a poor air-fuel mixture.
The burner shall be fed by the fuel mentioned on the data plate with the features and data shown in this Manual.
The supply line shall be perfectly sealed. It shall also be provided with all the control and safety devices required from
the regulations in force. Make sure that no external materials enter the line during the installation.
Make sure that the electric system is adequate for the features shown on the data plate and in this Manual. The burner
shall be properly connected to a safe earthing system, in compliance with the regulations in force. In case of doubt,
ask qualified personnel to accurately inspect the installation.
Never exchange the cables of the neutral with the cables of the phase.
The burner may be connected to the electric network by a plug-socket connection, only if this is provided in such a way
that the configuration of the coupling prevents the reversal of the phase and of the neutral. Install a service switch in
the control panel for the heating unit, as required from the current regulations.
The whole electric system and all the sections of the cable shall be adequate for the maximum value of input power
shown on the data plate of the unit and in this Manual.
In case the feeding cable of the burner results faulty, refer to qualified personnel only.
Never touch the unit with wet parts of the body and/or barefooted.
Never pull electric cables and keep them distant from heat sources.
Remove the packing material and make sure that the contents has suffered no damage. In case of doubt do not use
the burner and contact the supplier. The packing material (wooden crates, paperboard, plastic bags, foamed polystyrene,
etc.) represents a form of pollution and may become a source of hazard. It shall be gathered and disposed in a proper
way.
