Interior Power Vent Enclosure

The exhaust blower assembly consists of a blower and
damper constructed into a single box. This assembly is
best placed in a location where it can be accessed from
all sides (ceiling plenum, utility closet, mechanical chase,
attic space, service corridor, etc.). It is imperative that
the assembly be placed in a location where the vent
connections and junction box may be accessed.

If you do wish to enclose the blower assembly, make sure
to place it in a location where it may be accessed and the
vent and wiring disconnected for servicing. The
illustration below details the minimum clearances required
for the exhaust blower enclosure. Make sure to include
an access door on the side that has the junction box.
This will allow a service person to access to the junction
box and vent connections.
Interior Power Vent - Attaching Vent to the Blower Assembly

When attaching the vent to the blower assembly, make sure to accommodate servicing at a later time.

Attach a male adapter to both the intake and exhaust (e.g.: Duravent 8GVAM). When attaching make sure to
orient the adapter correctly (note direction of flow). For the exhaust, the adapter will be sealed and screwed
to the exhaust box.

After the male adapter, use an adjustable length connector on both the intake and exhaust (e.g. Duravent
8GV12A). Make sure to position the connector so the tensioner may be loosened after the installation is
complete. This arrangement allows for the adjustable lengths to be loosened at a later time and the vent
connections detached from the exhaust blower assembly.
