STANDARD OFFSET CONNECTIONS
Using 4-inch heavy metal vent:
NOTE: Do not secure exhaust vent joints
with screws. Screws can catch lint and
slow the drying process. Instead, use
clamps to secure exhaust vent joints.
STEP 1. Install a 4-inch metal elbow on
the hood and on the dryer exhaust outlet.
STEP 2. Measure the length of 4-inch
metal vent needed to connect the two
elbows.

The vent usually comes in 2-foot lengths.
Use tin snips to cut the vent 3 inches
longer than your measurement in order
to make a connection.
STEP 3. Place a clamp on each end of
vent elbow and connect elbow to dryer
outlet. Tape the joint with duct tape.
