Dryer gas line coiled

Hello,
I recently purchased a house. The dryer had a ton of lint in it so I decided to replace the dryer vent. I noticed that the copper gas line is very long and coiled and makes it so I cannot put a rigid vent on the dryer. The copper tube pulls the yellow line too far. Is it normal for the copper tube to be long and coiled like this or should I have someone come in to shorten it? (Note: the flexible vent on the dryer now is just temporary to keep bugs from coming in the house; the dryer is not being used until it is replaced with something more durable.)

I assume when you say rigid that you are referring to the
Semi-Rigid Dryer Duct.

Secondly I would suggest using an elbow at the dryer rather than trying to make the 90 degree turn with the duct.

Not sure why they left all that excess copper piping except maybe to allow the option to move the unit further.
I don't see a problem with leaving the copper tubing and simply moving it slightly, as required.

Thank you for replying! Yes, I did mean semi-rigid, and I also used an elbow from the dryer. As long as the extra copper piping isn’t an issue, I’ll just leave it as is. I just had never seen that much behind a dryer.

Why don't you get a 1/2 flex gas line. That's the normal behind a dryer or range. Measure from your valve to the
inlet of the dryer and then add a little. Usually a 36" or 48" works fine.

It appears in the picture that it already has a flex line. The copper tubing is upstream of the isolation valve. ???

Let me guess, you’re on a propane system? The higher pressure of propane makes the 3/8 gas line adequate. I remember the old days, I’d have to dig to find my flaring tool.

I was just looking at the copper line and didn't even notice that flex line. If your not going to use the copper line
then I would eliminate it. Put a cap or plug on the end of the valve.

I believe that's what the yellow flex line is connected.

You are correct!!!!!!
