Mechanical problems Blocked or damagedfan
>Check the fan>Unlock the fan>Replace the fan
YES
Switch ON
Connect to electricsupply
Connect to gas bottle
No power >Use a tester to check thepower supply system
Faulty or damagedpower cord >Replace
Incorrect or incompletewiring connections
>Check>Correct
NO
23
Does the flameshut off?
YES
NO
Immediately afterignition
During operation
Faulty gas valve >Check>Replace
Low gas inflow
>Room temperature too lowand/or insufficient gasevaporation: use a bigger gasbottle or more gas bottles
Does theflame light up?
NO
YES
Faulty ignition
Damaged electrode >Replace
Wrong distancebetween electrode andburner
>Regulate the distancebetween electrode and burner
Faulty piezoelectricignitor
>Check>Replace
Faulty safety thermostat(open contact)
>Check>Replace
Absence connectionpiezoelectric-electrode
>Check cable>Replace cable
Piezoelectric notconnected to ground
>Check>Connect correctly
Weak flame signal
>No correct combustion>Faulty or wrong pressureregulator>Low room temperature and/orinsufficient gas evaporation:use a bigger gas bottle or moregas bottle>Faulty thermocouple: checkand replace
Safety thermostatactivated
>Unit is overheated:check and find a cause(hight room temperature,excessive gas inflow,insufficient ventilation, ecc.)>Unit is not overheated:thermostat faulty

NO
YES
Combustionis OK ?
Low air/gas ratio
Insufficient air flow>Obstructed air inlet>Low voltage and/or low motorrpm: check voltage, motor,coupling and fan
Excessive gas flow>Wrong gas type>Faulty or wrong pressureregulator>Wrong nozzle size
High air/gas ratio Insufficient gas flow
>Low gas pressure>Low room temperature>Too small gas bottle>Obstruction of parts of the gascircuit (nozzle, gas valve, ecc.)
