do most conventional boilers have a multfunctional gas valve which includes a solenoid valve, thermoelectric valve and thermocouple? which which allows gas to to the main burner?
Also do they also have a flame superision device which prevents gas to the main burner if the flame goes out for any reason?
i am trying to learn and understand boilers a bit and just wanted to know if i was right or not
thanks for any help guys...
