High Temperature Alarm?

Here is a picture of one that I replaced because I forgot to take it out when I cleaned the Chimney and bent the chit out of it

 

I contacted Auber and they say they think it's from an old batch, it seem they had 4mm before?

mine look like your, without the bend

 

I did straighten it out and saved it

 

Thank you for posting Well Seasoned ! You did exactly that in educating an inexperienced newcomer in myself. I won't forget this post and it will be part of our family discussion going forward.

 

Recently discovering the Auber product, we installed it to replace the spring actuated SB brand probe that sticks into the flu. Auber is set to 600ºF hot and 250ºF cold. Quite a difference in fire management. When we had the SB probe, we'd start a fire, open the damper and the draft, and leave it until it was going ok (maybe 10-20 minutes) then start piling on wood. With the Auber, within a few minutes the high alarm rings so we close the damper. The temp drops immediately and the cold alarm rings. Open the damper again and the hot alarm rings within 30 seconds. The damper on this Harmon Oakwood stove is either open or closed, no in between, unless a person decides to sit there and hold onto the damper lever and try to balance the damper plate to leave it just open a little bit. PITA really. So it takes about 10-15 minutes of management to get the Auber reading somewhere around 350ºF. Then we can close the damper and start manipulating the draft. I can't imagine how hot the flue must of gotten previously when just using the SB probe.

 

600 F temps. in the inside of the flue are pretty low. I run my flue gasses pretty cool but my alarm is set to 750F and my usual level to start cutting back on draft is when the temp. touches 700F. My particular stove has a long flue gas path with the damper (actually a moving sled inside the stove) open or closed so the flue temps. do not rise very quickly; other stoves with a bypass that basically opens under the flue will show a much faster rise in flue gas temp. after starting a fire.

Most wood stoves run pretty hot regarding flue gas temps, often well over 1,000 F under regular circumstances. I try to keep mine down for a couple of reasons- it is usually accepted that temps. of 800F + must be reached to start a chimney fire so that is kind of my 'hard ceiling', plus the hotter the flue gasses, the less efficient the burn (assuming the stove is burning without much if any smoke of course).

Digital temp. probes allow an entirely new view of such a simple thing as 'burning wood' because even small adjustments have an immediate effect, we just never knew it until the stove was monitored with less than one degree, fast- response measuring devices.

It is nice to not have the leg time Like other types of thermometers ,So you can really see what's going on , When my stove is cruising The flue runs 650 to 700
My High temp alarm On my Auber flue probe Is set at 900 , That is for emergency I know something is going wrong ,I hit that A couple of times on accident But ,alarm went off I dealt with it and there was no problem , once in awhile it will hit 800 While getting the stove going .
My bottom end cold temperature alarm is set at zero because I don't see the need for an Cool camp alarm
