I can't keep the pilot lit. I replaced the thermal couple and confirmed when I hold down the pilot valve it will generate up to 700 to 800 mv. As soon as I release the pilot valve the gas cuts out. Not sure what the problem is. When I first started it up it ran for about 10 minutes the quit and I have not been able to get it running since. Thanks

turn gas supply on....turn gas valve to pilot....press down and hold to allow gas to come through pilot tubing.....light the pilot right by the thermal couple, once lit hold valve down for about 60-90 secs...then release ur hand on the gas valve and turn the valve to on position............make sure the bloody tstat is turned off before doin anything other wise burners will fire up soon as you turn valve to on position
Trying to light your pilot light and it keeps going out when you turn on you gas valve. This is a common problem when your thermo-couple goes out. The thermo-couple sends a small electrical charge to the gas valve to keep its self lit. When the unit calls for heat the pilot flame gets bigger producing more electric and tells the gas valve to open the main gas valve to the burner tubes. The thermo-couple is an easy item to change most of the time. You will need to follow these steps to change out your thermo-couple:
1. Turn off the gas (there is an inline shut off on the supply line before it reaches the gas valve, you need to turn this crossways to the pipe)
2. Locate the thermo-couple it will look like this and be attached to the gas valve
3. Unscrew the thermo-couple from the gas valve
4. Remove the other end of the thermo-couple from the pilot holder
5. Measure or take the old thermo-couple to the hardware or appliance store with you to get the proper length (there are many different lengths of thermo-couples)
6. Reinstall the bulb end at the pilot
7. Reinstall the threaded end on the Gas Valve (make sure not to cross thread the thermo-couple it should start by hand)
8. Turn the gas valve to the pilot position and hold down the red button wait a few seconds then turn off and do again (you will need to do this around 5 times in order to get the gas back up to the pilot light then try and light the pilot)
9. Try to ignite the pilot light.
10. Once you get the pilot light lit you will want to hold down the button for 60 seconds then turn the gas valve to the on position.
Here is an image of a thermo-couple (they will all look similar to this):

From looking at this parts list, I see that the gas valve is powered by a thermal generator. The generator holds open the gas valve AND operates the gas valve solenoid. Their are 2 thermostats one of which determines the desired cooking emt and another which is a limit that kills the operation if the oil exceeds 450 f. To light this puppy you move the gas valve selection knob to the PILOT position. Press in on the knob and light the pilot with a match. Keep holding down the knob till the flame stays on without the knob being pressed. Advance the knob to the ON position once you have the pilot lit. Most common problems for this rig: Bad thermal generator/thermopile. Weak thermal generator holds the safety pilot on till heat is called for then shuts down when the solenoid is energized. Bad solenoid operator on gas valve (non replaceable you must buy a new valve) Bad thermostat or limit. Pretty easy fix if you like getting greasy. LOL
pilot light keeps going out! more then likely its the thermal coupling doing this. if bad it shut all gas to heater for a safety measure. just shut power off, then turn gas off and replace it. then you should be ready to go. to relight heater hold down on gas vavle knob in the pilot position, hold down and light it at the coupling where gas comes out. when it is lit, continue to hold down for 60 seconds. release knob very slow. then if its lit, turn to the run position. if flme goes out, wait at least 5 minutes to expel the gas fumes and turn to pilot and try again. good-day !
Check the following:Pilot orifice or line partially clogged --- remove and clean. use a fine wire or drill bit to do this.Gas control valve going bad --- replace gas valve. Gas valves cannot be repaired.
I would check to make sure control on gas valve is in on position and pilot is lit if you have a standing pilot. If you have a spark or hot surface ignitor make sure they are trying to lit pilot. If you have standing pilot model and pilot lit is not on. Turn control on gas valve to off,wait five mins. then turn to pilot. Depress botton and try to light pilot. If it lights hold down for a couple of mins. then release.. If pilot stays lit turn control to on. If thermostat is calling for heat this should bring main burner on. If pilot does not stay lit then replace thermocouple. Hope this helps. Thanks
If it is a true "pilot" light, it needs to be held down long enough to generate the milivolts needed to prove to the gas valve that he is ready to open, other wise the gas valve would open, not igniting, thus causing a "gas leak". Turn the t-stat OFF, turn gas valve to pilot, push down on pilot knob, light pilot and hold for 2 minutes. After 2 mins let go, and if pilot stays lit, turn gas valve to ON, and turn the stat to heat and turn it up to desired temp. If pilot does not stay lit after doing above, try sanding thermo couple( the thing the flame is sitting in) or just spend the $15 bucks and replace therm couple. firstname.lastname@example.org
turn the dial to pilot and push and hold down red button while you light the pilot located inside water heater beside burner, keep holding button down after pilot is lit for about 1 minute. If you let go and pilot goes out repeat above steps and make sure pilot flame is heating up the thermal couple. If that fails replace themal couple.
The pilot must encompass the thermocouple "bulb" in order for the thermocouple to generate enough current to keep the pilot valve on. You must also hold the red button down for a long enough period to get the thermocouple hot. If the pilot is not large enough, it could be due to a clog in the pilot orifice at the pilot itself. Sometimes a couple of passes over the end of it with fine steel wool is all it takes to clear it.
Hope this helps. Feel free to share what you found. Thanks.
The thermal couple that senses the heat from the pilot and holds the gas valve in the ready condition must be bad. It is not difficult to replace. Note: When you first lite the pilot flame you must hold the button down for at least 30 seconds before releasing it. Also check the size of the pilot flame that contacts the thermocouple.
