Carbon Monoxide Detector

The alarm sounds at a variable level dependant on average 
levels over a period but not below 30 ppm.

Something I have been meaning to fit for a while but the need was highlighted during my very cold trip in April and May when I was using the cooker a lot for cooking and the grill occasionally to keep warm.

I finally did it and trials show that with the Dorade and washboards vents open the oven and oil lamp registered 0, a test with a small gas fire got it up to 15 ppm after 45 minutes.

Not shown is a smoke detector - just in case.
