I am trying to assemble a Volvo MD2030 heat exchanger insert.
However, I don't know which direction the 2 large holes should be facing.
The manual says that the 2 large holes should face down and the 1 small hole should face up.
But, if the 2 large holes are facing down, they seem to be blocked by the housing wall. Is this correct?
