Noob here... As I try to educate myself on the art of burning wood I ran across an segment in a book that discussed using flue temp to optimize your burns. I see from a search that this has been a topic here also (no surprise). I'm having a high-eff fireplace (basically a zero clearance wood stove) installed in a couple weeks and would like to know what options I have in determining the flue temp with this install. The flue will be behind a wall. The chimney pipe itself will be double walled.

Aside from guessing, how do I determine an "optimal" burn? Is there some add-on accessory I can include in the install that will let me know what the flue temp is? If so, where does it need to be installed?

The burner will be a Bis TraditionCE.
 
You cant really check the flue temps, as JB said just check the temp of the unit itself with a thermometer on the face.
 
I'm no expert, but I have put in a pyrometer on the exhaust of a car. (Yes I realize there is controvery over location and most will say it should go at the turbo inlet. :) )
They probably have something similar for a stove.
Maybe it would involve drilling a hole in the flue and installing a thermocouple and routing it to a gauge on the wall next to the stove.
Plus, you'd have to have access to it.
For a car model you'd need 12 volts.
My VDO goes to 1600F I think.
It could be nice.
Maybe someone here knows of a pyrometer with a cable for stoves.

Sorry for another dumb question...but if I read the temp off the face...what temp am I looking for that'll indicate optimal vs sub-optimal burning? Taking a temp off the face would the most convenient.

I do like the thermocouple idea into the flue although I'd need to build in access to swap out the thermocopuple when it fails. I work with similar devices and they do fail occasionally.
