Anyone have any luck or knowledge regarding Auto Draft controls being added to a Fisher? Is there still a source for these and are they reliable and worth using? Now that I have two newer style Grandpa Bear stoves, I would like to get a fire going in each and have the luxury of not having to tend them if I am away. The idea of choosing your desired temperature and now having to keep playing with the damper is nice. I burn mostly red fir as I have a grove of it out yonder. Good and hot burning.
