By reading the directions provided with the heater
The older types of water heaters have a gas controller that has on top there is a button called pilot and you must turn the adjusting knob to pilot then hold the button down , light the pilot tube located just below the thermo couple HOLD it down for TWO minutes (enough time to heat the thermo couple) then release and make sure the pilot stays lit.. Then turn the dial to ON and adjust the temperature
On the newer models there is an sparker and you should read the directions supplied with each type of heater .
YOU should also find out WHY THE PILOT LIGHT WENT OUT as sown drafts can be quite dangerous
The gas water heater pilot light may not stay lit due to a faulty thermocouple, a clogged pilot orifice, insufficient gas flow, or a draft near the pilot light.
A water heater pilot light typically uses about 3-5 cubic feet of gas per day.
The pilot light on the water heater went out because there was a lack of gas flow or a problem with the ignition system.
The water heater pilot can go out due to issues such as a faulty thermocouple, a dirty pilot light, or a lack of gas supply.
There are several possible reasons why your gas water heater pilot light keeps going out. It could be due to a faulty thermocouple, a dirty or clogged pilot light orifice, a draft in the area where the water heater is located, or a problem with the gas supply. It is recommended to have a professional technician inspect and repair the water heater to determine the exact cause of the issue.
The most common reasons for a gas water heater pilot light to go out include a faulty thermocouple, a dirty pilot light orifice, a draft in the area, or a gas supply issue. It's important to have a professional inspect and repair the issue to ensure safe operation of the water heater.
Gas water heater has an orifice for main burner and for pilot light, if not electronic ignition.
The water heater pilot light may not stay on due to issues with the thermocouple, gas supply, or a dirty pilot light. It is important to check and potentially replace the thermocouple, ensure proper gas flow, and clean the pilot light to resolve the issue.
The water heater pilot light may not stay lit due to issues with the thermocouple, gas supply, or ventilation. These problems can prevent the pilot light from staying lit, leading to the water heater not functioning properly.
To turn on the pilot light for your water heater, locate the pilot light assembly near the bottom of the water heater. Turn the gas control knob to the "pilot" setting and hold it down. While holding the knob down, use a long lighter to ignite the pilot light. Once the pilot light is lit, continue holding the knob down for about 30 seconds before releasing it. If the pilot light stays lit, turn the gas control knob to the "on" position to start the water heater.
No because water heaters have a safety valves and when the pilot light goes out the safety valve shuts off the gas
The water heater pilot light may keep going out due to issues with the thermocouple, a draft in the area, or a problem with the gas supply.
