Here we are http://www.rainbow-conversions.co.uk/gas-accessories/trio-gas-alarm.html Looks an easy install. And it can operate a relay so it could be used to automatically switch off the gas via a solenoid...
We have a FireAngel CO alarm, and before I fixed the tinware it had a tendency to go off after starting the engine if you didn't drive away quickly. Eeek! A CO alarm is useful for the hot air system (engine exhaust) as well as for cooking. They're required in light aeroplanes with similar engines and exhaust-jacket cabin heating.
