Question about Rinnai Water Heaters
The code that shows on the control is LC. what can I do?
Is there a chemical that I can flush through it?

Whiterussian is speaking without product knowledge. The first answer is correct, to follow the manufacturers instructions and flush with vinegar.
One of the most basic and simple things "professionals" miss is to always read and follow the instructions. They probably won't ask for directions when they're lost either.

Not really, commercial boilers are cleaned with concentrated surfuric acid which takes a trained professional with knowledge in organic chemistry to control that kind of dangerous reaction. CLR might remove some of the calcium deposits; but I have never tried using it. I usually buy a new heat exchanger and recycle the old one. Unfortunately without a water softener supplying the tankless it will just happen again; that's why in the fine print of your warranty it is void if you don't have a water softening system installed.
