I know a few people including myself have had their stove get wet inside/ outside after a rain fall which can be a pain to clean when you want to start a fresh session, or furthermore cause corrosion on the stove which can lead to prem breakdown. This idea will work only if you have a pergola like me or a roof surface.. if you dont, you can use a bucket 🪣 or something to put over your pipe. BUT make sure when you do cover your pipe that your stove and pipe have COOLED DOWN you dont want to cause a fire. Hope this helps.
