The installation of our LWZ 180 will be completed soon. Two flexible ducts were routed from the utility room to the attic. From there, the supply air duct is supposed to be routed through the soffit, and the exhaust air duct through the roof (via a metal collar that will be integrated into the roof and then fitted with the photographed cover).
According to the ventilation installer, the cover with a perforated grille will be installed perpendicular to the roof slope (meaning the grille faces upward toward the ridge and downward toward the eaves). I am concerned that rain might enter the exhaust shaft through the grille in the cover.
How should the penetration of the building envelope be executed? Are there standard solutions for this? Is fresh air intake through an outlet in the soffit acceptable?

Are you sure you understood correctly why not place the grille facing down? Because warm air wouldn’t be able to rise upwards as easily?The grille is installed on both sides (opposite sides).
