Need help with fitting the roof vent!

[darcyvuqua]

So the first greenhouse up and the second frame up but looking at the first one the roof vent does not look right and upon opening it does not feel right

The destructions are very vague does anyone know of and info or videos online I can see a roof vent being fitted onto a eden halls 8x6 greenhouse

Thanks in advance
