low water cut-off

I want to install a LWCO (none on it now) on my Weil Mclain CGa spark piloted boiler, but unsure as to using a 24v or 120v type. What would I need to be considering to decide which one to order? Any brand recommendation?

    Curious, what boiler/mechanical inspector allowed this install without one.

    LWCO

    There are plenty of places where LWCO's are not required on residential jobs.

    Both 120 volt and 24volt accomplish the same thing. Unless code dictates, use whichever is easier for your install.

    that scares me, residential should have the same or tighter code requiements in your area

    It depends

    Does a mod/com located in a basement need one? You generally have a water pressure safety. Supply and return sensor plus a high limit on the boiler and a T&P.

    Is that enough?
