I am used to seeing a low-water cutoff for boilers, and it’s required by 2000 IRC M2002.2
I was recently helping a friend, who is an HVAC contractor, install a gas-fired hydronic boiler. He asked me if a low-water cutoff was still required. One did not come with the unit, and the installation instructions stated it was only required if the radiators were below the unit (not even shown on the installation piping diagrams). The boiler did have a built in high-temp shutoff.
Does anyone know if the thinking/requirements on boiler low-water cutoffs are changing?

I am absolutely amazed sometimes by how much thought goes into doing things wrong
