I have a Kenmore Elite gas dryer that is about 6 years old. Right now the dryer vent comes out the back of the dryer, but the exhaust has to make 2 90 degree turns before it goes into the outlet in the wall. At the bottom on the side there is an exhaust sized circle that looks like the exhaust could go out if the hole were punched out. Is this the case and if so, how hard would it be to do? This would eliminate one 90 degree turn in the exhaust and would allow me to push the dryer a couple of inches closer to the wall, which is an issue right now.
