Came out today to replace warranty parts. After repair further diagnostics were needed. Upon inspection I found a faulty external low water cut off. The new Weil-McLain boilers have them built in. I wired the system back to its factory settings and called for heat. The system started right without any issues. I observed the system hitting the temperature limit and shut down. There is no need for an external low water cut off since it is built in. The system is operating properly at this time. No charge part of install.
