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

I borrowed a flue gas analyser to check my oil boiler efficiency
recently. It seems to be working just fine according to the analyser
but there was one parameter 'smoke number' given on the boiler data
sheet as 0-1 which the analyser didn't test for. Is there a conversion
formula that you can use to get this figure. The analyser provided
figures for flue gas temp, oxygen, carbon dioxide, carbon monoxide and
boiler efficiency.

Don't take the chance of using the analyser without doing the smoke test
first. Too high a smoke content in the flue could bugger up the sensor
in the kit.

The idea is to reduce the smoke reading first, then use the analyser.

Have a look on ebay for 'smoke tester' and 'combustion analyser' and one
or two smoke testers will pop up.

80quid a pop.
