•   Unscrew and remove the ionisation electrode (6); 
•   Undo the screws that secure the combustion head (3) 

to the combustion chamber (1); 

•  Remove the three screws on the burner head plate 

and change the diffusion ring securing it in such a way 
that the ignition electrode is equidistant between the 
two subsequent holes; 

•   Calibrate the gas pressure switch (4) on the gas valve group 

(Fig.3): 

•   Regulate the gas pressure switch to a value equal to 

80% the supply pressure; 

•  Regulate the pressure regulator for the gas valve group 

(Fig.3); to the burner pressure stated in Tab. I.: 

•  Connect a gauge to the pressure intake (1) upstream 

and a second gauge to the pressure intake 
downstream (2) of the valve group; 

•   Start the heater and take the reading off the 1st supply 

pressure gauge and if necessary adjust the pressure 
regulator (3) for the gas supply system until the correct 
supply pressure shown in Tab. I is reached; 

•  Take a reading off the 2nd working pressure gauge 

and if necessary use a screwdriver to adjust the 
pressure of the gas valve group (4) to restore the 
working pressure shown in Tab. I 

•   Apply the adhesive label with the words “SET UP FOR …” 

corresponding to the type of fuel and the category chosen 
on the gas valve group. 

OPERATING INSTRUCTIONS 

START-UP 

The heater works in “heating” mode, turning the switch (9) to  

 . 

To start the space heater (Fig. 1): 
•   Make sure the switch (9) is set to “0”; 
•  Switch on power to the heater by means of the isolation 

switch on the power switchboard; 

•   Move the switch (9) to position  ; 
•   Operation will only be automatic if a thermostat or another 

control device is connected to the thermostat plug (10). 

•   If after these operations, the generator does not work, refer 

to the “FAULTS, CAUSES AND REMEDIES” section and 
find the cause. 

STOP 

To stop operation turn the switch (9) to “0” if operation is 

manual, or to room thermostat if operation is automatic. 

Lastly, close the gas supply stopcock and turn off the isolation 

switch. 

The flame goes out and the fan motor will continue to run until 

the combustion chamber has cooled down completely. 

The flame goes out and the fan motor continues to work 

according to the preset mode (timed post-ventilation or 
continuous post-ventilation). 

VENTILATION 

The heater can work in “ventilation” mode turning the switch 

(14) to   : the fan motor starts, while the burner is off. 

TRANSPORT AND HANDLING 

The space heater can be lifted up and suspended using the 

four anchor hooks provided in the casing. 

 
Warning 

Before moving the unit: 
•  Stop the machine as indicated in the “STOP” 

paragraph; 

•  Disengage the power supply by removing the 

plug from the power socket; 

•  Fully unscrew the fitting that connects the gas 

pipe to the heater; 

•   Wait until the heater has cooled down. 
 

Warning 

During transportation and/or storage, make sure 
the gas valve group and gas connection pipes are 
not knocked or damaged in any way. 

MAINTENANCE 

For proper working efficiency the fans, the combustion 

chamber and the burner must be cleaned periodically. 

Warning 

Before performing any maintenance operations: 
•  Stop the machine as indicated in the “STOP” 

paragraph; 

•  Disengage the power supply by removing the 

plug from the power socket; 

•   Close the gas supply stopcock; 
•   Wait until the heater has cooled down. 

The heater can be cleaned and washed with water. It is 

however necessary to ensure that: 

• the power lead is disconnected and unplugged from the 
power supply socket 
• all access panels have been completely closed 
• no water jets are used at a distance of less than 2 m 
• all parts of it are completely dry before plugging in the power 
lead again. 

Warning 

Cleaning the heater by the wrong procedures can 
cause 
damage to things and/or persons. 

Cleaning must be carried out by removing any foreign bodies 

from the fan suction grills.
