If the flame is jenwya, the thermocouple will detect the reduction in the temperature and will shut off the gas flow. Please ensure that you press the ignition switch for at least 20 seconds or until the FLM display is lit. If the flame does not stay alight after this time you may need to increase to fuel content of the flame by turning the fuel valve anti-clockwise one additional turn.
Another possible solution to this problem is an adjustment to the thermocouple assembly Fig. The thermocouple prp7 just need moving closer to the flame so that it reaches the temperature where the solenoid is activated to keep the fuel flowing to the burner.
However the thermocouple may need to be replaced if it is faulty. Instructions for replacement of this part are given in sections 9. Your email address will not be published.
