When connecting an oil filter to copper piping smaller than 3/4", what is required if it is not directly connected to the oil tank or burner?

The requirement for rigidly supporting an oil filter connected to copper piping smaller than 3/4" stems from the need to ensure stability and prevent stress on the piping system. When the filter is not directly connected to the oil tank or burner, it becomes crucial to provide additional support to avoid any potential movement or vibrations that could lead to leaks or damage.

Copper piping, especially when smaller in diameter, can be prone to bending and unsteady connections if not properly supported. Rigid supports, such as brackets, ensure that the filter remains in a stable position, thereby minimizing the risk of strain on the joints and connections. This support also contributes to the overall safety and proper functioning of the oil fuel system by maintaining consistent flow and reducing the potential for wear over time.

While insulation, flexibility, or manual valves may have their own roles in different contexts related to oil fuel systems, in this specific scenario, the focus is on maintaining the integrity and rigidity of the connection to prevent issues that may arise from a lack of support.
