Hello. I'm at the beginning of burning season and trying to make sure my thermometer gauge is correctly calibrated for our Ashford 30. Most of the photos I've seen here are with a different gauge than what I have (mine is about 1 year old). At room temp the needle is below the Inactive zone a small amount, photo below:

Should I be adjusting it so the needle is at the bottom of the Inactive zone, or leave it as-is?

Thank you very much!

My Princess 29 insert thermostat looks like this when cold (no fire), room temp is 62F:

I'm guessing that's not right.

Stove was installed professionally in Feb 2023 and I believe the thermostat has always looked like that. Should I adjust it? I scanned the user manual and didn't see anything about what the cold thermostat should look like. I did see the forum threads that indicate that this is not correctly calibrated.

You are correct, this meter needs to be calibrated. Pretty crappy that they can't just hold a zero like most any other thermometer.

WHen cold, the red needle should point to the very bottom of the inactive range.

Thank you, appreciate your reply! I did contact BK this morning via their website, and they replied to assure me that I haven't damaged my stove and sent the following instructions:

"The needle should be pointed at the first “tick” mark below the Active range. Adjusting them can be a bit tricky so you may want to have your dealer help. There are two nuts, one on top and the other on the bottom. If you ever so gently loosen the lower nut, you should be able to turn just the face of the thermostat slowly (counter clockwise) to reference the needle to the first tick mark."

Thank you to this forum to bringing it to my attention!

Well, it's actually that first tick at the bottom of the INACTIVE range which coincides with the bottom of the inactive scale.

If you break the meter during adjustment, or if you find the set point wanders, you can buy a better made condar brand cat meter with actual numbers to replace it. I have 4 different mechanical condar meters and none have ever required resetting the zero point.
 
Lol, I still wonder if BK is laughing behind the scenes when they read that ^^ because they just rebranded Condar thermometers...

BTW, the first tickmark below the Active range is the one that's also at the bottom of the inactive range.

Condar might make the meter for BK, might not. I don’t recall that being announced. Whoever makes the BK cat meter certainly appears to produce the part at a lower quality level than what you can get direct from condar.

More likely that these are cheap China clone thermometers.
