What is the purpose of providing cleanout openings in grease ducts?

The inclusion of cleanout openings in grease ducts primarily serves to facilitate maintenance. Grease ducts are part of kitchen exhaust systems where cooking grease can accumulate over time. This buildup can not only obstruct airflow but also pose a fire hazard if left unchecked. By providing cleanout openings, maintenance personnel can easily access the interior of the ducts to remove accumulated grease and debris, ensuring the system operates efficiently and safely.

Regular maintenance through these cleanouts helps maintain the functionality of the grease duct, reduces the risk of fire, and prolongs the lifespan of the system. Other purposes, such as structural support or aesthetics, are not the primary concerns addressed by the provision of cleanout openings, nor do they directly relate to the operational integrity of grease ducts.
