I have a 17 year old hot water heater. I had to replace the thermocouple. Upon re-assembly, there is a sliding collar that can be adjusted to control how much air is mixed with the gas and thus controls the strength of the flame.
2 questions: 1 - how do you know when the collar is in the optimal position ? do you adjust based on flame color or flame height ? 2 - since the repair, i have a mild natural gas odor (maybe a bit stronger than mild) that exists when the hot water heater burner is running. it can be smelled throughout a good part of the house - any thoughts ?- posted
