Just finished the cycle pilot conversion to HSI on my Weil McLain. Every thing went great and boiler lites better than ever now. Now get ready to install a Tekmar set back.

Was the kit provided by WM. I don't see a flame sensor at the end opposite the igniter.0

They do not require a flame sensor on that unit...0

The igniter is doing the sensing in addition to igniting the gas. Those have worked out very well as a replacement for the troublesome Cycle Pilot Systems. They were a problem from day one.
I might add here that technicians can't use HSI or DSI as a replacement for any pilot operated systems. This one is okay because it was determined as a retrofit by the OEM not the service company.
Even when we install a Intermittent pilot retrofit it must be authorized by a cross reference from the control company whose retrofit you are using.0 -
I don't like the fact that the igniter acts as flame sensor. The sensor should be at the opposite end in case you don't get carry over to the last burner.0
