    Not sure that this a good or bad idea.
    Something needs to open to relief the pressure. If not, the pressure will look for the next weakest point and maybe do some more severe damage.

    In Austria/Germany they install a device in the chimney near the boiler that has an "explosion cover"
    It is typically integrated in the barometric damper T.
    The explosion cover is spring loaded.
    So it releases the pressure and then closes again.
    This all happens in a fraction of a second.
    I will see that I can find a picture.

    Also, in Europe (Italy), many pellet boilers have a similar spring loaded cover integrated in the boiler body to prevent this when pellet ignition failed and lots of wood gas is present in the fire box and suddenly ignites.

    Good points there.. Obviously something needs to be done as what is there now is not acceptable.. What happens pretty much sounds like a backpuff which my CDW stove was notorious..

    Thanks. I have no idea why the photos are repeated, I uploaded just two. Sorry about that. Would you know how to correct?

    Some pictures of an explosion cover integrated in a barometric damper.

    The reason the door blows open is because it's pressure on a flat surface.
    If the door does not open, then the pressure will most likely act on the next weaker flat surface; boiler water jacket, .... .

    Storage also eliminates idling, which can help keep your fire tubes from accumulating creosote (less tube punching). :)
