Weil-McLain CGa series 2 LWCO Electrical connection

Hey everyone,

Happy holidays. I have just gotten a new Weil-McLain CGa series2 gas heater and because it's new and the Electrical board has been prefixed, I dont know where to connect the wires for the McDonnell & Miller 24V LWCO and the emergency stop device with temperature control.

I have called their tech and he told me the incoming (which is 120V) so I said thanks but no thanks.

this is a 24v lwco and because I have previous experience (10+ years with CGa 3) I am lost with this new device.

I have the original manual and it has nothing on lwco and emergency switch off device.

this is for NYC plumbing regulations
