    Just because you say that is some sort of fact doesn't make it so.

    Current industry standards as well as UL recomendations state that rigid metal or semi-rigid metal ducting to be used. These METALS include aluminum and galvy.

    It is not recommended to use the white plastic or foil ( Mylar with metal coating).

    http://en.wikipedia.org/wiki/Messiah...(self-concept))

    "Messiah complex is a state in which the individual believes themselves to be, or destined to become, the saviour of the particular field, a group, an event, a time period, or in an extreme scenario, the world. This could also be the state in which a group views an individual as a messiah, such as followers of a cult leader. The cult leader doesn't have to claim to be a messiah, but if he is treated as such by his followers, it can also be classified as such.

    Messiah Complex may also refer to a person who has formed a habit of "creating" crisis in a given culture, only to later "rescue" or "save" the poor helpless soul upon whom the crisis has been perpetrated."

The flapper works fine, the venting is not clogged. On cold days when the dryer door is opened it is like a refrigerator door opening. I have no doubt that the cold air is coming from the outside and the basement. Would indulsting the vent duct in the basment and adding another flapper at the start of the vent duct behind the dryer be of any help, or just a waste of time? Suggestions appreciated.
    Just about everybody knows you have to isolate Aluminum from masonry, mortar, concrete/cement, etc. when exposed to air and moisture it will soon corrode.

    NFPA 54 (adopted by many states, and many localities) has since the 2002 edition RESTRICTED ducting for Type 1 Clothes Driers to RIGID duct only. prior to that semi-rigid was permitted (1999). Clearances unless otherwise specified are 6 inches from combustible materials. Other building codes are NOT MUTE on this subject as well (clothes dryer vents, concealed, connected to GAS (not electric) CLOTHES DRYERS.

    Other model codes and locally written codes, as well as local ammendments to model codes further direct and restrict.

    The Original Poster has indicated the vent runs down a wall, then UNDER the floor in unheated basement before transitioning to outdoors. I have yet to have seen a wooden or non-masonry non-cement basement. Now if the Original Poster wants to be specific as to manufacturer, model and serial number, type of GAS (LP, nautral gas) and specific as to location, and which codes are in effect in his/her jurisdiction, can refer to case specific. Have already referred to local building office/local rules, and the manufacturer's guide.

    Caught spouting off and making erroneous statements that cannot be backed up, the usual offenders begin personal attacks and continue to make outlandish and unsupported claims. This is their pattern.

    Obviously ****hiller who claims many clients and claims to be adept in every building trade as a provider - yeah right, will start the attacks when he claims an organization sanctioned something they didn't and claimed authority via indirect and unrelated websites. Probably has no clue that the CPSC has also warned against using any spring, spiral, coil type venting for any clothes dryer, not just gas ones for quite some time as well. The organization he claimed endorsed the use use of flexible aluminum vent/duct for gas clothes driers has not, and was one of the lobbying efforts to specifically disallow its use. The efforts were sucessful, and now in most model codes it is specifically prohibited, as are semi rigid vent/duct materials now.

    That an OLD article from the TOH site not written or demonstrated by a tradesman but instead a former writer doesn't surprise me. Reader's Digest, TOH on-line, and your other vague references used by havanagranite (a supposed former drywall hanger and now supposed countertop fabricator) and canuk (who claims his dad or grandfather was a carpenter but has never represented he is or has ever been licensed to do anything) might suggest anything doesn't matter in the least. These coiled vents and semi rigid materials are sold for various purposes, there is nothing that prevents their marketing or sale, only their IMPROPER USE OR INSTALLATION. One can walk into any big box and see for example toilet flush valves side by side one labeled "anti syphon" and one NOT labeled anti syphon - both legal to sell, only one legal to install.

    The standards for such appliances, and their safety listings include their listed instructions. These specifications and instructions must be followed.

    To the original poster, I suggest you check the internals of your dryer for lint collections. You should also check your vent hood for lint collections, as well as the entire vent. Perhaps you have the wrong type. You describe two to four turns (wall to down under floor, vertical to horizontal to under floor, up and out to vent hood - one, two or three turns).

    If you have other fuel fired appliances such as water heater, boiler, furnace in the same area perhaps they are air starved and using your dryer vent as an air source. Normally the damper at the vent hood should remain closed when the dryer is not in use, if it does not, and you are experiencing a WIND, then there is a problem, it is up to you to determine what that is and to what extent it can be compensated for.

    Just because you can buy aluminum doesn't mean it is appropriate to use in your application. Quite a few DIYers as well as "contractors" who are not licensed to do this type of work, as well as the "installers, delivery agent sub contractors" that show up from home centers will use these type of materials. The aluminum rigid ducting for your bathroom exaust vent is not for your gas clothes dryer. The "thickness" of what may be used under some codes for gas clothes dryer is thicker, but still shouldn't be used where in contact with mortar, masonry, cement, concrete, etc.

    To anyone who is following this "discussion" (I use the term very loosely)......and doesn't understand/know how to overcome the aluminum to concrete/masonry supposed "dilemma/crisis" - You simply sleeve the aluminum pipe where it passes thru the masonry with a material that is compatible with both the aluminum and the masonry......and is adequately heat resistant for the temps that the pipe will encounter while serving as an exhaust flue for either a gas or an electric dryer.
    (This is a clothes dryer, not a 100,000 BTU 80% furnace or boiler)


    Or you can "spot shim" the pipe on the inside and outside of the wall so that the aluminum itself is not in direct contact with the masonry. Then use an appropriate heat-resistant caulk to seal the perimeter around the pipe.

    Pretty dang simple stuff.

    you want to shoot down others credentials to try to make it sound like others don't know what they are talking about yet you freely admit that your only experience is google. tell me how that makes sense to you. explain how your google gives more weight to what you say then the experience of ones in the trade. here is a heads up. you are quoting from unknowns, anyone can have a website, and anyone can put anything on a website it doesn't make it factual yet you are picking and quoting websites as ultimate authority with out even the most basic knowledge that a first year apprentice would have. if you had half the knowledge that you claim you would be a lot more silent on this board. there is a saying its better to be thought a fool then to open your mouth and remove all doubt. and you remove all doubt every day on this board.

    havanagranite,

    You try to put words on me but they are not mine. They are your own invention.

    You are beyond rude. You cannot support any of your assertions. I can and have . Your misrepresentations and disingenous assertions about me are untrue. Frankly you are a liar.

    you haven't proved anything other than being able to do cut and paste. your rude, obnoxious and have no useable knowledge. your only value would be the person in the carnival who works at the dunking booth insults people to get them to spend their money and you do the same here trying to get people to waste their time reading your 10 page posts. people don't want cut and paste messages nor that done on google search they could do that themselves. they want first hand experience which you don't have. you need to find a computer forum where you can put your skills to work, it isn't here and quite frankly I'm rather tired of seeing your sig at all. I'm sorry you were picked on so bad in school and that your husband left you. but that isn't our problem get over it.
