ILF250 mounting screws
The ILF250 installation kit includes a package with 8 1" screws and 3 1/2" screws. Figure 1. in the installation instructions appears to show long screws mounting the bracket to the fan body. It looks to me like those long screws would interfere with the fan impeller. Which screws in the installation kit should be used to mount the fan body to the bracket: the long ones, or the short ones?
Thank you for your question on the model ILF250 in-line exhaust fan. The small screws are used to connect the body of the fan to the mounting bracket. The longer screws are to be used to attach the mounting bracket to your joist.
