like to ask were does the thermometer go, on the stove or pipe, and what range for each?

I have one each place, and here's why. I can always tell when the stove is burning as it should and at its peak efficency. Meaning, if the flue temp is higher than the stove temp I throttle the stove's air back some to not send so much heat up the stack allowing the stove to heat up as it should. Remember, a hunk of metal like our stoves can only heat up so fast. The BTU's it can't absorb goes sailing right up the flue and are wasted. I have found that the typical differencial between stove and flue pipe is about 200 - 250 deg F, with the stove being hotter. That way I know the stove is crusing good and burning hot.
As for temps, it all depends on the stove. Typical flue temps should be 350-400 deg F or so, with the stove at 500-600 deg F. The hotter the better (to a point) as the hotter you burn the less cresote you create, which is a good thing!
Craig thanks , tons of info on this site.
What stove is this? Is it connected with single or double-wall pipe?
From your previous posts, I'll assume this is for a US 2000 stove, is that right?
I like to have both also. It's good to have temperature information from both the stove and the flue to maintain optimum operating conditions and safe conditions.
For stove top use, I would suggest this thermometer. http://www.condar.com/stove_top_meters.html Your manual may suggest the best place, but in general you put it on the top about in the center in front of the pipe. But stove top temps can vary quite a bit on a top, so you may want to find the hottest spot and leave it there. An infrared thermometer is useful for that.
For the flue, it depends of if you have double wall pipe or single wall. I suggest this one for single wall stove pipe (the Chimgard) http://www.condar.com/stovepipe_meters.html Be aware that this type reads the surface temperature of the pipe. The internal temps will be roughly double..
For double wall stove pipe, this one: (the Fluegard) http://www.condar.com/probe_meters.html
These Condar thermometers are the most popular on this forum. They measure not only the temperatures but have safe and unsafe zone indications. The temps you want to operate at depend on various factors such as the type of stove, etc.
us stove 2000 and single wall, thanks for all the replys.
condar, for both flue and stove top. IR for exact measuring.
Interesting question. I recently purchased the Condor unit designed for double wall pipe. Before installing it I sent a message to Duravent asking if the Condor Double wall model could be used with a double wall Duravent Telescoping Pipe. I am waiting for a answer and and will post Duravent's recommendation when they reply. No doubt many have installed the Condor Double Wall model in their stove pipe, but has anyone installed it in a telescoping section of Duravent DoubleWall?
Greetings eggie, Happy Thanksgiving, We have here at the lower spread a double walled stove and single wall pipe to the ceiling. We have the thermometer 18" above, the highest point ,where the pipe exits the back of the stove. At the mountain ranch we have a single walled stove and single wall pipe. We have a heat exchanger on the pipe above the stove, the pipe exits the top of the stove, so we have the meter just above that.
Didn't have one for years, now I don't know how I did without them.
