▲ Simple structure, low price
▲ Good flame selectivity
▲ Fail-safe design
▲ Poor sensitivity
▲ Suitable for low-power burners only
▲Ion rods should be able to be in the flame
▲The flame must be in contact with the igniter nozzle to achieve flame ionization
▲The calorific value of the gas should be high
▲Clean combustion air
▲Suitable air-fuel ratio
