Installing a Gas Dryer

[Peter76]

Hi Guys
I got a job to install a Whirlpool Gas Dryer, I need to run a pipe/tube almost 12 m, am I allowed to use copper? am I allowed to use CSST?
Thanks

You can use cooper or CSST as the branch line then use a gas flex connector to make the final connection.  If you use CSST follow the manufacturer's installation guide as it's more stringent than the gas code.  You may need to protect the CSST and install additional upstream bonding.
