I bought EGAN camping wood stove last December with the regular pipe setup. It was good but I had creosote issue because intense rain weather and everyday stove usage, so I bought additional pipe adapter. I use adapter to turn pipes upside down to avoid creosote build up, as well I bought chimney rain cap and it's perfect now! All issues of rain weather are sorted and I would strongly recommend it! This little pipe part brought stove performance to the new level! Happy customer :)
