Avalon Newport Convection Fan

[AvalonNewportUser]

Can't remove Convection Fan. Inner bracket is too large and attached by inaccessible screws. Photos on DropBox at https://www.dropbox.com/s/gi43poxn0leax0x/avalon convection fan.pdf?dl=0
Any suggestions?

Following up; no solutions to removal and replacement of complete fan assembly so had to take apart motor and fan on both original and Rotom replacement units to replace former with latter.
