Make sure the gas valve that is part of the supply line is on.
There is another gas valve inside the heater, which has three positions: OFF, ON, and PILOT. Turn the valve to PILOT, then press it down. This will allow gas to flow to the pilot light, so that at this point it should be able to be lit with a match or better yet, one of those butane fire starters.
Continue to hold the valve down, for about 30 seconds.
When you release it, the valve should come up, so that you will be able to turn it to the ON position.
If the pilot is still burning, you should be good to go.
If the pilot goes out, however, there is a chance that the pilot generator, a $50 or so brass cylinder that is positioned near the pilot light and which produces about 500 mv, is bad.
The pilot generator puts out enough power, using the heat of the pilot light, to energize a coil inside the gas valve to keep the gas flowing to the pilot. If there is no power generated by the pilot light, the gas valve will shut down (it's a safety feature so that the gas to the non-burning pilot does not continue to flow and create an explosion hazard).
You will need a digital voltmeter to check the pilot generator, and some other wrenches to replace it if it proves to be not producing at least 400 mv when hot.
Assuming the pilot stays lit, your next job will be to ensure the other limit switches in the circuit are OK, and that the thermostat is working OK to actuate the second coil inside the valve the turns on the gas to the burners. Your question, however, was only about the pilot light, so I will leave it at that.
I also have a Teledyne Laars natural gas pool heater and I found this answer when trying to figure out how to light mine. The previous answer was correct although it didn't tell you where the pilot light was (where you put the flame in order to light it).
On mine, you should follow a thin pipe from where the blue circular pilot/on/off switch is. It goes from left to right and then goes back.
On the right hand side, there should be a sign that says "pilot light here" with an arrow pointing back. The actual tube it points to is the pilot light.
You should use a long match or a butane fire starter to place a flame along the top of this tube.
Turn the blue switch until it can be pressed down. When you press it down you should hear gas flowing (a light hissing). If you don't, there is no gas getting to the appliance. Follow the pipe from the meter to the appliance and check for the gas turned off along the way (I have two shut-offs - one at the meter and one at the heater).
While pressing the blue switch down, hold a flame to the tube on the right. It should light the gas. Continue to hold the blue switch down for 30 seconds or so. I think it is heating something at the back. If you release the blue switch and the flame goes out, repeat the process.
Eventually, you'll see an orange flame at the back as things start to heat up. When you release the switch, it should stay lit.
Please note these instructions are from my perspective - your situation may differ. Use these instructions at your own risk. If in doubt, have your pool heater serviced by a furnace cleaner.

∙ 18y agoThe flame should generate a micro amount of voltage which keeps the burner going. If the burner won't stay lit the problem could be caused by a lazy pilot generator, dirty wire connections, high wind conditions, or even something more serious or clogged. Your best bet is to have a trained service technician from your local swimming pool company come out and give your heater the professional testing it deserves. You will find a properly tuned and installed heater will save you quite a bit these days with the high cost of fuel.

∙ 16y agoMost pool heaters are propane fueled. A match or lighter lit near the pilot light opening should suffice.
Hum, I would not say, "most" --- some would be a more adequate word.
The above previous answer would apply if you had an older style heater. All new heaters for the last several years have electronic ignition.

∙ 16y agoFirstly, how old is your heater? Do you in fact have a pilot light or is it an electronic ignition heater? If the latter, it has no pilot.
Older heaters have a gas valve knob that is rotated to "pilot" and then when ready with the ignition source, match, push the knob down and hold while holding the ignition source near the pilot flame outlet. Hold knob down for about 1 min. while pilot generator heats from that flame then let go and if the flame stays lit then rotate the knob to "heat" or "fire" or "run". In a brief amount of time the heater will fire. BE SURE TO KEEP FROM LOOKING INTO THE FIRE BOX TO WATCH THE HEATER FIRE!!!!!! STAND BACK FROM THE OPENING - YOU COULD GET BURNED OR AT LEAST LOOSE A LOT OF FACIAL HAIR AND/OR BE TERRIBLY FRIGHTENED BY THE RESULTING BLAST. Close and secure the heater door and listen for the combustion chamber to run continually.
If pilot does not stay lit then it is possible that the pilot generator needs to be replaced.

What if the pilot on your teledyne laars epg 250 pool heater will not stay lit and you have just replaced the pilot generator?
Check that you are getting voltage from the thermocouple. You should see about 600 millivolts.
When the pilot light cut off from the water heater for 2 days do you have to run water for it to reheat?
If the pilot light is on, the heater should come on by itself. If the pilot light is off then it has to be lit. If it will not stay on, the thermocouple is bad.
What do you do if the pilot of your wall heater wont stay lit?
The flame detector on the pilot assembly is probably defective. If you do not know how to fix this, call you gas supplier and have it repaired.
Water pool heater trouble shooting?
A number of problems can cause a swimming pool heater not to work. The most common I have found is lack of water flow. A heater needs a certain amount of water flowing through it to work correctly. The next most common problem is due to the pilot not lighting or remaining lit. This is usually due to the pilot generator not working. When you light a pilot light and have to hold it for a length of time before releasing the button you are allowing the pilot generator to heat up and then stay open to keep the pilot lit. Usually you need a licensed person to do work with changing items on a gas unit. The thermostat can be a problem for any water heater. Most of the heaters I have worked on were gas. If you have an electric heater waterflow still needs to be checked and the electrical connections can become corroded in the presence of chemically treated pool water.
Central heater will not come on?
My central heater will not come on while the pilot is lit,The heat does not kick on.
Why is your home heater blowing cold?
Check to see if you pilot light is lit
Why won't the burners stay lie on the pool heater?
If you mean "stay lit", you probably have a faulty thermocouple. This costs about $10 and a competent handyman or technician can fit it in less than an hour.

Your oven burners light but not your oven?
yes I can get the pilot to stay lit
What should you do if the pilot light won't stay lit on a Teledyne Laars pool heater and the pilot generator registers up 500 MV?
From what I have read, 500mV is not enough to keep the pilot light lit. Here is what I read on a different site: "You can check if this is the problem by measuring the voltage on the wires coming back from the pilot. When you have the red switch depressed, check the voltage (should be about 200mV). If there's no voltage, then change the thermocouple. The thermocouple will generate up to 750mV in a pilot flame. If it falls below 550mV it should kill the fuel source." Hope this helps.
How do you light the water heater pilot?
Turn knob to PILOT, press button down and light the pilot; hold button down for 60 seconds and release - pilot should remain lit; turn knob to ON. If pilot does not remain lit, turn knob to OFF, wait 5 minutes and try again, If pilot still will not remain lit, replace the thermocoupler.
How To Turn on and Ignite a Gas Wall Heater?
Sometimes figuring out how to turn on and ignite a gas wall heater can gradually turn into a very difficult and arduous process. In fact, learning how to turn on a wall heater does not require superior intelligence and it can be done quickly and safely without any of the hassle. Lighting the Pilot The pilot is simply a small flame inside of the heater that is constantly burning whether the heater is on or off. It’s there to ignite the gas when needed. Instead of immediately jumping into lighting the pilot, it’s a good idea to make sure the pilot is not already lit. If it’s not, then you are ready to light it. Search for a knob that reads “Pilot” and make sure it is turned to that setting. After turning it to the “Pilot” position, hold down the knob until you smell gas emitting. Release the knob and the pilot should stay lit. If the knob is not able to be pressed down, search for a red knob or something similar that can be pressed in. After holding the knob down for at least a minute, let go and the pilot should stay lit. If the pilot doesn’t stay lit, repeat the process of lighting the pilot again. If the pilot still refuses to light, there might be a problem with the heater. Powering On the Gas Now that your pilot is lit, you’ll want to turn the gas on so that your wall heater can begin actually producing heat. Locate the same knob that you turned to the “Pilot” position, and turn it to the “On” or “Operate” position. Doing this can be a little troublesome because it may take a few tries. Also remember that the flames might be a little intense if the knob is turned over to the “On” position too quickly. Setting the Desired Temperature Now that your gas has been turned on, you’re ready to set the temperature. Search for a knob with temperatures or numbers, and twist to the desired level.
