I have a Reliance 606 natural gas water heater. It is 8 years old. The pilot light went out on it and I replaced it. I lit the heater and waited 30 minutes to check the water temperature. The bottom of the tank is very hot and the bottom of the tank is cool. Water temperature is warm but not hot. What can I do?

1) Bad gas control thermostat, or thermostat has come out of calibration, or water leak running hot water out of tank.
Turn up temperature.
Replace gas control valve.

2) Clean air intake, put ear against pipes and listen for water leak, check that flame is clear blue and that combustion gasses are flowing up the vent pipe and not blocked.
3) Call service technician.
