Dometic Tec Tower draught

[BusyBuilder]

On our Hymer B544, I have on occasion notice a draught coming through the vent on top of the oven (top of the Tec Tower). The oven vents through the roof.

I have had a look inside the vents on outside but it seems to be sealed around that area and doesn't look like its coming through there, but I may be wrong. I'm thinking of removing the top panel/vent above the fridge to see inside but it's quite tight and don't really want to damage it.

Any ideas ?

On ours there is a flexi stainless steel hose clamped to the top of the oven.
It goes into the roof vent but is not clamped to the vent. It is smaller diameter than the roof vent and slides up inside it.
So on a windy day its possible for a draught to come down through roof vent but we have not noticed it.
The cover panel above the oven has four plastic screw covers. Ease them off, remove screws and panel comes out.
Did find the sealant around vent had dried out due to heat from oven, we do use our oven!
Our van is 2012/13
