Grease duct cleanouts on horizontal sections of ducts should be spaced no more than how many feet apart?

The correct spacing for grease duct cleanouts on horizontal sections of ducts is set to ensure that maintenance and cleaning can be carried out effectively and safely. The requirement is for cleanouts to be spaced no more than 20 feet apart. This guideline helps prevent the accumulation of grease and ensures that access points for cleaning are readily available without requiring extensive rerouting or additional effort, ultimately contributing to fire safety and code compliance.

Cleanouts are essential in grease ducts because they allow for the removal of buildup that can pose a risk of fire if left unaddressed. The 20-foot maximum spacing strikes a balance between maintaining an efficient duct system and ensuring that it can be properly maintained to minimize hazards. By adhering to this standard, technicians and maintenance personnel can more efficiently address grease buildup, which is particularly important in commercial kitchens where grease-laden vapors are common.
