Re: New Rinnai boiler overheating very quickly but no hot water?
Yes, you need to supply and install a pump on the boiler loop, as per the installation manual. I don't see an internal pump?
Check your manual to confirm.

Shut it off and don't run it until you get the water flow issue resolved. 245 is way too hot.

Does your boiler have a built in pump? Quick google of diagrams show external primary pump.

Well… I believe I am looking at the correct manual. Where is the Boiler pump in your install ? It acts like there is no water flow through the boiler. No boiler pump (circulator) #11 below.

You’d be crazy to try to clean. 1966 tank.
The sludge is probably the last thing keeping the tank from leaking.

This is another case of "just because you can, doesn't necessarily mean you should".
Re: Steam device to be identified
You might actually have it- depends on what's inside the radiator valves.
