Commercial buildings have duct systems that transport air outside or inside of the building. An HVAC system usually brings in natural air from the outside to cool or warm it, depending on the weather. For establishments with kitchens, the smoke needs to go out through the ducts.
However, these ducts will get dirty over time because of the dust, debris, and bacteria, so you have to hire duct cleaners to remove them. One way to make their jobs easier is by installing duct access doors to enter hard-to-reach areas. If you plan on installing one for your duct system, you have to learn its installation and application basics.
The Importance of Installing Duct Access Doors in Commercial Buildings
Without duct access doors in your commercial building, you’re going against the NFPA 96 Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations. Most preferably, the NFPA 96 talks about the importance of installing duct access doors in all commercial kitchen exhaust systems. Installing effective equipment in your commercial building can significantly reduce potential fire hazards.
The NFPA 96 states that vertical and horizontal ducts must provide access, with horizontal ducts having at least a 20” x 20” opening. If you cannot provide that opening size, you must create a larger one at 12 feet intervals to provide thorough cleaning.
Also, duct access doors must have the same thickness and material as the duct, usually an 18-gauge stainless steel or 16-gauge carbon steel. Each duct access door must be grease-tight and have a seal or gasket with a 1,500°F rating. Your contractors need to use stainless or carbon steel fasteners, and they should not go through the duct wall.
Hopefully, the things mentioned above will teach you how contractors install them and the importance of duct access doors for a commercial building.
