central wi.
stove installer said to put it next to stove pipe on iron where pipe starts but half the spring wont touch the metal with double wall pipe that cant be very accurate then the next question will be if you place it on middle stone what would max safe temp be on thermometer
 
I'm pretty sure Hearthstone recommends placing a thermostat on the middle top stone and not to exceed 600 degrees.
 
This comes from page 22 of the Mansfield manual

Monitoring Stove Temperatures
Monitor the stove temperatures with a stove thermometer (available from your dealer) placed on the top center stone of the stove. The thermometer could read as high as 600ï‚° F (427ï‚° C) on high burn and 300-400ï‚° F (149-240ï‚° C) on low burn

Here is a link to the manual (broken link removed to http://www.hearthstonestoves.com/assets/files/document_library/Mansfield8011Manual.pdf)

thanks again, its amazing what a stove dealer will tell ya verses reality,he said never ever run over 350 center stone,said he had a mansfield in his home as well,i could tell you some stories about our stove buying experience
 
Read the manual online before you buy the stove...then you can figure out how much the dealer knows about the stove he's trying to sell you.

ok thanks but if a cast stove has similar max temps is that an accurate safe level going through soap


Cast iron can safely go higher than 600°.

And yes, 600° is the recommended max temp on a Hearthstone.
 
already bought it just needed clarifying on dealers recommended temp verses owners manual, we knew what stove we wanted what to pay and how big to heat 2250 sq. just didnt know where to buy it then found out through local folks that this is the place to go and it was a small nightmare but its in looks grate and now we wait for winter ill get some pics up soon so i can show her off, not wife, stove ;-)

That's funny, 350 is just getting warmed up, I don't see how he could keep it that low unless he's burning wet wood or small loads.
 
im thinkin hes not an experienced stove guy and took me for the same, doesnt matter got what i wanted and think we have a pretty good idea how to run it and this web sight is always around to help im sure

Unbelievable.

I wonder how many others believe the same thing.

Well, we were getting a lot of "soapstone stoves can't get over 400°" threads for a while. So, I'm just going to blame this one dealer for all the miss-information we deal with.
 
Even though the stone can get up to 600 it is tough for me to get it that high on purpose. I have a chimney system that is per the manual's minimum specs and even with good wood and ideal loads it takes a long time and lots of effort to hit 550.

I worry more about overtemping the flue. That bugger has a rating too. Since I got a probe meter, I have found it very easy to send too much heat up your chimney with the hearthstone.

I'm surprised to hear that.

Me too, my old Homestead got up and cruised at 450-600 very easily.
 
Maybe it's our softwood? I have great secondary action, down to about 4 cords per year for a LONG burn season. Very minimal brown crunchy creo accumulation and plenty of heat. My chimney is only 14' though and all vertical. I don't need 550 but every so often I try and it is tough.

Now flue temps, those I can get hot.

Have you played with that pipe damper?

My chimney is taller, but even with soft wood I could get it over 550.

We need to swap flue thermometers next winter. Although I trust your reports, I don't believe those high temps are accurate.

Hehe, I've been waiting to hear this :)

My Mansfield can easily get to and maintain temps in the 550 - 575 range (stove top, center stone) whie maintaining proper exhaust temps. It is best to have both the probe and the stove top temps IMHO. That being said to the OP your dealer needs to be educated on these stoves, If I were not able to exceed 350, there would be no use having the stove at all.

I installed the damper onto my short chimney but it wouldn't seal to the stove. I knew it was not up to my standards for safety or for a tight seal (as every walrus loves). I discovered that Hearthstones are not compatible with the appliance adpater setup from Simpson but are meant to have the double wall shoved straight in.

I really would have liked to optimize the stove with that damper but it works okay as is. This might be a hearthstone thing. I recall every single hearthstone poster that actually has a probe meter reporting the same 750-800 running temps on these stoves. Pretty much double the surface temp. You cat guys obviously don't loose so much heat to the flue.

The final factor is that we all had verified a 10% error on the probe meters right? I will run up to 1100 with full confidence. I've even seen 1250 once on accident.
 
Calling Pen to the front desk..

IIRC the error was more like 20% at the upper end of the scale. I'd be happy to loan you my probe thermometer to do a comparison once the heating season gets going. It's hard to imagine that Hearthstone would design a stove that exceeds the continuous rating for the connector pipe.

I don't get that either. I have not noticed high flue temps on the Heritage.

Yep, that's the right neighborhood.
