In telescoping and belt type connections, where should the inside ducts be positioned?

In telescoping and belt-type connections, positioning the inside ducts uphill of the duct section is crucial for effective drainage and to prevent the accumulation of grease and other flammable materials. By placing the ducts in this manner, any condensation or grease that might form is directed away from the connection points, reducing the risk of fire hazards.

This configuration supports the overall function of ventilation systems in commercial cooking operations where grease buildup is a significant concern. Proper duct positioning helps maintain the integrity of the ducting system and ensures that it operates efficiently, adhering to the standards outlined by NFPA 96 regarding fire safety in commercial kitchens.
