If there is nowhere else to locate one, you might even be able to replace your manual air inlet knob with a bimetallic unit at the same location.
Yeah, I've looked at doing that.. Overall though, basically a bimetallic unit would do exactly what my barometric damper already does. The baro keeps heat output flat by keeping the negative pressure in the furnace consistent. Thanks for your suggestion
