No heat in 2 zones

I have three zones on my boiler, two that go to the main floor, and one that goes upstairs. One on the main floor is working and the other two are not. I went down to the boiler, all zones are on and receiving water. The pipes are hot to touch coming off the zone but then quickly become cooler and cooler the farther away you get. I have tried tapping on the connections on the pipe and that has not seem to work.

boiler brand: dunkirk
temp is currently 176 on the boiler

thanks for any help!!!!!

Welcome to the forums.

It sounds like two zones are airbound. You may have to bleed them zone by zone.
If you aren't sure how to do that..... post a few pictures of your setup there.
