from their site...
The L8148A,E,J Aquastat® Relays are immersion-type
controllers for use with forced hydronic heating systems.
The combination high limit and intermediate switching
relay works with a low voltage (24V) thermostat to control
burner and circulator circuits. A call for heat by the
thermostat starts both the burner and the circulator.
When boiler-water temperature exceeds the high-limit
settings, the burner circuit is broken; the circulator
continues to operate during the thermostat call for heat
you have the burner leads onto B1 /B2?
not onto C1/C2?

loosen whatever is securing the control to the thermometer well . slide the control out and check to see if the sensing bulb is fully inserted. if it is not in all the way it can not sense the water temperature so it will not shut down the burner.
sometimes a dab of grease on the bulb will help it slide in further.
