Best Answer

it heats up the thermo couple which opens up the gas control valve allowing gas to flow to the main burner. if the pilot goes out the thrmo couple will cool and shut the gas valve so gas does not come out

Have you turned the control from Pilot to On? Have you increased the temperature setting?


When the pilot light cut off from the water heater for 2 days do you have to run water for it to reheat?

If the pilot light is on, the heater should come on by itself. If the pilot light is off then it has to be lit. If it will not stay on, the thermocouple is bad.


How do you light the pilot on a 10 year old Teledyne Lars LLG pool heater with an electronic spark?

You don't. If the heater has an electronic spark, then it doesn't have a standing pilot to light. The spark lights the pilot when there is a call for heat, which in turn lights the burners. If the heater is on and the pump is RUNNING, the heater should light automatically when the water temperature is lower than the heat setting.


What is wrong if your pilot light will not stay lite?

High winds, pilot generator. Is the heater located next to a wall? Is the heater door closed? Does the heater have a draft hood or what they call a stackless heater? Ken
