The easiest way is simply hold down the pilot lighting button until the gas pushes the air out. The longer the pipes with the air in them, the longer this takes. You are only looking at 4 PSI for natural gas, so a 20 ft line may take several minutes. You do not want a gas build up, so as you are holding down the button, hit the ignitor every 2 or 3 seconds or so. this could take 5 to 10 min solid of holding down the pilot button.

The other way is to loosen the gas line as close to the gas valve as possible to let the pressure push out the air until you smell gas.

That method can be annoying at times, and you will still need to purge the gas valve and manifold. Thus my previous suggestion. Once you statr to smell gas vapors it should light soon after.

It is not uncommon for the pilot to light, burn weakly and go out only to have to be relit a time or two due to pockets of air in the lines.

Light pilot light

Many heaters have pilot flames can be relighted with a match or push button operation. Many employ safeguards to prevent unburnt fuel from accumulating in the space or allowing an unstable pilot flame from "proving".

Most appliances have instructions printed or embossed on or near the pilot, gas valve or protective cover. It is very important to closely follow these instructions for your safety and that of others in the area. If you are unable to locate the instructions or follow them and relight the pilot, you should contact the gas company for assistance. This can be in indication of an issue with fuel, thermocouple, gas valve, etc., and would require a service person to correct.

I have included a link to a video to light a gas heater - yours may be the same or similar:

Oven does not light

1st is the gas on. 2. If the gas is on and you follow the instructions to light the pilot by holding the button in for the normal time and it wont stay lit 99% of the time the thermal couple needs to be replaced. Not sure what that is? There is a thin copper line that connects to the box where you push the pilot button and the other end has a small rod that connects to the pilot. It is possible to replace it yourself if you are handy or call a restaurant repair company to come out and replace it.

I would suggest that you remove pilot assembly from gas valve and burner and clean pilot orifice and see if that helps. Be careful when cleaning hole in the orifice so you don't enlarge the hole. Good luck and thank you.

If your GE hot water heater fails to light, the first thing you should do is make sure the gas is turned on. Before checking the gas be sure to turn the control knob over to "Pilot." This will prevent the heater from coming on unexpectedly while you are checking the unit. After making sure that the knob is set to "Pilot," carefully remove the cover and look for the flame at the end of the gas line.
If the pilot light is not on, it is possible that the gas inlet valve is partially or totally closed. To check, turn the handle next to the line and follow the instructions on the tank to relight the pilot light. Keep the cover off of the unit and look for the pilot light to go on. If the pilot light does not light, gas may not be flowing. If you suspect a problem with the gas line, be sure to contact your utility company right away.
If you suspect that the burner on your GE hot water heater is not on, remove the cover and carefully look at the burner. If the burner is not on, make sure that the thermostat is set properly. The thermostat should be set to approximately 120 degrees Fahrenheit - if the setting it not right adjust it and then turn on a hot water faucet and allow it to run for several minutes. After the faucet has been running for a few minutes, look at the burner again. If the burner does not ignite, try adjusting the thermostat up and down until the burner comes on.
Good luck.

No gas going to my water heater

A bad/dirty thermocouple or pilot safety sensor will prevent the main gas valve from opening up and allowing gas to the main burner and will prevent the pilot from STAYING lit.

A bad thermocouple indication is the pilot will light while you are holding down on the pilot start button (thermo-couple is over ridden) but as soon as you release the button the pilot goes out.

If your description of the problem is correct and you cannot even light the pilot even while holding down the pilot light button AND you have followed all the proper relight procedures I would suspect
a dirty pilot orifice or condensation build up in the gas trap.

If you can NEVER LIGHT THE PILOT follow the steps given below: if it lights and goes out when you release the button and you have a nice blue pilot flame the problem is the thermocouple or gas valve (most likely the thermocouple).

If the pilot is yellow and weak looking and the pilot shuts off when the button is released follow the following instructions also as a weak pilot indicates a blocked/dirty orifice and will not get hot enough to activate the thermo couple and presents as a thermocouple problem.

Turn off gas and remove the cap on the bottom of the trap (little stub of pipe that hangs down below the gas line usually on a tee). Drain any condensate out, reinstall cap being sure to seal threads with dope or teflon tape. Then remove pilot tube from the heater and scrub the small pilot tubes orifice. It is very small and plugs easily with debris, rust scale etc. You may need to probe it with a tiny wire to get it clear, if so do not damage or enlarge the hole by going gorilla with it. Once you are sure orifice is clear and clean re-install, turn gas back on and attempt relight sequence, you may need to do it several times to purge air out of system. While you are at it you should also give the thermocouple a good scrubbing, steel wool or scotch brite nylon pads will do just fine for this, you just want to clear it of carbon or any corrosion.

You should get a nice blue flame on the pilot>

If you still cannot get the pilot to light AT ALL you most likely have a gas valve problem and need professional help to diagnose and fix.
