Education

FREE Training For Your Group or Organization

We’re on a mission to educate and inform as many people as we can about the reality and dangers of dryer fires and how to quickly and affordably prevent them. Do you belong to a group or organization that looks for interesting speakers from time to time? Our goal is to educate and not sell.  We provide free informational sessions for Civic Groups, Church Groups, Mom’s Groups, Non-Profits, or any group interested in a speaker with a fire safety/energy savings message.

 Dryer Vent Terminology

Dryer Exhaust System- The dryer exhaust system, also referred to as the dryer vent, is the combination of pipes, elbows and termination cap which carriers moist air and lint away from the dryer to a point away from the dryer.

Developed Length of Vent – The developed length of the vent pipe is the sum of the length of straight pipe + 5 feet for every 90 degree elbow + 2.5 feet for every 45 degree elbow. The developed length of the dryer vent system should be less than 25 feet.

Dryer Vent Cover – Typically used as a horizantal termination point, vent covers are normally white or brown and have louvered flaps.

Duct Pipe – Same as vent pipe, building codes specify that the duct inside walls be rigid metal pipe and should not be flexible. No flexible pipe should be used at any point hidden from sight. Ducts should be connected to each other using aluminum tape and not by screws.

Elbows 45 Degree and 90 Degree – These are found in most dryer vent exhaust systems and allow the vent to be angled to reach the termination point through the roof or side wall of the structure. Too many elbows decrease the efficiency of the dryer vent system and should be avoided.

Transition Duct or Transition Tube – The hose of pipe that is connected to the clothes dryer at one end and to the dryer vent system on the other end This duct should be made out of non-flammable material such as aluminum and can be flexible. This transition duct should be as short as possible, less than 4 feet if possible. This will help to prevent the transition duct from getting crushed behind the dryer restricting airflow. This will also help to lessen the buildup of lint in the duct.

Termination Point – Point at which the dryer vent system ends, should be at the exterior of the structure. The termination point is typically at the roof or side wall of the structure.  It should not be in the attic, garage or any other enclosed space.

Rotary Brush – The method of choice for cleaning most dryer vents. The brush travels the entire length of the dryer vent releasing lint from inside the exhaust pipe.

Dryer Lint Trap – Collects a large portion of the lint your dryer produces. Should be cleaned before or after each load. Dryer sheets create an invisible film on the lint trap reducing airflow and dryer efficiency. If dryer sheets are regularly used, the lint trap should be scrubbed gently with a brush and mild detergent every couple of months.

Dryer Vent Kit – A dryer vent kit consitsts of two elbows and about 3 feet of corrugated, semi-rigid 4″ metal piping. Both elbows should be of the swivel type to allow for proper installation.

Dryer Vent Clamp – Used to connect the dryer vent transition tube to the dryer and the vent. Usually made of stainless steel.

Digital Anemometer – A device used to measure airflow. At Extreme Clean, we always take an airflow reading before and after a cleaning.

Carbon Monoxide – If you have a gas dryer, a clean dryer vent is especially important. A lint clogged or obstructed dryer vent or transition tube can cause carbon monoxide to be vented into your home.
