Is that the setting of the weight on the baro itself or is that the reading on a manometer?
That's the reading on the manometer.
Also is a manometer a worthwhile investment. I would like to burn my stove as efficient as possible and it sounds to me that a manometer is the way to go. Any advice welcome and Thanks
If you invest in one then you will always have it to know exactly where your draft is and it'll always be there if you ever need to readjust your baro. For 35 bucks brand new at a store it's going to give you the most effieciancy out of your stove.
