I have 1” black iron pipe running just shy of 40’ to a manifold. The manifold then has one run of csst coming off it to my furnace. I then have 4 more ports I can run off for new appliances as I convert them to gas. My electric dryer just went up I would like to replace it with gas. The run would be about 30’. Is 1/2” csst big enough for that run the dryer is about 22000 btu. Thanks in advance.
I concur, 1/2 inch gas pipe is adequate for the dryer. The only thing I would like to add Is, did the gas company run a 2 psi meter to your home? an easy way to tell is if there is a gas regulator at each appliance. This is a pretty common practice in the state I live in. If it is a 2lbs system, you'll need to have a regulator added to the new appliance. Just something to be aware of.
