We have a 7 BBL ABE Direct Fire Combi-System and we are about to install our flue for the burner. Before we install it, someone suggested that we install a port for temperature and emission checks.

That leads me to my questions:
How often do you check the efficiency of your combustion? Just dialed in at the first brew? Annually?

Do you do it yourself with a Combustion Analyzer? Or do you have a specialist come out and each time?

If you do it yourself, what analyzer did you purchase?

We are currently looking at this one: http://www.trutechtools.com/testo-31...-and-check-kit
