Hello all. I use to be a swimming pool tech. many years ago and know something about gas heaters. A friend is about to get his 3rd Generator that I ordered online. I'm concerned if I just give it to him without ohm-ing everything out he'll just toast this one also.

So, can the system short out the millivolt generator and ruin it?

He took the book back to his house so I don't have the numbers here. Can someone give me a quick run down on what to look for and how TP , TC , and other things should be tested and how they work.

I just know he'll want to install it right away and not give me a chance to scan the book again and figure out what is wrong with this fireplace before we have another dead generator.

Thanks, part and labor are free for this guy.
