    Are the hinges on the door adjusted? Does it leak at just one spot? (if so where) Does it only leak with the fan on, or all the time?

    Have not adjusted hinges only latch.
    Leaks on the top and left side, only leaks when fan is on.

    I didn't find any info on hinge adjustment in the manual, so I don't know if they are adjustable. You will have to look and see if there are adjustments. You can also do a paper test to see if the door is tight. I noticed you have another thread asking about cleaning the boiler tubes. If you have a blocked tube you could have a lot of air pressure in the boiler, and it has to go somewhere. The door seal is the weakest point. I would recommend getting the tubes clean, and see if the problem goes away.

    There is build up in the tubes i pull out the inserts they were hard to get out so i think this might be the problem? Build up all on the sides. By cleaning these tubes should help?

    Yes if you get the tubes down to bare metal, or as clean as you can. It should stop that issue. You should clean them weekly until you get a feel for how dirty they get, this will also increase efficiency. I would also guess you are burning wood that is not dry enough yet.

    If you trap a piece paper in the door, it will tell you how good the seal is by how hard it is to pull out the piece of paper. Like a feeler gauge for the door seal.

    I would guess the issue is the blocked tubes.
