Hi, I have been researching adding a baffle and a secondary air system to my Earth Stove 101 and was wondering if anybody has tackled this project on a similar stove. I think I’ll be able to figure out a design but this stove has a solid door so I’m a little unsure of how to tell if my secondary is working like it should after I get it installed. This stove is around a 1987 model I believe. It was originally bought by my grandfather and used in his house for many years before we got it. Thanks, Kyle
