GENERAL WARNINGS
This instruction booklet is an integral and essential part of the product.
Should the appliance be sold or transferred to another owner, or if you move
and leave the appliance behind, always ensure that this booklet accompanies
the appliance so that the new owner and/or installation technician can consult
it.
This appliance must be used for the purpose for which it was specifically
intended.
All contractual or non-contractual responsibility of the manufacturer is
excluded in the event of damages to persons, animals or things caused by
errors in installation, adjustment, maintenance and improper use.
The manufacturer's responsibility is excluded for all damage to persons and/or
things resulting from a clear risk for the user which he could have avoided by
taking suitable safety measures.
After having removed the packaging, check the contents for breakages. If you
are in doubt do not use the appliance, contact your supplier.
Do not leave the packaging materials (wooden cage, nails, staples, plastic
bags, polystyrene foam, etc.) within the reach of children, as they are potential
sources of risk.
The installation must be performed in compliance with the regulations in force,
following the manufacturer's instructions, by professionally qualified personnel.
The term “professionally qualified personnel” means persons with specific
technical skills in the sector of steam systems.
To guarantee the efficiency of the appliance and ensure correct operation, it is
indispensable to have regular maintenance performed by professionally
qualified personnel, following the manufacturer's instructions.
Any repairs to the appliance must be carried out using only original spare
parts.
If you decide not to use the appliance for a long period, ensure you have
professionally qualified personnel to carry out the necessary operations to
preserve the generator.

GENERAL SAFETY RULES
The use of any component utilising energy power, fuels and water requires
that certain fundamental rules be respected, such as:
Do not allow children or unskilled people to use the appliance;
If you notice smell of gas, do not turn on electric switches, household
appliances, telephone or any other objects that could cause sparks. If this is
the case:
- open doors and windows immediately to clear the air in the room;
- turn off the fuel taps;
- contact professional qualified personnel.
Do not touch the appliance with wet or damp parts of the body and/or with
bare feet.
Do not perform any maintenance and cleaning operations without having
disconnected the electric power and turned off the fuel supply tap(s).
Do not pull, disconnect, unwind electric cables coming from the boiler, even if
they are disconnected from the mains supply.
Do not block or reduce the ventilation openings in the room to prevent the
formation or toxic and explosive mixtures caused by gas leakage; it is also
uneconomic and polluting because it causes bad combustion.
Do not expose the appliance to atmospheric agents.
The generator has not been designed to work outdoors and is not provided
with automatic anti-freezing systems. Keep the boiler turned on in freezing
conditions.
Other important warnings to be respected:
-If the power cable of the appliance is damaged, have it replaced by
professionally qualified personnel;
-do not fix (and do not allow other persons to fix) electric cables on the
system pipes or near sources of heat;
-ensure that the earthing cables of the appliance are not connected to the
water system;
-do not touch the hot parts of the system (in particular the door and the
smoke box) as they normally remain hot even for some time after the
appliance has been turned off.
In the event of a water leak, turn off the system and contact exclusively
professionally qualified personnel.
