The one on the stack says Im in the zone. The one on the deck says im overfiring

Who is right ?
 
My rutland, identicle to your's, is 80 degrees off. Get a pot of water, just before it is a "rolling" boil, dip the thermometer in the water until it is rolling. Don't set it in the water, dip it. If you set in the water it will contact metal and read the temp of the pot and burner. Mine was 80 degrees off....

You may be still overfiring, that I can't tell you but you can synchronize the meters.
 
I am unsure which is right but..... To look at that stove pipe I have to wonder why is it sooooo white????? Perhaps a chimney fire ???

Is that a galvanized pipe? If you reverse them, do you get the same readings?
 
And it this is insulated pipe it will for sure be cooler!

Are the thremoms adjustable ?
 
Galvanized pipe as stove pipe can equall out gassing from pipe and very, very bad things. Well at least if you want to breath.

The stove top and flue temp can be worlds apart in the operation of the stove so one could be in an over fire condition and the other one not.
 
my guess is the thermometer you have on the deck is made for your flu reading so if that would be the temp you would be getting on your flu you would be over heating. What temp do they consider over firing?
 
I'd put them side by side on the stove top and see if they agree with each other. These are not exactly precision instruments.
 
Holy crap that stovepipe scares me! There is no way I would have that thing in my house. Single wall pipe is relatively cheap you should replace it.
What are the little bricks on top of your stove for?

both say > 550 is overfire

ah good idea- they seem close now
i guess there really is a temp diff so

my deck in overfire while my stack is fine ?

how do I fix that ?

I would make sure to calibrate them as I said in an earlier post! If they are 100 degrees off you may be ok!

there you go, 550 reading on the stack would be too high and your stove, temperature would be 700-750 give or take. but 550 for your stove box is A OK!!!!



ANYONE else agree?

Yep 550 overfire would be a temp sensor made for a flue.
 
550 overfire is for the flue, not the stove top. Those temperature ranges are for when it is used as a flue thermometer.

Before, (did you remove the picture?) I thought you had the thermometer on the stove's top step and that put the reading in the higher range. They read fairly close together at 550F, lets see how they read side by side on the hotter location.

OK so I can expect that the deck is hotter than the stack? yes ?

If so then im OK

stove box will be a lot hotter, right now my stove is just about out and I have a flue temp of 220 and my temp guage on the side of the firebox is 420.
 
Correct, the stove top is usually hotter, except when the stove is first warming up. I would expect to see around 500-700F on the stove top and 200-450 on the flue surface with that stove.
