Description for Hydrolevel Safgard-550

Hydrolevel low water cut-offs are electrically operated. A probe is installed in the boiler shell or external manifold and is connected to the control unit. Water is used as a conductor to complete the circuit between the probe and the boiler shell. When water is in contact with the probe, the circuit is completed; when the water level drops below the probe, the circuit opens. Hydrolevel controls provide contacts to de-energize the burner circuit in a low water condition.

    Where do I wire in this control to an exsisting boiler that has no low water cut off now?

      It depends on what type of burner controller (flameguard) the boiler has. Typically you want it wired in series with the operating control (t-stat), Hi-limit and the Hi and Low gas pressure switches.
