During the exhaust cleaning service your Up-Blast fan has to be tilted back in order to access the vertical duct of the system. If the exhaust fan is not equipped with a hinge kit, the fan has to be lifted off the duct curbing and laid to the side on the roof top. The fan is made of a pliable spun aluminum that is easily damaged. Over time continued service can cause damage to the fan, causing it to be replaced. At Hood Boss we highly recommend that code* is followed and a hinge kit is installed to protect your equipment. There are different types of hinge kits that can be installed at different prices to fit any budget.
Hinge Kit Installation
Quick-Fit Econo Super Hinge
The patented Quick Fit Econo Super Hinge™ provides access to rooftop up-blast exhaust fans and is perfect for the smaller fans on the market. Designed specifically for smaller up-blast exhaust fans with a total weight of less than 25 pounds. The Econo Super Hinge™ features the Quick Fit mounting system that allows users to install this version while the fan is still running. Hinged up-blast exhaust fans are required for commercial exhaust systems to be NFPA 96 compliant. The NFPA 96 requirements state the following code for hinging compliance:
