The L-shaped probe grew legs, so this was improvised with a straight metal tube. There seems to be a persistent notion that angling the probe toward the appliance (into the exhaust stream) is the correct technique, but wouldn't this result in interference from ram air pressure of the rising flue gases?

Ted, I see your point now. Thanks for clarifying. The CAZ pressure was recorded independly of the draft. I haven't seen anyone measure both results simultaneously on one manometer, but that is a really good way to illustrate the interaction between the two forces.
... and one of the things that makes dg700 such a cool tool.
