: Is that 20TD with the gas valve on low or high input?
+++That was something I thought about after i posted. I believe with high output the DDT is 25. And after rechecking with just the one burner running, it looks like it is 10-15 DDT.
I assume I would want the 30 DDT to be with both burners going otherwise we would have the low flow condition in the dead of winter when both burners fire, right?
