Our Aquaatar 125FX LP is 5 years old. I put in a rebuild kit in the water valve but the pilot light does not light the burner unless I turn the water on and off several times. There is plenty of propane in the tank What could be the problem?

    The problem is the intermittant operation of the flame sensor. The pilot lights every time but the flame sensor does not trigger the burner unless the water is turned on and off maybe three times. Suggestions?

Pilot tankless water heater utilizes Bosch's revolutionary hydro-generated ignition system incorporating hydro technology into a domestic water heating appliance. This new technology generates pilot spark from the flow of water eliminating the standing pilot light. The 125 HX LP (Liquid Propane) system ignites the burners when water is flowing without the need for electricity or batteries.

I turned on hot water to take a bath, and it was hot. by the time the tub had filled the water was freezing. now we cant seem to get hot water out of anywhere. the pilot light is on. the knob is set to on,...


if I was a betting may I would say that this is a small water heater, what is the temperature set on, as the pilot light will be lit once the temperature is reached, but until then the burners will be lit. I would move the temperature knob and listen to see if I hear the burners kick on. Hope this helps Tim

Do I need to replace the thermocoupling on my Reliance 501 gas water heater? Model is 5 30 NOMT7 C. Recently, I've noticed an intermittent problem with the the hot water not staying consistent. So we're...


The thermocouple is a safety for the gas valve. It tells it the pilot light is lit. If your pilot light is not going out and the burner fires when you turn up the thermostat, it is all working as it should. In other words, if you don't need to re-light the pilot, your thermocouple is OK. Turning up the temperature of the water is a good idea, just be careful not to burn anyone with the hotter water. You mite want to try a water saver shower head. Some don't throw enough water to get the soap off, but I bought one that can be turned to adjust flow and we have been happy with it. If I missed what you need from this, please let me know. Roger

I have a gas water heater, 6 years old. The pilot will lite and then the burner lites up, after several seconds the burner goes out. It won't stay lite. The other gas appliances are working. What's...


The Thermocouple, which is part of the ignition system may be loose, where it screws into the gas control valve. Or it needs replacing.

But, first turn the gas off to the water heater, allow the burner compartment to cool off and with a flash light do a visual inspection of the burner chamber. If you see rust or scale in the chamber or on the burner, it will need to be cleaned. You can use a wire brush to clean the burner, making sure you do it carefully and not too aggressively. Use a shop vac with a hose and crevice tool to remove the debris that was created when you cleaned the burner. Be sure to vacuum the burner ports well.

Look for the Thermocouple ... it will be in front of the pilot flame and look like a 2 to 3" long piece of copper. It will have a copper tube running from the bottom of it to the gas control valve. Does the Thermocouple look pitted and worn? Dos it have a hazy film on the tip? If so, use some very fine grit sand paper to polish the Thermocouple. You don't want to sand it, as much polish it. After you have completed that, use a cotton ball dipped in alcohol to wipe off the Thermocouple.

You remember the copper tubing I mentioned that runs from the Thermocouple to the Gas Control Valve? Trace that tuning to the control valve and see if you can loosen the connecting nut to the control valve with your fingers. If you can, it's loose and needs to be retightened. Finger tighten it and with an appropriately sized open end wrench tighten only 1/4 turn more. Turn the gas back on and light the pilot, following the lighting instructions on the water heater. Allow the control knob to remain in the pilot position for at least 1 minute before turning the control knob to ON.

The water in the tank has probably cooled enough that the burner should fire up. If it doesn't turn on the hot water side of faucet, to drain the tank some, so that the burner will fire.

Once it fires, take a stick match, light it then blow it out. Quickly place it next to the opening at the top of the tank where the Exhaust Vent Pipe is connected to the tank. If the vent is drawing properly, it should **** the smoke quickly up the vent pipe. If it doesn't, you'll need to check the vent pipe for obstructions or disconnections at the couplings along the pipe.

If the burner does not continue to operate properly after you have completed all of this. Replace the Thermocouple. Remove the one you now have and take it with you to a hardware or home improvement store, so that you can match it up to the ones that are available.

Hope all this solves your problem. Please let me know.

HOW TO CHANGE OVER FROM NATURAL GAS TO LP


There are some variations from one manufacturer to the other but basically they are all similar. If you have a gas valve that is convertiblble then normally there will be a screw plug cover on the gas valve where you can change the pressure for L.P. by removing the plug and spring and inserting a new spring to compensate for different gas pressures.You will need instructions for your unit as some require a specific number of turns on the plug to put proper tension on spring so gas pressure is right. On some units the burner orifices are adjustable on others you will need to change orifices on burners and pilot light.
If your gas valve is not convertable then you will need to get one that is. Hope this helps you. Thanks.

Carrier furnace burners will not light.if i blow at the burners it will light.I think maybe bad gas valve or not enough pressure


this sounds exactly like the problem. I replaced a gas valve yesterday in a Goodman furnace that had the same symptoms. I would check it or have it checked with a manometer before you replace the valve. If your inlet pressure is right and you cant get enough pressure by turning the adjustment screw clockwise, it is bad. LP should have @11-13inches of water column coming into the vavle and an outlet pressure of 7 inches of water column. Natural gas should have @5-7 inches coming in and an outlet pressure of 3.5 inches of water column

Furnace runs about 1 minute, then total shutdown


What type of gas supply line do you have? Is it black pipe or copper? If it is copper, there can be a film like substance that builds up on the inside of the copper. The debris will the get caught in a pre screen where the supply enters the valve thus cutting the supply of gas to the unit. Also, the thermocouple may be bad. You didn't say that you replaced it. Try replacing it as well. Also, you could have a limit switch turning the system off and thus cutting the gas off completely but it is highly unusual for the pilot to be cut off as well unless the pilot is being blown out when the gas is shut off. Also, turn the unit to fan only without calling for heat. Using a flame of some sort, put it into each baffle of the heat exchanger. If your flame is being blown around in one of the baffles, then you have a hole in the heat exchanger and what is happening is that the roll out switch is cutting the unit off and the air still moving through the heat exchanger is blowing the pilot out. I have seen this actually happen. If your furnace is in excess of 15 years old, it does need to be checked for possible holes. If it is in excess of 25 years old, it is a huge possibility that the unit has already developed a hole. If you feel hair coming out of one of the baffles, then shut the unit down immediately and have it replaced!

Rheem gas furnace pilot lights, but no burners or fan


If the burners do not fully ignite, the sensor will shut the furnace down. The lack of sufficient burner flame is a gas valve or gas pressure problem within the valve.
Replacing the gas valve with the original one may get you going. I surely suggest a professional service company for safety reasons and a thorough inspection. A 20 year old furnace is past it's normal life span.

Pilot ligting instructions


many of the newer furnaces don't have a standing pilot. look to see if you have a gas valve with a knob on top that says off pilot and on. look to see if a tube the size of a pencil comes out of the valve and goes down by one of the burners, look to see if there is a little gold piece of metal tubing protruding down to the opening of the larger tube . that is where you place the match. i prefer to use a grill lighter. safer and positive flame. turn knob to off wait 5 minutes for any gas to disipate. be sure your incoming gas valves are all open . usually at the meter and one at the furnace. usually the handle is in line with the pipe when open. from the off position, turn the knob on the furnace gas valve to pilot position and push down on it as you turn. this lets gas flow to the pilot tube by the burner where you have you flame starter lit and waiting. once pilot lights hold down on button for 3 minutes or less. longer is better to be sure the thermocouple senses flame . then gently release the downward pressure and the pilot should stay lit and you gently turn knob to on. if pilot goes out you may have a bad thermocouple. be especially careful if its lp or propane as that gas does not disipate like natural gas and can virtually lay on the floor till ignited. also consider having the heat exchanger checked by a pro with a carbon monoxide detector. they do crack after a few years and can be deadly when they do. good luck
