Old vigilant flap noise issue

[jas0nlev1n]

hi all! I have a 1975 Vermont Casting Vigilant in my house, it's fantastic, been hearing the house in New England all winter for five years now with it very successfully.

Only issue is the thermostat at the back: when the stove gets right about to temp (where is set it, so that then lap has just closed), it starts flapping around open and shut. Really annoying. It lasts until there's a change in temperature (room starts to cool down) or until out of frustration I yank the switch one way or the other (which ruins the point of a thermostat). It's not puffing smoke as others have discussed (though that has happened maybe once a season.) It's only moving like a quarter inch each time, every second or so, so it sounds like Chinese water torture.

Any suggestions on what in doing wrong, or what I can do so it stops flapping around? Thanks in advance! Jason

It's a common problem. I solved this on our Resolute by affixing a tiny magnet at the edge of the flapper. That made it close positively until the thermostat called for heat. Worked like a charm.

I hear that on my Vigilant occasionally. Usually, just the tiniest but of change in the 'stat setting will get it to stop. Either lessen the tension on the chain or tighten it just a wee bit.
