    Dear members : Welcome again,
    - I have stove model (Primus 96). When working more than 15 minutes, the tank is very hot, so you can not touch your hand more than 3 seconds,

    I think that's not normal, because I have two more of the same model. They do not heat up to this degree. Please help to find out the cause of the problem.
    Thank you.

    Do you have the stove enclosed?

    Along the lines of snwcmpr's Q, I'd add that the amount of fuel in the tank, perhaps the size and type of pot, air flow in the cooking area, etc, all may affect the rate that the tank warms up.
    That said, as long as you are using kerosene (by whatever name) and the stove is otherwise operating as it should, I'd not worry about it. I've have one that warmed up fast enough during the priming step that it self-pressurizes a bit (I like that).

    My Radius 20 and Primus 97 use to self pressurize when the tank is well filled, both get quite hot tanks in 10-15 minutes when cooking indoors - while they stay on a considerable lower temp even with the slightest breeze outdoors.
    Radius 21 get warm too but not that much - I guess it depends on a longer distance between tank and the hot part of the burner.

    Hi Optimust here, I notice the duration of the burning time 10 / 15mins is a common denominator. Can the heat be transfered to tank via the pot supports.
    Some are made with Aluminium. Just a thought. Best regards to All.

    Thank you all for your response

    But when the tow stoves run together ,So I can compare ,I find that one of them is much warmer,So I can not touch it , In the same operating conditions(The same type of fuel /The amount of fuel/weather/Runtime) just run. (Without putting any pot over it/without pot Support)( So I think the hottest There is something wrong!!

    Can you photograph both side by side?

    I wonder if both have mesh in the vaporizer.

    These photos are now.The stove that does not work is the hottest to shut it down.

    How is the fit of the bell to the vaporizer? Is one a tighter fit?

    I think the bell and the vaporizer is in its normal place and tightly, I have tried it many times..
    but now... I checked it again I have found that someone does not contain the ( lead washer) Which between the tank and lipstick ( nozzel) ,,
    -This is the reason for that heat...!!???
    - just guessing ?
    note: It works well without leaking...
    But the problem is in the heat...
    (Just heat)!!!?

    I would replace the lead washer.

    I'm on the way....
    When using a 96 I fully expect it to get pretty hot, and wouldn't be suprised at getting as hot as you say dependant on circumstances. Pot size etc.

    Sadly I've not used them to the extent that I have noticed a difference between various stoves to help much.

    I'm sure I remember previous comments regarding 96's getting quite hot in use, but given the extent of possible historical threads it may prove difficult to pinpoint an exact reference.

    I have a 96 to play with for the stove of the month and will let it run for 20 mins and see how hard I can push it with a big pot indoors.
