Vokera Compact 29 HE won't ignite without the case cover seal removed....?

To get the fan out to clean the venturi, you just need to unscrew the flue hood on top of the burner and slide that out with the fan attached to it. Only need to slide it out about 3-4 inches to be able to get at the venturi. No need for a drain down and no way were you ever going to get at those screws under the fan in the flue hood with it still in place.

Im pretty sure we tried every possible combination, probably except this lol
Vokeras instructions about fan removal were very poorly written so cheers for the heads up
