Can anyone tell me where the best place to put a magnetic stove thermometer on a Harmon MarkII?

I think the hottest place is just above the door on the front of the stove body.. maybe on either side near the top. If you can borrow a laser thermometer or buy one from http://www.harborfreight.com you can search around for the hottest spot.

The hottest spot will give you the fastest response and closest to true inside the box temps .

Thanks Greg,I have it on the side near the top but I'll check above the door next time fire it up.

I've never been real concerned with stove temp, I keep my magnetic thermometer on the stack about a foot above the stove.

Maybe I'll pick up another thermometer or 2 for the stove itself and see if I can fine tune things a little better.

Steve the best way to see what the true temp is Get youself a Prob thermomenter and stick it in your stack pipe before
your baro that will tell you your true temps coming out of the stove and how much heat is going up and out of the
chimney then you can control the air flow coming in the stove The mag thermomenter are and will be off by 30 to 40% some by 50% The Prob thermomenter will be more accurate and more true to the temp coming out of the stove get one

with a 4" prob and that goes up or over 1500F or 1700F you will see temps on a good hot burn getting close to these
temps on a hand fed stove coming out of the stack pipe off the stove check them out on the link below I know they are pricey but well worth it for the accuracy you will get in the long run it will pay for it self by helping you set the stove up better and it will save on the coal use by helping you slow down the burn rate by adjusting the air coming into the stove
I also like using a magic heatreclaimer on the stove it will cut the heat loss in half going up the chimney Take care Steve let me know when you want to go look at some stoker boilers

Hi,
Good question and answers. I was going to post a similar question but I hope it's ok to ask it here.

First my answer.. I have a mag thermometer mounted on top of a tee which comes right out of the stove. The baro damper is in this tee. I also recently bought one of these IR thermometers. http://www.northerntool.com/shop/tools/ ... _200316947

Last night the mag therm on the tee was just over 200 and the IR confirmed this so the mag seems more accurate than I thought it would be. I'm not sure if having the baro right there affects the actual gases temp reading but I guess it could. The stove sides read about 300 with the IR.

So, my question. The stove was cleaned out before I lit it. When I open the ash door I can see a red reflection of the fire in the clean ashpan. The tiles under the stove were about 190-200 degrees. This is hotter than I would like to see. Also, the draft control was about 200 degrees. Normally, this is cool to the touch. My theory is that there was no ash on the grates or in the ash pan area and the heat was baking through. There's been discussion about the ashpan being smaller than the grates on the Harman and now I think it's a good idea to have a little extra ash remaining in the stove as insulation. What do you think? Has anyone else noticed this?
