Replaced thermal coupal pilot light burns then burner comes on burns for 15 seconds both go out?
Make sure the thermal couple is postioned in the pilot flame correctly. It could be a bad gas control valve.
Is it possible for a pilot generator to become weak and only open a 750MV gas valve partially to give the burner a low flame output?
The way I understand it ... no. The pilot generator is a thermally sensitive on/off switch. It simply tells the valve to open or close. If the unit turns on and fires it would seem the pilot generator has worked correctly. Since the amount of gas flow is the issue, it would seem the gas valve is the culprit and is not opening all the way. Of course, to be certain have a pro check it. If you must, a pilot generator is cheap and easy to replace without a professional, and replacement would quickly determine if the pilot generator was at fault.
What happens to the flame size when the gas control valve is turned?
adjusts the size
How do you convert a fireplace from propane to natural gas?
Get a certified technician to work on gas. He will have to change the orifice, possibly the gas valve.
What should you do if your gas water heater is not producing hot water?
(1) the gas is cut off; (2)the pilot light blew out and is not igniting the burner; (3)the thermostat is set too low for your requirements; (3)the thermocoupler is bad; (4)the pressure relief valve is stuck in the open position and discharging the hot water. 1,2,& 3 are self-explanatory. The thermocoupler is a bullet-shaped sensor located near the burner - it senses the temperature and turns the gas on or off to the burner according to the setting of the thermostat. The pressure relief valve is usually located at the top of the water heater on the hot water line and leads to the floor and under the house (separate from regular service hot water line) - it opens when the temperature of the water is too hot and discharges the hot water to keep the heater tank from over-heating and exploding. Hope this helps. Answer one is very good, but there is one error which requires correction. The thermocouple does NOT, as described in answer one, act as a demand thermostat for turning the main burner gas ON and OFF. The demand thermostat probe extends from the back of the gas control valve INTO the water INSIDE the heater tank. On the other hand, the thermocouple is located so as to be IN THE PILOT FLAME. Its purpose is to determine the presense of the pilot flame, and if the pilot flame goes out, the thermocouple will cool down, at which time, it TURNS OFF the gas TO THE PILOT. This is a safety feature designed to prevent the continued release of gas, which which if gaining contact with an open flame or any spark, would result in a devastating explosion.j3h.
When pilot light goes out on a boiler is gas escaping?
No. The pilot valve is closed when no flame is sensed by the thermocouple.
Does the safety valve on a gas range opens when the thermocouple detects no pilot flame?
yes
Can you light your pilot on your gas fire fireplace when your gas says off?
Maybe. Get the instuction manual for your fireplace. Depends on whether the OFF is master valve, or secondary valve. If no manual, hire a gas service company to do it, and show you how.
Does rotating a gas valve on an indoor fireplace counterclockwise open or close the gas line?
All gas fireplaces have to have a shut-off valve within 10' and that will turn so the key or the handle is parallel to leave gas on and perpendicular to turn gas off. The valve inside the fireplace turns but not indiscriminately. The inner valve will turn to the pilot setting and depress to light the pilot. Once the pilot os stable the knob will un-depress and turn to the On position. For a manual valve this will turn on the gas flow to the main burners. If using a switch or remote turning the valve to On leaves the fireplace valve in a Ready position so the switch or remote will turn on the gas.
How do you repair a gas fireplace?
Replace the thermocouple. The skinny copper line that goes from the gas valve to the pilot and senses when it is lit.
What causes a gas hot water pilot lite to go out?
No, that is part of the function of the pilot light. To light the burner and to keep the gas valve open. The thermocouple sits in the flame of the pilot and produces a small electrical current that keep the gas valve open. When the tank cools down, the thermostat opens the valve to the burner so that it can light. When the pilot goes out, it is usually the thermocouple that is bad.
What is flame rectification?
Flame rectification is DC electrical circuit that sends a very small voltage (rated in micro amps) from the furnace electronic board up through the pilot electrode. When pilot flame is established the flame acts as a path (conductor) which allows the DC current to flow from the flame rod to ground completing the circuit. This completed signal tells the electronic board it's ok to allow the main gas valve to open . Now your furnace pilot, or hot surface ignitor will start the main flame . To put it simple, flame rectification is an electronic way to prove pilot flame before opening the main burner gas valve. It's a safety circuit to prevent the main burner gas valve from opening if there isn't apilot flame, or hot surface ignitor established.
How do keep the pilot on in my gas heater?
Depress pilot valve, hold in while lighting, hold in for 2 minutes while lit. Continue to hold pilot valve in while rotating the gas control to the "on" position. If the pilot flame doesn't stay lit, it may be due to a bad thermocouple, a device that looks like a thick, solid copper wire whose tip is in the pilot flame and whose other end is screwed into the gas valve. You would need to get a replacement thermocouple from a hardware store or have a handyman install a replacement thermocouple for you. Thermocouples typically last 6-8 years if the pilot flame burns continuously.
Why does your Richmond water heater pilot turn off?
It is most likely the thermocouple that is bad. That is what keeps the pilot light on. The thermocouple is the small tube that sits in the flame of the pilot and runs to the control valve.
Pilot lite on teledyne laars mini therm 2 wont stay lit?
Replacing the thermocouple that the pilot flame touches when it is lit will fix the problem 90% of the time. A thermocouple costs about ten dollars and allows the gas to the pilot and main tube to flow by generating millivolts from the heat of the pilot flame. The thermocouple is a copper wire attached by a small nut to the main gas valve near the pilot tube coming out of the gas valve.
Why does your gas water heater flame go out as soon as it lights. My pilot stays lit. Is this a bad T-Stat or gas valve?
sounds like you have a bad thermocouple. The thermocouple senses the pilot flame and produces voltage to tell main flame to light. Thermocouple can be bought at any hardware store.
How do you relight the pilot-light of the home heating furnace?
Turn the knob on the top of the gas valve to "Pilot" and hold it down. Put your match or lighter near the pilot and it should light. Continue holding the knob down for about 30 seconds then release, and the pilot should stay lit. If it goes out then you may need to replace the thermocouple (the gold color rod that the pilot flame burns on) or have the pilot cleaned if it has a yellow flame.
