Timothy W Cambridge , MA March 20, 2016 Appliance: Model LG DLGX3571W Lg dryer needed side venting LG has several instructional videos on Youtube which are very easy to follow. The knockout plate was not so easy to knock out. The piece on my dryer was spot-welded about 8 places around the circle so it took some effort to remove it. Make sure the side vent extends 1.75" out from the side of the dryer. I left less extending on mine since I have very tight clearance, which made the pipe susceptible to sliding inside the dryer and making it difficult to slide the next section of ductwork onto it. 14 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
