I had the same problem when it would not light by itself I could press the sparker and it would light. I stold the limit switch from another one i was not using and put it in and it has not done it since. I think it was just getting weak.

Do you have an electrical meter that measures millivolts?This sounds like a millivolt system. The pilot orfice and pilot burner need to be clean so they are producing a hot flame, hitting the pilot generator to create enough millivoltage to open the main valve coil. If you know how to jumper the thermostat circuit try it, Millivolt systems will give you problems if there are loose connections or to much resistance through a switch. Again, there could be some type of safety switch that is wired into the thermostat circuit to prevent the heater from coming on if it isn't safe. Call a pro if its not obvious
Sounds like a millivolt system. If it is, there is only two wires that go to the thermostat. There should be two wires to connect the thermostat wires either down by the valve or on top of the furnace. Make sure the valve is turned to "on" and not just "pilot"
It could be several things: Is the Control Knob turned from Pilot to ON? If that is the case, wait a few minutes after turning it to ON. That will allow the Thermopile to heat up sufficiently. Be sure the flame is touching the Thermopile. If everything looks correct turn up your Thermostat to higher than the ambient room temperature and see if the burners light. Remember to turn your Wall Thermostat down to the lowest temperature setting before turning the knob from Pilot to ON.
FYI - That Wall Furnace does not have a Thermocouple. It uses a Thermopile instead to generate millivolts of electricity to open the gas valve and maintain the pilot flame.
If it is the Thermopile, you can order it directly from Empire Comfort Systems, as well as download your Owners Manual at www.empirecomfort.com
You need to replace the thermostat if you have to force the contacts to close.
Make sure you get the right type of stat. It appears this is a thermopile millivolt type, as opposed to a standard thermocouple. The stats are not interchangeable. I noted stats were available at Sears, but there I am sure there are other sources to purchase from.
It sounds like the gas valve is dropping out. Make sure the system is venting the exhaust(no restrictions). Then make sure all your wiring connections in the unit are tight. In a millivolt system if all wiring connections aren't tight and clean your circuit will drop in millivolts and the gas valve will drop out. The gas valve requires a certain millivolt to stay open. I hope I was of some assistance!! Good luck!!
Your unit has a "vent safety limit switch" which is a high temperature limit. It gets hot enough to trip over time because you do not have proper venting. It is a safety switch and SHOULD NOT be disabled - instead find and fix the venting problem(chimney bad?)!
This problem could be caused by a few different things. You should check the condition of your pilot and the thermocouple, if the pilot is weak due to being dirty you will not generate the optimum Millivolts to run the fryer, you may need to dissassemble and clean the pilot. The thermocouple needs to be correctly placed in the pilot assembly, if it has dropped down to where it is not in the flame it will not work correctly. You may need a new thermopile as it may not be generating millivolts as needed. Gas pressure can cause this as well, if the pilot goes out then the main burners come on you should check the gas pressure. One more thing to check is the hi-limit thermostat, if this is cutting out early your pilot will go out. Imperial uses a self-resetting limit, after a few minutes your fryer will relight and work until if cuts out again. If your fryer pilot stay on with the thermostat off for long periods of time and does not go out immediately when the burners come on and the pilot is clean, you may need a hi limit. This is a lot of info, I hope it helps.
check all limit switches to see if they can be reset if so reset it ,if problem reoccurs wich limit is going out ? make sure all wires are connected well to your gas valve , use a low voltage tester to make sure your firing circuit is operating properly , if you have a thermocouple it may not have enough juice left to open your gas valve
Pilot won't light - natural gas or propane. check for a spider web in the burner tube. check no dust in burner tube. check surface igniter is lit. if pilot lights check flame detector - may be a millivolt generator - it is a small capillary with a copper tip in flame path. no fire will keep the pilot valve closed. replace the generator.
