Looks to me like that is a picture of CAZ testing...it's a combustable appliance. I do like the idea of CAST though. I'll ponder that one as I eat a grinder...

Exactly.  My point is that we find teaching the entire combustion testing protocol to be more effective and easier for people to learn when we are specific about the test - what we are actually testing.

For thoses that need more infomation then a quick title...

 

The women in this picture is actually testing for ambient CO (Bugaboo for accuracy!) as well as spillage on a atmospheric Domestic hot water heater that is in a combustion appliance zone. Following BPI's combustion safety test procedure for vented appliances. (procedures number 3 and 5). Just a sample photo of some of the tests that are conducted in a CAZ! Here in the North east when someone states they are conducting CAZ testing, it just means that they will be performing all the tests required for that specific  appliance type. Without adding more acronyms to and industry that has too many already, we could start a new one combustion appliance safety testing (CAST).

This is a photo not a Q/A report,  lunch meat on bread is called sandwich, hero, grinder, hoagie, sub.

A picture says a thousand words - testing in a CAZ

Would love to influence the industry to stop using "CAZ Testing" when what they really mean, in the case of this photo, spillage testing.  CAZ means "combustion appliance zone" and really, all we really test regarding the CAZ itself is its relationship to the rest of the house and the outdoors, under normal (natural) and when we attempt to depressurize it the most (net worst case CAZ depressurization).  We call our testing by the name of the test:  ambient CO testing; undiluted flue gas testing for CO; draft pressure testing; spillage testing; combustible gas leak testing...  not "CAZ testing" unless we are talking specifically about the CAZ.  Just a thought!  Bugaboo for accuracy!

The pitch here is about 1/2" per foot

the vent pipe appears to have inverse fall based on this picture....:)
