What is one requirement for oil-burning equipment according to NFPA 31?

One of the key requirements for oil-burning equipment according to NFPA 31 is that chimneys must meet certain height requirements. This is important because the height of the chimney affects the venting of combustion gases, ensuring that they are properly dispersed away from the building and any nearby structures. Adequate chimney height helps to create effective draft, which is essential for the efficient operation of the oil-burning appliance and for minimizing the risk of backdraft or the accumulation of harmful gases within the living space.

Proper chimney height is also crucial for preventing obstruction by nearby trees, buildings, or other features that could impede proper venting. Therefore, adhering to these height requirements ensures compliance with safety standards designed to protect both the occupants of the building and the appliance itself.
