I’ve got a 2H that is going to replace my H. Can anyone help me on the picture below? The pipe circled in blue goes to the water pump. I’m assuming that this would go to my heater. Then I have 2 coming out of the head circled in red. What are these for? Where do they attach to? I’m assuming one might be the other side of the heater? If so what is the 3rd one for. Thanks!
