DRYER VENT
INSTALLATION GUIDELINES
CAUTION! Dryer vents have sharp edges. Use gloves to prevent injury. When working with power
tools, gloves and eye protection are absolutely required.
These installation guidelines are for use with typical or standard applications. It is always recommended to seek advice from a licensed professional,
and to check with your local building inspector or building permit office for approvals and possible variations that may apply.
Dryer Vent Guidelines
Building Codes usually require that dryer ducting be no longer
than 25 feet. Subtract 2 1/2 feet for every 45° bend and 5 feet for
every 90° bend.
Ducts should be smooth metal with a minimum diameter of 4
inches. Flexible ducts can collect lint, be crushed, and potentially
start a lint fire. The ducts should not have screws or connectors,
which can collect lint.
The overlapping ends of the duct should face the direction of the
airflow. The duct exhaust must not mix with other systems such
as the cold air return plenum.
The dryer exhaust duct should vent to the outside, and the vent
should be at least three feet from any other opening. The vent
should have a damper to keep vermin out of the home. There
should not be a screen over the opening, since it could trap lint
and cause a fire.
1) Drill a 3/8" hole from the inside to locate the position of the
dryer vent. Note: your dryer vent should be at least 3 feet away
from the nearest window or door. Cut a 4 1/4" diameter hole with
a hole saw.
2) Apply a bead of caulking around the hole then insert the dryer
vent (DV4). Affix the vent with 4 screws through the flange.
3) Assemble 4" ducting from the vent to the dryer exhaust port.
Secure each component joint (ducting, elbows) with metal foil
tape; do not use screws as they will trap lint. Support the ducting
by securing it to joists or studs with Plumber's Tape (pipe strap).
