Adjust? What do you mean? The flame relationship to the T-couple? Or is the flame too low?
Low flame can be adjusted on some gas valves but mostly it requires special tools and knowledge of the gas valve. Most times it's a sign the GV is going.

New thermocouple on GE/rheem water heater pilot still won't lite


does the pilot go out when you let off the button? Or does the pilot not light at all?

If you dont get any gas at all to the pilot the the gas valve is bad.
Of you get a pilot light that goes out when you let go of the button then the therno couple is not reading the flame (needs adjustment so the pilot flame touches it)
did you kink the new thermocouple? or over tighten it at the gas valve.
if it was kinked its now toast,cant straighten them. If kinked and starightened the fluid inside has broken the inner seal and wont work.

Hello. I have a Bosch WR-430. It has been working well until recently. (6 years). A few days ago, I noticed that the pilot was not lighting everytime. The spark would spark, but the pilot would not...


Hi, Please do massive / longer bleed on/off for several time and get it retry. If problem still persist, I worry you have problem on your controller and need repairing at dealer.

Regards, Jay

Adjust pilot light on hot water heater


On most water heaters there is no adjustment to pilot light. About the best you can do is clean pilot and burner. If you are having trouble keeping pilot light lit then I would replace the termocouple.

Pilot keeps going out after it cycles a few times


Hot water heaters that have problems with pilot lights going out are usually fixed by adjusting or replacing the thermocouple. The thermocouple is the brass tube that is in or near the flame of the pilot light. The thermocouple acts as a valve to allow the gas to flow to the pilot light. If the thermocouple begins to go bad, it may shut the gas flow off to the pilot light. There could be other gas supply issues, but this is about the least expensive first step for the home owner. REMEMBER, you are working with gas. Take your time and be safe or have a professional replace the thermocouple.

Atwood gas waterheater with white rodgers gas valve pilot hard to light and not a big enough flame to touch the thermocouple


I think you need to reposition the thermocouple, or adjust the pilot gas pressure by adjusting the pilot screw make sure it is still the recommended gas pressure of the system... please contact a HVAC tech if this things did not work.

Pilot light on boiler


The plumbers repair should be guaranteed, give him a call back.
It sounds to me that the pilot flame needs to be adjusted or the thermocouple is not aligned properly or there is a draft that is blowing out the pilot.
Good luck...

Lighting the pilot light


The steps involved can vary slightly depending on your furnace model and pilot valve type, so if possible try and find the instructions inside the furnace door cover or in the instruction manual. This is for a gas fired furnace, but applies to any gas-fueled appliance including water heater. Two of the most common types of pilot valve body assemblies either have a red reset button and a gas valve or no reset button and a valve knob that can be depressed. But whichever type you've got, if you have an older model furnace with a standing pilot (flame is lit all the time) then this is the basic procedure.
  • Turn you thermostat to 80 degrees or to a setting that will demand heat. Make sure the thermostat is in "Heat" mode.
  • Go to the furnace and find the pilot valve. The pilot valve body is a box shaped device into which the main gas line will run and is located near the gas burners. It will usually have a gas **** or valve knob that reads "On, "Pilot" and "Off." Locate this gas **** or knob.
  • Turn the knob or gas **** to the "Off" position and wait about 3 minutes for any residual gas to clear away.
  • Find the pilot. It's located near the gas burner tube assembly in the furnace.
  • Get your match or lighter ready. Sometimes the pilot is hard to reach. If possible, try and use a long fireplace match when you light it. If you don't have a fireplace match then a butane BBQ grill lighter works well too. If you don't have that, then you can fasten a match to the end of a stick when you light the pilot
  • If you have a pilot with a red Reset button, turn the gas valve from "Off," to "Pilot."
  • If you have a pilot with no red button, turn the knob from "Off" to "Pilot."
  • Place the lit match or ignited lighter tip at the pilot and depress and hold the button or depress the knob as appropriate. Depress the button or knob for about 30 seconds. This maintains gas flow to the pilot until the thermocouple gets hot enough to open the main gas valve.
  • Once the pilot stays lit, slowly release the button or knob and turn the gas **** or knob from the "Pilot" position to the "On" position. This will ignite the burners and keep the flow of gas supplied as required for the burners as called for by the thermostat.
  • If the burners fail to ignite then it may be because the thermocouple did not get hot enough to open the gas valve. Wait a few minutes and then repeat the above procedure. This time hold the red reset button or depress the knob for about 45-60 seconds.
  • Once the main furnace burners ignite, adjust the thermostat to the desired setting.
  • If you've followed the previous steps on lighting the pilot and it still does not light after, or will not stay lit, then you probably have a problem with the thermocouple or an adjustment needs to be made to the pilot. You'll need a furnace service technician to replace or repair these parts. You may find that the pilot lights, but it is an anemic looking flame. That's a different problem we'll look at in the next section.
  • If the pilot lights but the flame is a weak yellow flame, it will not get hot enough to heat the thermocouple to its set point allowing the gas valve to open.
    A natural gas flame should be a bright blue with the tip of the flame having just a tinge of yellow. A propane flame should have a bluish green flame with a tinge of yellow at the tip. The flame should be strong enough to hit the thermocouple tip about 1/2 inch from the tip end. If the flame is weak or shaky looking, check to see that a breeze or draft is not blowing on it. Adjusting the Flame
    There is usually a small screw on the pilot valve body that will adjust the flame. You may have to refer to the manufacturer's instructions to find the screw. Turn the screw as needed to adjust the flame throw. Yellow Flame
    A yellow flame is caused by lack of air and incomplete combustion. It can be caused by a dirty pilot tube tip. Split Flame
    This is caused by dirt in the pilot tube. Take a needle or small nail and gently clean the tube. Flickering or Wavering Flame
    A flame that flickers is usually caused by a draft.
