Good day! We appreciate your interest in our Metal-Fab 6TGC. Yes, this can be used for an oil furnace. However, due to the nature of your question and the potential to cause damage, injury, and even death by the misapplication of chimney products, I believe you should contact a licensed and bonded professional contractor. It is imperative to follow everything that is written in the Installation and Maintenance Instructions. Should you have any more questions, please let us know.
