We recently purchased a 1982 C30 and the alcohol cooktop has been replaced with a propane one. But it still has the original alcohol oven and there was no operating manual with it. On the back of the unit is a metal line kinda like a brake fluid line, that was not attached to anything. We took the whole unit out and brought it home to clean it and figure out how to use it. Can anyone tell us HOW to use this oven. Where does the alcohol fuel come from? Surely that tub doesn't just sit down in an open container of alcohol. <http://personal.lig.bellsouth.net/lig/h/e/herr1174/backofstove.jpg>Back of unit <http://personal.lig.bellsouth.net/lig/h/e/herr1174/frontofstove.jpg>Front View Thanks!
