Hi,
I have an old steam boiler that I want to install an electronic Low Water Cut Off into. Unfortunately there is no opening in the side of the boiler where the probe can go. The probe requires a 3/4" NPT tap which would require a 29/32" hole. I imagine I can carefully drill the hole in the side of one of the sections and then cut the threads. What type of drill bit should be used to do this? I know I would use cutting oil to keep it from building up heat while drilling. Should it be drilled in increments of increasing size? Not sure if this is a terrible idea or if there are alternatives to get my LWCO installed with some kind of remote setup.
The boiler is a 120,000 BTU natural gas Sears / Dunkirk that I believe was manufactured in 1979. Serial Number 7911104.
Suggestions appreciated.
Thanks!
