Does anybody what is commonly required for venting a fan/light/heater combo in a bathroom ceiling?

Usually two or three inch pipe to daylight. Shortest route is best. Can go to roof but easier if straight out through the floor/ceiling joists

Does it need to be single wall metal pipe or insulated?
I've never installed one with heat strips in it before.
If all else fails I can call city on monday.

I don’t believe it requires anything special. I’m sure the instructions say to check local codes. Not sure they make double wall pipe that small.

exhaust fans are 3". 4" or 6" , not a lot of 3" anymore and the 6" seem to be more than 4". makes for less sones ( noise) .
being heater you may have to use aluminum pipe.

I used 4" flex insulated duct. Think I had to run it ~20' to get to the gable end of the house but it works great. I did notice the unit is a bit louder than it was with no ducting as I imagine the flex creates some back pressure. If I had it to do over I would use hard duct as much as I could then use some flex on each end.
Either way, the broan unit I bought produces less than half the noise the 1972 unit did and it removes all steam in the bathroom.
Add a timer for the fan and you'll wonder what life was like before you had the timer.

If your running it in a non insulated space make sure you use insulated duct. If you dont the hot humid air in the pipe will condense on the cold pipe and drip or fill with water.
