Check that the gas bottle(s) is (are) filled. Press the button of the
safety cut off valve
Check solenoid valves
Check the electrical connection
Check the overheat thermostat
Adhiust according to the instructions
Replace ionisation electrode
Clean the protection gauze
Check if the grilles at the inlet and outlet are dirty
Check that there is sufficient fresh air supply
Check that the heated air can flow out freely
Check the thermostat and replace, if necessary
Depress the valve button for about 10 seconds
Check line continuity between igniter and electrode
Check the setting of the electrode (see scheme)
Check the position of the thermocouple (see scheme)
Check the thermocouple and replace if necessary
Clean terminals of circuit breaker or replace
Replace pressure regulator
Locate the leak with soap-suds and replace the defective part
Close the gas supply, allow the available gas in the hose to burn, remove
plug from the socket, remove solenoid valves, clean and remount
