Product review (1 stars): Install nightmare
Purchased a LG DLE4870W at Lowes Home Improvement.  I chose to vent the dryer out the left (as you're facing it), side.  Called LG and they gave the the part number for the vent kit and when I called their parts supplier, they said it would be five days before I got the package.  Chose to go to Amazon and entered the part number and this came up.  Promised two day arrival, so I bought it.  The Lowes installer and I worked for about 90 minutes to make this thing work and still could not get it vented correctly.  Here's the problem...After coming off the back pipe with the angle, the next straight pipe that should reach the side is about an inch too short.  IT WILL REACH IF YOU WANT IT TO GO TO THE RIGHT, BUT NOT THE LEFT.  The reason we spent so long trying to make this work is that we cut the original pipe the dryer came with to rig it and still could not make it work.  We gave up as it was after hours and just ran the flex pipe off the angle INSIDE the dryer.  Lame...  He left and I called LG.  The guy in Bombay told me that it was my fault for not going through their parts dealer.  Really?  Okay, didn't want to wait and I'm being punished.  Called Amazon and they gave me a refund on the spot.  THANK YOU AMAZON, I LOVE YOU!  Went to Lowes and got a new pipe for free and vented out the back and now I'm wiser about how to not vent a dryer.  BTW, the parts in this package are so overpriced that I can't begin to understand the reason.  If you HAVE to side vent it then buy a short piece at Lowes to connect into the dryer, buy an angle and then some flex duct.  You'll spend twenty bucks instead of seventy.  Buy some aluminum tape for the joint at the angle.  Don't use duct tape, it will fail.  Hope this helps.
