We're in our second season burning pur Green Mountain 60 and obviously still getting a good feel for it. Among other things (like actually getting a full 8-10 hour overnight burn) I find myself wondering how important it is to keep the catalyst gauge at a consistent level or if it doesn't really matter as long as it's in the active range? If it is important to keep it consistent, any advice on doing this? Apologies if this has been discussed before.
