Piazetta sabrina convection fan.

[Ravippe]

Another quick question. Pascal Martins posted a quick post on replacement of a convection fan for piazetta sabrina .He said all you do is remove the screws, wiggle the fan and put the new one in. In the event next 2-3 years if i need to replace my convection fan can somebody show me where the screws are? Do i remove the left panel siding or right panel siding to access the motor? I guess im having trouble understanding where the screws hold the fan to the unit and how to easily unscrew and what to remove to access it. Last year i vaccummed all the dust bunnies but didnt notice how it attached. I attached a pic, maybe you could circle where screw goes?
