A puff back loss occurs when an oil burner backfires sending soot throughout one’s home.
It can happen all at once or gradually, slowly seeping out.
The best way to prevent a puff back?
Have your oil burner inspected annually and kept in good shape.
This is no guarantee that you won’t still have a puff back loss, but it does greatly reduce your risk.
Keep debris or anything else that could interfere with proper functioning away from your oil burner.
