I don't know about all hearing systems, but if our heater (we have circulating hot water heat) has no flame, the gas valve shuts.
It's on a timer. The valve opens, the igniter sparks, and within a few seconds the current should pass through the ions in the flame to close the circuit.
If that current isn't sensed, it shuts the valve, so there is no gas flowing.
Hence, our system wouldn't blow up, but it would be useless.
Our system is designed and built by Crown Boiler. I don't know if other brands work that way.
But, you are doing a good service to fellow DUers.
