You have to hold for 30 secs to minute once flame is lit if it is like more gas ignition systems

    ok if you are holding it for that long then your thermocouple has failed and you need to replace it. the thermocouple is at the pilot light and it is a small rod that burns in the pilot flame, it is connected to the gas valve. just remove it and install a new one not a difficult process.. the thermocouple is a safety that allow the pilot to hold and stay lit and therefore send a millivolt signal back to the valve letting it know it is ok to send a large amount of gas to the burner,

    I am not a wanna be tech! and he is not a customer, a customer pays you !! you are offering advise.And i read your solution again and I dont see thermocouple mentioned and besides it is a thermoplie issue anyway, the unit he has can have pilot lit and completely remove the thermopile if you want and pilot will stay lit, other units this is not so but for his it is. Don't get a mad because you are wrong its all a learning curve even with 30 years exp and I am sure the guy never thought you were any less helpfull he is only looking for solutions. I never mean't any disrespect to you at all and if anything your comments to me are very disrespectful and you should take your own advise.

Before you go changing parts, clean up the pilot assembly. When you heat metal and let it cool and heat it again it causes it to corrode. Also for some reason these areas seem to attract little spiders who make their homes here. This causes gas flow problems which in turn could affect the size and direction the pilot flame. For if it does not touch the thermocouple, thermopile or whatever that little thingy is called that tells the gas valve to allow the gas to will not tell the gas valvle to let it flow. Remove the corrosion, spiders, spider webs and any other insects then sand the thermocouple, thermopile or whatever that little thingy is with a rough sandpaper to remove corrosion. It will likely work after that.

I maintain six similar heaters for a restaurant in Charlotte, NC. Rust and bugs seems to be what gets them every time.

John Rodgers1, I have no respect for some wanna be tech telling a customer that I was wrong on a solution!!! You don't put other techs down!! Its wrong. If you go back and read my partial solution, you will find I said the thermopile Generator And or thermocouple is what keeps the pilot lite. You can check either with a meter to check the milivolts. So in the future, keep your smart *** comments to yourself. Have more respect for your fellow techs. If you feel they are wrong, say you don't agree.

    In Regards to your last comment, you were totally out of line. I have also replaced more generators and thermocouples then I have gas valves and am quite familar with both. The question if you will go back and read is how do I check a thermopile generator? If the pilot doesn't stay lit when you press and hold the knob down in the pilot posistion and dies when you let go, you have a bad generater or thermocouple. Thats common sense just as a water heater thermocouple. Just show some respect for your fellow techs even if you think they are wrong or right. My ratings speak for themselfs.

How do you light the pilot

Turn the gas knob to the pilot setting, press it in and hold it. You should hear gas escaping while in this position. Do not let more than about 10 seconds of gas out at one time as it may pool. Light the pilot while holding the gas knob down for a minute. Release the gas knob (the pilot flame should stay lit) and turn it to the ON position. To make sure the gas heater is working properly, turn up the thermostat and see if the heater heats up. How To Light The Pilot Light On Gas Heater

Is there a trick to starting the Pyrox 400? Turned the fan on and press on low then repeatedly press the ignition pilot light, start to smell of gas after a minute. Won't start Help please

Is the ignition sparking? When you press and hold down the buttons, the ignition should be sparking at the centre electrode. At the same time when you hold the buttons down, the gas valve is manually held open to release the gas. The spark is then supposed to ignite the gas. Hold the knobs down for about 3 to 5 seconds after ignition and the gas valve will stay on. If it lights but the flame wont stay on, it could be anything from a partially blocked aeration port to a worn knob. When you push down on the knob, it is supposed to press down on an electromagnetic lock which keeps the gas valve open when the flame is burning. When the knob or shaft isn't pushing down enough, it doesn't keep the gas valve locked and the flame will go out as soon as you let the knob go.

Pilot light blew out by a fan..I turned the control off..How do I Ignite Please

First locate where to light pilot. You can do this by following thin aluminum colored tubing from control valve to inside heater.In general on top of your gas control valve is a knob. Turn indicator of this knob to pilot and depress knob. This will start gas flow to pilot at end of thin tube. Hold this knob in the depressed position and light pilot. DO NOT release knob for 30 -45 seconds. Then release knob and pilot will remain lit. Then turn knob to on position. If pilot will not stay lit you may need a new thermo coupler, which senses heat from flame to keep pilot gas flow open.
Good luck

How do I keep my gas fire pit lit?

My guess is hold in the button for 30 seconds and the slowly release the button. The thermocouple has to first warm up before you release the knob. Remember wait and then release slowly. Just a guess.

Gas flows and heater ignites with the light button pushed. gas shuts off when button is released.

This sounds like a bad thermocouple, what this does is sense flame by heat. You can try to clean it with steel wool and make sure it is tight where it goes to the gas valve. Make sure it is on the top center pert of the flame as this is the hottest part of the flame. If cleaning does not work replacing it will.

The pilot will light manually with a match but after a minute when the knob is released the gas will stop to the pilot and the flame goes out when turnign to "ON"

sounds like you need to replace the thermocouple. this part is heated by the pilot flame and it sends a low voltage flame to the gas valve to open the main gas flow valve. they are very easy to install and they are located next to the pilot burner and screw into the gas valve.

How do I lite a wall room heater

First, turn off the gas valve for at least 5 min and ventilate the room. Most wall heaters are lit the same as a water heater. Find a red button to push or turn the gas valve knob to the pilot position. While pressing the red button or the gas valve knob, hold a match to light the pilot flame. After it lights continue holding the knob for one or two minutes. If the flame goes out when you release the knob the thermocouple is probably bad.

Igniting a Dometic gas fridge
    Electronic Ignition
    1. Open gas cylinder or pressure regulating valve
    2. Turn on Electronic ignitor switch
    3. Turn gas control knob to the MAX position, press and hold down
    4. After ignition, hold down knob for a further 15 seconds before releasing. The neon light will stop flashing
    Piezo Ignition
    1. Open gas cylinder or pressure regulating valve
    2. Turn gas control knob to the MAX position, press and hold down
    3. After approximately 10-15 seconds
      press Piezo knob several times until pilot light a lit
    4. After ignition, hold down knob for a further 15 seconds before releasing
  1. Check the Pilot light is alight
  2. The flame can be controlled by aperture ©
    Should no ignition occur, repeat the ignition process after 1 minute
    (This could take longer than 10 seconds if the unit has been out of operation for a prolonged period or after replacing the gas cylinder. (Cause: air in the lines)
  3. Once sufficient refrigeration has been obtained in the cooling tank at the MAX position, the control knob should be turned to the MIN position by low outside temperatures or when the refrigerator is only lightly loaded respectively the ambient temperature is below +18c in order to avoid over freezing the contents.
I hope this helps you...

Cozy wall heater

On top of the gas valve you will see a knob. Turn the knob to the position that says pilot. It's on the side of valve. Press the knob down with one hand and take your long lighter stick it by the pilot tube looks like a small aluminum tube should light pretty quickly hold for 30 seconds release the button you have been holding down. Now turn the knob to the on position. Make sure the thermostat is turned off so the flame don't fire up as soon as you turn knob. If you are uncomfortable gas your gas company and they should come out for free.
