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 exceed 
levels of danger for health.
•

A good ventilation is guaranteed when the room’s volume in m

3

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

2

 is at least 0,003 times the nominal calorifi c 

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

3

 is at least 10 times the nominal calorifi c power (in kW) of 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.
