The bottom of a grease duct reservoir must slope towards what?

The bottom of a grease duct reservoir must slope towards a drain to ensure that any accumulated grease and liquid can effectively flow out of the duct system. This design is critical for preventing the buildup of grease, which can pose a fire hazard. Additionally, proper drainage helps maintain hygiene in commercial cooking establishments, reducing the risk of grease-related issues.

Sufficient sloping ensures that grease and other residues do not remain stagnant in the reservoir, facilitating easier cleaning and maintenance. This is especially important in environments like restaurants where grease ducts are frequently subjected to heavy use. By directing the flow towards a designated drain, it allows for the safe and efficient disposal of potentially hazardous materials, thus adhering to safety codes and standards.
