Guys am just finishing off a garage @ that abutts my house. The lean to roof of the garage covers where my flu used exit so the boiler needs to be reloacated....also it will free up much needed space in my already tiny kitchen! So im moving the boiler into my garage. I have 2 questions. 1. Is there any reason against putting the boiler in the "attic" area of my garage?(there wont be a ceiling in the garage but there will be boards here and there on the joists for storage etc..ie it wont be an enclosed attic.) 2.What distance am i required to leave between my flu and the soffit? Many thanks, Marty.
