[Stoves] Equipment required for testing stoves

[Frank Shields]

Rolf,
I think CO2 would work fine. But looking down the road I'm thinking we may,
at some time, want to measure the CO2 coming off the flaming mass of fuel in
the process of being snuffed out especially if it takes some time to
stabilize. So just mentioned nitrogen.

Good old CO² ?
