Where must grease duct reservoirs be located?

Grease duct reservoirs must be located on the bottom of the horizontal duct or duct riser to effectively collect and contain grease that may accumulate during kitchen operations. This positioning helps prevent grease from dripping back into the ductwork, which could pose a fire hazard and create blockages.

By situating the reservoirs at the bottom, there is also gravity's assistance in gathering any grease residue that might settle. This design feature aids in maintenance and ensures that the grease can be removed more efficiently, thereby promoting a safer and more functional kitchen environment. Proper drainage and access for cleaning are critical in maintaining compliance with safety codes, and placing the reservoirs at the bottom streamlines these processes. Overall, this design reduces the risk of grease buildup in the ductwork, enhances fire safety, and supports system longevity.
