Warning 

Before doing any maintenance: 

•  Stop the heater as indicated in the “STOP” paragraph; 

•  Switch off the power supply by means of the cut-off on 

the electrical panel; 

•  Wait until the heater cools. 

7.1. CHECKING THE HEATER AND THE GAS SUPPLY LINE 

Perform the following checks:  

• Make sure the heater is not installed where there may be a risk of 

fire or explosion  

• Make sure that flammable materials are kept a safe distance away 

• If you smell:  

• Open the windows immediately  

• Do not touch electrical switches  

• Close the gas stopcock  

• Find and repair the source of the gas leak 

• Do not use the heater if any removed panels have not been 

remounted 

• Make sure the room to be heated is sufficiently ventilated  

• Make sure that the air intake and outlet are completely 

unobstructed  

• Make sure that the heater is not covered by any sheets or covers 

• Check that the heater is in a fixed and stable position;  

• Make sure the heater is constantly monitored during operation and 

checked before being started; 

7.2 CLEANING THE EXTERIOR OF THE HEATER  

To ensure efficient operation, clean the following parts:  

• Pipes, connectors and joints: 

• Clean with a cloth.  

• External body:  

• Clean with a cloth. 

• Air inlet/outlet: 

• Remove all dirt and debris 

• Make sure the air inlet/outlet are not obstructed. 

7.3 CLEANING THE MOTOR AND THE FAN  

Clean the fan blades and the motor as follows:  

• Remove the fastening screws on the fan safety grille (C). 

• Remove the side inspection panel  

• Clean the motor with compressed air.  

• Clean the fan blades with a hard brush.  

• Reinstall the safety grille. 

• Close the side inspection panel 

7.4 CHECKING THE ELECTRICAL CONNECTIONS 

After detaching the power cable, check all electrical connections as 

follows: 

• Make sure that all connections are complete and tight.  

• If there are traces of dirt or corrosion, clean or replace the 

connections if necessary. 

• Replace any damaged wires or connectors if necessary 

7.5 CHECKING THE THERMOSTAT 

Inspect the manual reset safety thermostat as follows:  

• Clean with a dry cloth, taking care not to cut or bend the capillary 

tube. 

7.6 CLEANING THE INTERIOR OF THE HEATER  

For thorough cleaning, the heater can be cleaned and washed inside 

and outside with water. Always do as follows: 

• disconnect the electrical cable and remove it from the outlet 

• completely close all access panels  

• do not use water jets at a pressure exceeding 70 bar at a distance 

less than 30 cm 

• completely dry all parts before reconnecting the electrical cable 

7.7 CLEANING THE COMBUSTION CHAMBER 

To maintain the burner’s high efficiency and prolong its life, the 

procedure described in this paragraph must be done at least once at 

the end of the work season or more frequently if there is an 

excessive build-up of soot. Excessive soot may be caused by poor 

chimney draught, poor fuel quality, poor regulation of the burner, or 

more or less frequent alternation of burner starts and stops. Pay 

attention during operation: pulsations at start may be due to 

excessive amounts of soot. 

To access the combustion chamber: 

• Remove the side inspection panel  

•  Clean with compressed air or a metal brush 

• Reinstall the safety grille. 

Warning 

After any technical work, always check that the heater 

works correctly. 

8. TROUBLESHOOTING 

In case of serious malfunction, the electronic equipment causes the 

heater to go into safety stop, and lamp (8) lights with a steady red 

light (stop light). 

Warning 

In case of a safety stop, you have to push the reset button 

(8) for 3 seconds to restart the heater. 

Warning 

NEVER do more than two restarts in a row: unburned fuel 

can accumulate in the combustion chamber and suddenly 

flare up at the next restart. 

In case of safety stop, press the reset button (8) for at least 12 

seconds to launch a self-diagnosis programme, after which the 
button will flash at different rates (Self-diagnosis lamp) according to 
the type of safety intervention: the synoptic on the electrical panel 
shows the possible types. 

If the combustion chamber overheats, the safety thermostat (4) 

trips to shut off the burner and lamp (16) lights: to reset the burner, 

you have to shut off the heater completely, cut electrical power, 

remove the side inspection panel and push button (4). 

Warning 

You must always find the cause of the safety intervention 

and remove it before pushing reset button (8) or button (4) 

and restarting the heater. 

If the heater is still not working properly, please contact your 

nearest dealer or authorized Service Centre.
