Fairly new Williamson by Weil McLain GWA-75 gas boiler that is turning off well before the aquastat high temperature set point. Another contactor condemned the temperature/LWCO probe - and we installed it at the clients request. Then we tested. Watch and educate yourself - as page 50 is missing from the manual!
