USE IN ENVIRONMENTS WITH
PERMANENT PRESENCE OF
PEOPLE OR ANIMALS
• The generators can be used in well-ventilated rooms and when
the percentage of polluting substances in the air does not ex-
ceed levels of danger for health.
• A good ventilation is guaranteed when the room's volume in m
is at least 30 times the nominal calorifi c power (in kW) of all the
machines used in that room and when an air circulation through
doors, windows or permanent openings can be guaranteed,
whose size in m is at least 0,003 times the nominal calorifi c
2
power (in kW) of all the machines used in that room.
• The apparatus should not be used for continuous heating of
stables and farms.
USE IN ENVIRONMENTS WITH
NO PERMANENT PRESENCE
OF PEOPLE OR ANIMALS
• Signs must be displayed prohibiting people from stopping per-
manently in that room.
• The generators must only be used to dry rooms, provided that
there is a guaranteed quantity of air exchange necessary for
combustion.
• The necessary quantity of air is when the volume of the room
in m is at least 10 times the nominal calorifi c power (in kW) of
3
all the machines used in that room.
• A normal air circulation through doors and windows must be
assured.
CLEANING AND
MAINTENANCE
Periodically and before putting the appliance away after use,
clean it.
• Before starting any kind of maintenance and repairing opera-
tions, it is absolutely necessary to unplug the apparatus.
• To provide maintenance inside the compartment commands.
• Close the cylinder tap.
• Maintenance concerns solely cleaning the burner outlets, the
eventual replacement of the calibrated nozzle and the replace-
ment of the fl exible hose.
• Clean the burner periodically if it is used in a dusty place.
• When the appliance is run by radio-control, check wear of the
gas pipe and power cable; if you have any doubts about their
condition, call in the servicing department.
• After each servicing operation a soundness test shall be car-
ried out over the gas circuit by aid of soap water.
