Slightly off topic, but what about whole house fans & Attic fans?
Do you cut them in, or do you just wire them if someone else installs them?

"How many Electricians among us install the venting for Dryers and Exhaust Fans?"
We do it when asked. Not too often, but I've done quite a few of them over the years.

When I was doing residential, we supplied bathroom exhaust fans, nailed them in place and wired them. After this the Mech contractor vented them. We only provided wiring on all other fans. Bill, I still use the plastic venting from Dryer to rough in. (I hope thats OK ) Roger

Bill, I still use the plastic venting from Dryer to rough in. (I hope thats OK ) Roger, I've seen that Metal seems to be recommended or required on newer Dryers. I had a Customer tell me a couple of years ago that it was a code, after I did them a 'favor' putting in 50 feet of plastic when they asked, and after the walls were sheetrocked. Bill

Roger,
I didn't get paid to put it in and didn't even want to.
I don't know if it was in any code or not. The house passed all of it's inspections without anything being mentioned, and I've seen Plastic used quite a bit. I think that they read something in the directions when they bought a New Dryer that set them off.
I said I would replace it as a favor, but that they would have to get the wall patched. Long story short - they weren't happy. I learned a lesson

1998 IMC 504.6: "Exhaust ducts for domestic clothes dryers shall have a smooth interior finish..."
2000 IMC 504.6: "Exhaust ducts for domestic clothes dryers shall be constructed of metal and shall have a smooth interior finish...."
2000 IRC M1501.1: "Exhaust ducts shall be constructed of minimum 0.016-inch-thick rigid metal ducts having smooth interior surfaces...."
As far as the I-codes are concerned, the requirement for metal seems to have come in with the 2000 editions. The IRC is more restrictive than the IMC.
Note that all of these also allow the section of flex connector between the dryer and the duct proper.

Anyone here know what NY State codes said about plastic/metal venting prior to recent adoption of the International codes?

I'll install the venting if it doesn't involve too much heavy building work, e.g. a bathroom exhaust fan which just entails cutting a hole in the ceiling and exterior soffit for the grilles.
I won't get involved with knocking holes and patching brick work for fans, and will suggest that I supply the fan (if requested) and that the customer has a GC do the necessary fitting and patching work.
