How to install bottom venting dryer

Moister in the dryer:

This means that the moist air is not escaping correctly and that is why it is taking so long to dry your clothes - if they dry at all.
a good start at cleaning out lint blocked areas, I suggest go to the back of the dryer and take off the vent pipe or hose and check things out with a flashlight. Clean out all the lint and dust you can, even use a vacuum cleaner on it. Make sure the vent pipe is completely clear of any obstructions.Non-rigid ventshas much worse air flow than smooth piping, so you might want to upgrade tosmooth piping.
Once you have all the lint and dust cleaned out of the dryer, go to where the dryer vents outside. Again, clean the area thoroughly. There is usually a trap door that opens when the dryer air is on and closes when it is not operating. It should be completely clear of lint and opening smoothly.
Also, look into the exhaust area on the dryer carefully to see if there is a hole or gap in the dryer's internal air ducting. Without the vent pipe connected and with no clothes in the dryer, start it and let if run for a few seconds and make sure there is strong air flow from the exhaust port. You should feel it strongly on your hand.
Re-connect the vent pipe and start the dryer again. Feel all around the bottom to see if any air is blowing out from under the bottom. This would indicate there is a break or gap in the dryer's internal ducting. If you do feel air, you will need to call a service technician to see if it can be repaired. If your dryer is very old, there could be a rust hole in the duct.
In conclusion Cause ·Poor venting is a common reason why water might leak into a clothes dryer. Since the dryer works to expel moisture, it is important that the dryer's vents are properly installed so that the humidity can escape.
Effect ·If the humidity in the dryer is trapped, it will eventually turn to water. This will lead to poor drying results or longer drying times, depending on the amount of leakage.
Prevention/Solution ·Faulty dryer venting can be prevented by making sure that the humidity is directed outdoors. Also, vents should be cleaned of lint and other debris before each load so that water can readily escape. Taking these precautions can ensure that the moisture will meet dry, open air.

There should be a "knock out" on the bottom of your dryer, but there would also involve some reconfiguration of the internal vent duct.

The vent pipe codes are based on the fact that the blower in a typical gas dryer can only 'push' a certain volume of air through a certain sized duct for a certain number of feet. Reduced volume of airflow means higher temperatures thus higher risk of fire.
First option ... is your dryer anywhere near a side wall, which would allow you to shorten the total length of duct required to reach the outside to something less than the 14 ft code limit ?
Second option ... upsize the standard 4" dryer exhaust duct to 6" to compensate for the 30ft length
Either way, in the absence of an external forced draft booster fan ( a.k.a. 'power vent' fan ) you should be using metal exhaust duct not plastic.

Check the vent cap on the outside of your home to see what the air flow is like when the machine is on. It should be forceful enough to blow your haire back if you were to put your face in front of it. Make sure the vent hose behind the dryer is as short as possible and is not pinched or coiled. This definitely sounds like an air flow issue.

Hi. You have a venting issue. The moist air is not getting out of the dryer and is building up inside the venting. Look behind the unit and make sure the vent is not crimped or crushed, probably best just to replace the venting. As well, you may need to have the duct from the wall to the outside cleaned by a duct service. I'd replace the flexible duct from the dryer to the wall first (you can get this at a hardware store, 4" dryer flex duct) and then run the dryer and go outside to see if you feel any air coming out of the exterior vent. If not, then have someone out to clean it. Good luck, hope this helps.

most likely your vent line is plugged up with lint and dust,make sure the outside vent is clear and if the vent line is long blow it out with a leaf blower and check the duct that the lint filter slides into,if that's not it call the factory if it's only 3 weeks old,let me know what you find

It's not the temperature of the air that is the problem. The air is seldom over 160 Deg F. If you have a vent fire the piping needs to last long enough without melting to starve the fire of oxygen in the hopes of extinguishing. Rigid aluminum piping is best suited for this, Rigid flexible is next. The tin foil and white plastic offer little resistance to melting if a fire should begin. The melting would allow the fire to replenish oxygen and support the burning process. The main caution here is to keep your dryer and vent clean...at least annually.

If the duct inside your wall is rigid metal all the way from the dryer to the house exit you need to do nothing to it . Replace the vent between the dryer and the wall with rigid metal 4" piping or hard flexible aluminum piping. If the duct inside your wall is either of the least effective types you need a new run of vent for the dryer to avoid a fire.

You can't use white plastic or flimsy flexible aluminum that feels like aluminum foil when you touch it.

I would suggest you try this simple easyfact finding venture:
remove the vent fromt he dryer(take a bucket as the vent is going to have water in it) pour the water out of the vent,leave the vent off and try drying some loads,IF the unit works as it should( normal dry times) then you will need to have the vent cleaned to the outside. many birds like to place nests in them!
Good Luck!!

Many home improvement stores such as Home Depot , Lowes etc carry Vent kits. I would encourage you to pick up one of these and install it through your outside wall. Normally, the outside portion of the vent has a flapper to keep outside air and critters from coming into your house when that vent is not in use and also has a short section of ( typically) 4 inch vent line that projects through the wall cavity and into the living space. Most flex lines should be atteched to that. If you are usintg a gas dryer, it is strongly encouraged and may be code requirements in some areas to use only solid ducting to the outside. Electric Dryers do not have the same exhaust gases and can be ducted with a plastic flex line. Hope that helps...

take the vent hose out of your dryer and try to dry the clothes, if it works your dryer is fine and the vent is clogged
