Hi Jason,
I have installed over 50 washer/dryers. Here is how I install the 4" vent. Try to locate the height of the vent the same as the outlet on the rear of the W/D. Try to keep the bends to a minimum. Once you find your desired location, draw a 4" circle on the inside wall of the coach. Plot out the location on the exterior and confirm that location is ok. Using a drill with a small drill bit, ( I use a 1/16" bit) drill a hole in the center going about 1/2" thru the interior wall panel. If you didn't hit any hidden wall beam, proceed drilling outward horizontally in 1" increments until you get to the circle you have drawn. Now repeat this process starting in the center going vertically up and down until you reach your circle. If you did not run into any beams, using a 4" hole saw, drill out the inside panel only. Pry out the inside panel and Styrofoam only. Using a 1/4 inch drill bit, drill thru the center of your hole to the outside. Using your 4" hole saw, go outside and drill the other 4" hole. Install the duct on the rear of the W/D and secure. Feed thru your 4" hole in the wall. install the W/D and secure. Pull the excess duct thru the hole and trim. I recommend using the chrome W/D vent that Splendide recommends. Part number VID403AC. Fred
