We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Jerry
saying something like:

Ambient temp 25.1 deg C
Flue gas temp: 159.2 deg C
Oxygen: 4.6%
Carbon monoxide: 10 ppm
Carbon dioxide: 12.1%
Poison index: .0001 Rat (whatever that is)
Gross efficiency: 87.8%
Net efficiency: 93.1%
Carbon monoxide undiluted: 13 ppm (whatever that is)

The data sheet for the boiler only gives the following values:
Smoke No 0-1, CO2 12%, Approx flue gas temp: 165 deg C

Looks like you got away with not doing a smoke test. The results are
pretty good. For future reference though, you should ask to borrow the
smoke tester as well as the analyser.
