    Maybe I am being overly anal but when I follow the directions the probe seems too loose to me. I purchased a condar fluegard probe thermometer and drilled through both layers of the doublewall stovepipe with a 3/16" bit. Then enlarged the outer hole with a 1/4" drill bit. I slid the magnet onto the probe first and then the eyelet and put the probe into the stovepipe. I think the eyelet bottoms out on the inner layer of the double wall stovepipe, so I swapped the magnet and eyelet and it sits a lot better now.

    If it sits better the other way, then go for it.

    I went through the exact same scenario. But the instructions are clear to put the magnet on first, then the eyelet. I did have to jiggle the probe a little to get the eyelet to fit in well, but it does now. These kinds of thermometers are designed and calibrated to be used a certain way and at a certain height, so I figure that they have you do it that way for a reason. Just make sure that the eyelet fully goes into the 1/4" hole. It's a tight fit.

    Here's a hint. Try putting the eyelet into the 1/4" hole first and seat it. Then the assembly will fit into it.

    That is how I got mine to fit right.

    Just had another thought, do you have a full 1/2 inch between the inner and outer wall of the pipe ? that slip collar is close to a 1/2 inch long if I remember correctly. That would hold it out a little to far also.

    There is only 1/4" between the inner and outer wall of the pipe.

    What kind of double wall are you using? 1/4" is really close.

    That seems to be the issue with installing it according to the instructions in pic 4, that slip collar is made for 1/2 inch spaced double wall pipe. I dont know if this will mess with the temp reading accurately or not, might give condar a call or email.
    Mine works within 30 deg of the grill probe I have swapped back and forth with but my pipe walls have a 1/2 inch space also.

    I would do that. The outer surface of that pipe would probably be hotter than if the spacing were greater. If so, that would affect the calibration of the device.

    I emailed Condar with a question recently and got a very prompt reply.

    Well, I had a great correspondence with Condar and within a couple hours, they said they would send a shorter eyelet. Just waiting for it to arrive. Great customer service and very friendly. I would not hesitate recommending their products to anyone.
