Yes, you do. I believe my Reddy heater instructions had a chart telling how much fresh air was needed depending on the size of heater and area being heated. Our two car garage is insulated with drywall so the door or window needs to be open several inches to be safe with it running continously.Originally posted by simple_john
Im running a kerosene heater in my garage.. its nice and toasty....
I can smell the kerosene fumes.. not horrible... but i was wondering.. is there a need to keep a window cracked or anything to allow ventilatinn in the garage?
