Not sure of anything, just putting it out there. Maybe you could make a telescoping flue out of 1" and 1.5" conduit. I know there are some issues using galvanized pipe for flue pipe, but you can burn and oxidize the zinc and make it safe. Think I might just start out my making a shelf for my Mr Heater in the middle of the cabinets at the 1' step level and lining the surrounding cabinets with metal and adding some doors. Kind of like this picture. I'm also thinking about a gravity feed stainless 3 gal water container, in place of tank and pump. Sorry the only props for a stove and water container I had were to resize a bbq smoker and a rain barrel.
