The thermocouple sends an electrical | signal to |
|
|
|

the tap, detecting the presence or absence of |
|
|
|
|
| ||
a flame at the burner. During ignition the tap | A | Safety thermocouple |
|
| |||
must be kept pressed in for 5 to 10 seconds |
|
| |||||
until the thermocouple heats up and sends | B |
| |||||
the flame confirmation signal to the tap. If the | C | Connection to the sparking unit | |||||
flame goes out, its absence is detected by the | |||||||
thermocouple and the safety tap cuts off the | D | Sparking unit |
