PROBLEM
There is no spark
the pilot does not switch on when
there is a spark
the pilot does not stay on
pilot on but the main burner does not
ignite
the burner does not switch off when
the water turns off
delayed burner activation
the exchanger blade becomes dirty
in a small amount of time
there is a smell of gas
there is a smell of gas
CAUSE
- electrical cable of device is disconnected
- piezoelectric mechanism broken
- piezoelectric mechanism is not earthed
- the electrode is damaged
- pilot nozzle obstructed
- electrode activation position
- no gas supply
- air in the gas tubes
- thermocouple consumed
- broken magnet
- insufficient water pressure
- the membrane is broken
- grime on the gas shutter
- valve piston or stem is locked in open posi-
tion
- If an LPG supply, check the gas pressure
- pilot burner flame is too far from main burner
flame or is too short
- poor draught or dusty surroundings
- yellow flame
- excess gas consumption
- due to the loss of gas in the tubes, check the
tubes and find the leak
- it can be caused by obstruction in the flue gas
circuit
- excess gas consumption
- insert
- test, substitute
- test
- substitute
- clean by blowing
- regulate
- open the gas tap
- release gas
- substitute
- substitute
- repair the device pressure
- rotate the knob completely to the right
- substitute
- test, clean
- disassemble, clean and eventually substitute
- regulate and if necessary substitute the tank
pressure regulator
- regulate the flame, clean injector and pilot bur-
ner
- check the smoke channel efficiency
- Check the gas type and clean the burner
- check and regulate
- do not activate electric switches or any object
that produces sparks in local area
- check the efficiency of the smoke channel
and the flue gas conduit
- check and regulate
