I'm trying to install the gas line for this dryer. The instructions say the inlet pipe is male 3/8 inch. The female 3/8 inch line would not thread on. I went to hardware store. They said I needed an adapter that was 3/8 pipe thread female to thread on to dryer pipe with tapered 3/8 nipple for gas line. That didn't fit either. I bought a 1/2 - 3/8 adapter. it's too big....now what???!
