Hood was damaged inner part, in which the engine was broken and had to be addressed and glued. Previously, the engine did not work (was blocked). The plate was bent upward, the Anschlüssrohre lacked the withdrawal. As our old hood was broken and we had a hole in the wall, and also because the hood was cheap, we have the self-repairing placed provisionally and not returned the goods. We have learned never returned goods !!!
