My WH started to leak so I bought a replacement. My concern is that the new one won't have the extra connector that the one in the pic has. It has a Tjernlund fan inducer attached to help exhaust the water heater through the chimney. I don't want to open the new WH if it has a different control valve than my old A.O. Smith had because I'm not sure how I would attach the Tjernlund control module.
So to break it down: the a.o. has the thermocoupler, main burner supply and pilot supply PLUS the extra connector - is that connector standard on all units?
