I would have one on each, you are measuring two different things.

It depends on what you want to know. I have mine just above the door to watch the stove temp itself. Helps me dial in my air.

A general rule of thumb is that if you keep the stove adjusted so the thermometer above the door doesn't exceed 500 to 550 degrees F., you shouldn't be over-firing it.Thechap wrote:I don't want to over fire the stove. There isn't anything listed in the manual.

If you find that you absolutely need to, you can press it to 600 degrees on occasion. I wouldn't make a habit of it though.
And if it begins to faintly glow in the dark anywhere, you are assuredly seriously over firing it. At that point you are at about 750 degrees (or more).

IIRC my H MKII owners manual advised a maximum exhaust collar flange outlet temp of 550 deg F. I'm sure the MKIII is the same.

You'll be sweating bullets before it overheats!Thechap wrote:I don't want to over fire the stove. There isn't anything listed in the manual.
this is when you need an ir temp gun so you can shoot both spots and drive the cat nuts. seriously, if you are using one of the popular magnetic wood stove gauges it probably isnt too accurate, especially if used on the flue pipe. I have a cheap barbeque probe thermometer threaded into my flue pipe, it gives a nice accurate reading.
I have the air control knob turned out about two thirds to one turn. The temp will get up to 500 with the air control knob turned out this much. When I bank the stove I fill it to the top of the fire brick.
So, what am I doing wrong?

Here is an example of 3 styles of thermometers and values they read.

so, about 75* higher on the probe than the IR on the skin.2001Sierra wrote:Here is an example of 3 styles of thermometers and values they read.
i wonder if that's a common amount of spread between the 2 types of sampling on round pipe ?
thanks,
