Hello All,
Photo 2 shows the damper that comes with the vent kit (it's hanging down). My fan only lifts it 1.5", and not the full 3.5" it would go to fully open the front of the vent. Is the plastic too heavy or the vent to weak? It is a 50cfm fan for a 35sq' bath. The duct length is very short (3' max with no turns other than where it comes out of the side of the unit and does a slow bend to vertical to hit the roof) Should I try a 70cfm, do something to the damper, or is this amount of opening acceptable?
TIA,
Molo
