For my application I had to get into my attic to replace the ventilation adapter. Getting in the attic is not always necessary to replace the adapter but my fan was attached to the truss in the attic.

The bathroom vent uses this adapter to connect an 4\" exhaust hose to the unit. Our adapter was missing (probably mistakenly discarded over the years). The adapter has a \"check\" valve, or blast gate which closes when the fan is off ... to prevent back flow in from the outside. This gate/valve closes using gravity. When the fan is on

The adapter has pins that fit into notches on the vent\'s case. The only way the adapter would fit was upside-down, which cause the gate to be open when the fan was off. I eventually removed the gate, and reversed it.
