I have a shennandoah R-65 woodstove. I haven't used it in ten years and we have put it back in. Love the heat it puts out. Can we take out the bi-metal thermostat and somehow put in a regular manual damper? For the air intake on the front of the stove. If so explain how. Thanks so much. OK so now I'm thinking...Can't I just take out the bi-metal business and put in a simple metal strip about the same size so that I can still use the knob for adjusting the intake flap?
