Hooking dryer up to exhaust outlet

I have read that a dryer should not be hooked up to a flexible hose since it is a fire hazard due to dryer fluff collecting in the hose. This leaves you with the steel or aluminium piping. The issue is how to connect the silly thing to the back of the dryer and the hole in the pipe that comes in from the outside when the holes a different heights.

I there some trick to this aside from having to be a double-jointed acrobat to try to get these things aligned, taped and/or connected with a metal tightener?

Not quite sure what your issue is. I have a dryer hooked up to rigid galvanized steel piping, with two bends before it exits outside through the sill beam. Attaching was very simple, I simply purchased two adjustable bends which can be rotated in three dimensions. They have standard couplings to 4 inch galvanized pipe, which is push fit, followed by taping with aluminum tape (no screws which can attract lint). One of the bends goes on the outlet from the dryer, and one goes in about three feet from the outdoor exit. I put the pieces together one at a time, and adjusted the bends to make the fit work correctly. Certainly it would have been much more difficult, maybe impossible, to make my setup work with rigid ninety degree bends.

There''s nothing wrong with a flexable line, just do not use the cheap plastic or foil type.

As said already, the transition duct (in dryer room only) or hose needs to be metal flex it has to terminate there, less than 8' long; fig. 60;http://www.codecheck.com/cc/ccimages...6th_Sample.pdf

The periscopes are very bad because they restrict air-flow, IMO use the metal flex, short as possible to a rigid metal duct;

More info for you; http://www.ashireporter.org/HomeInsp...st-Systems/161

17,000 dryer fires a year, when did you last clean the inside of the dryer near motor or the exhaust ducting?

Dryer fires are no joke nobody is trying to scare the public with bs it is a fact. If you dont think so check with your local fire station for the facts and figures or just google it. Dryer fires happen with freqency.

Here's a video showing the different air flow rates of various vent designs. Some can make the dryer work harder while others make it more efficient.
