    Are you saying it was never getting hot enough to close the door?

    Did it keep the house warm?

    When it's cold out and the boiler is running hard, the boiler won't ever get hot enough for the door to shut. And you will burn more wood as a result. During really cold weather, I don't think mine shut very often, either, as I recall. You really notice it with wet or green firewood. The moisture in the firebox sends a lot of your heat right up the stack in the form of steam, and the boiler never gets up to the setpoint. You burn more wood that way, too.

    Did you ever put a damper in that thing, danzig? I'm telling you, man, it's a good thing to have even if you never use it. If you have too much draft (possibly due to the wind), then a lot of your heat is going to head right up the stack unless you control the draft by damping it down. Also, as I mentioned in an earlier post, make sure that the stainless steel baffle that sits on top of those two water pipes in the top of the firebox is pushed all the way back to the rear of the boiler. If not, it will let too much heat go.....well, you know where.

    Depending on how high you have it set, it sure should be closed at those temps. Check the chain. It might have become tangled, which would prevent the door from closing all the way. Sometimes those links can get crosswise and even though it's hard to see, it can cause problems. The door should close when you turn the knob on the Ammark counter clockwise. If not, then you've got a mechanical problem with the door or its hinge that you need to fix to avoid overheating the boiler.
