What are the Clearance Distances Required for Indoor Oil Storage Tanks?
I would say the nearest is approximately 5 feet away from the burner which I personally still regard as too close. Hence, at home you would have to see for yourself what is the distance that you feel is safe enough to prevent any fire hazards from occurring. I still think 10 feet is a better option but it entirely just boils down to the whole setup you currently have.
For fire safety indoor oil storage tanks should not be located too close to oil burners or other heaters. Typical indoor clearance requirements specify that the oil storage tank should be 10 feet from the oil burner. Some communities permit the oil tank to be located closer, just 5 feet away from the nearest oil burner. You can see this design in our sketch at left, provided courtesy of Carson Dunlop. If you cannot meet this distance requirement your local building officials or fire officials may approve the oil tank installation if you provide a fire barrier between the oil tank and the burner. Tanks should also be located where they will not be damaged, such as by being struck by a vehicle entering a garage. In some communities indoor oil storage tanks located in a garage must be protected against possible vehicle damage by steel posts or similar means. In some communities indoor oil storage tanks must also be secured against possibly falling or tipping over, such as by using angled
