A more delicate and sophisticated method is to slip a crescent wrench over the keeper, adjusted so there is no play, then bend it in slightly.titleist1 wrote:The Mark III has the same door latch. I have on occasion used a hammer to bang in the keeper on the stove body so the door latch is drawn to the stove body more tightly.
But as I said above, the gasket will again compress to compensate, and within a week or so there will be virtually no resistance when you latch the door. The gasket is wide enough that it still makes an adequate seal. Just make sure the spinners on the loading door are VERY close to completely closed, especially with the high draft that you must have from a 20' chimney and wide-open MPD.
