Richmond gas hot water heater. After I light pilot and main burner why does it flame out in 15 seconds?


If you had to light the main burner manually, something is wrong. Once you light the pilot and it stays lit, the flame heats the thermocouple to open the gas valve and fire the main burner. Either or both of the components you replaced could be defective.

Water not hot even thermostate turned to high. The pilot light is on. Shoulder I be able to visualise the burner actually firing.,or hear it firing. I can see the pilot light clearly. Please help


If you have cold water now, you should hear the unit fire up and run while heating water. Proceedure would be; pilot is lit with thermostat at pilot setting. Once pilot is lit, you turn up to desired temp setting and you should hear the heater running. Depending on lighting, you should be able to see it slightly brighter and may flicker some while heating.

Gas hot water heater will not automatically heat water, i have to manually start the burner to heat the water


Sounds like you have a bad thermostat. You can change the thermostat, but if the heater is more than 8 or 10 years old you might be better off to replace the entire heater. Thermostat replacement is easy:
1 turn off the gas 2 drain the heater 3 unscrew pilot, main burner, and thermocouple lines from bottom of thermostat. 4 unhook gas line from thermostat. 5 unscrew thermostat from heater tank. Use pipe sealer when you install new thermostat, and gas line fittings. burner and thermocouple lines seal on a taper seat and do not need sealer. after reassembly check for leaks with soapy water, not a match, light the pilot and turn up the temp. The heater may sweat quite a bit while it is heating up the first time, this is due to the cold water on the inside and the fire on the outside. some water may drip in the bottom of the heater and you might think you have a leak, but let it heat up completly, if the water is still dripping after the tank is hot then you need to find the leak.

Hello,Don't worry about the rust flakes as every burner collects then and is normal.The new control should click.Please check incoming gas pressure supply 3.5"WC natural gas / 9"WC for LP.Check it at the piolt tube with a pressure dial meter,I assume the water temp now is cold.Did you change the thermocouple also as this provides the power to run the control?

The pilot assembly should look similar to the pic above. Depending on where you live, you may be required to hire a certified plumber to replace the parts. If not you can do it your self. Keep in mind if it's not staying lit you also need to check the thermostat and the thermocoupler before replacing the pilot assembly. There is a good chance it is just the thermocoupler going out. It is one of the first things to check when troubleshooting a pilot light problem with a gas water heater. A thermocouple determines if the pilot light is lit. If it's not lit, the gas valve fails. If that's the problem, replace the thermocouple.


  1. Shut off the gas valve on the water heater and the gas valve on the line near the heater. Remove outer and inner doors, and loosen the pilot and supply tubes and the thermocouple connections to remove the burner assembly.
  2. Step 2 Loosen the screw holding the thermocouple to the bracket. Remove old thermocouple. Bring it with you to the store to ensure you are buying the proper replacement.
  3. Step 3 Install the new thermocouple. Position the thermocouple so that the pilot flame heats 1/2 inch of the tip.
  4. Step 4 Reinstall burner assembly in the water heater. Tighten burner supply tube, pilot tube and thermocouple connections. Tighten thermocouple no more than a quarter turn more than hand-tight.
  5. Step 5 Turn on both gas valves. Check supply tube and pilot tube for leaks with soapy water. If soap bubbles, tighten connections to fix leak. Ignite the pilot light, and make sure the thermocouple tip is heating up. Replace inner and outer doors.
