Check the vent hole (plastic plug, not the screw) on the regulator between your gas line & the back of the fryer. If it is plugged, it wont fire & the pilot will go out when t-stat makes.

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

I am not a service professional, but just a homeowner who has some experience with this gas log.
GAS LOG INSTRUCTIONS
Brand: Marco Gas Log (company is now out of business)
#792775, unvented gas log
Installed late 1990's when house was built
The gas is turned on and off using the key on the wall to the left of the fireplace. The gas is OFF when the key is turned as far clockwise as possible. Turn the key counterclockwise about a half turn or whole turn (180 degrees to 360 degrees) to light the pilot and turn on the log. You don't have to worry about gas coming out into the room before you light the pilot, or if the pilot goes out.
Horizontal as far clockwise as possible = OFF
Vertical ½ turn = ON
The log needs to be cleaned before using at the beginning of the season. Remove the logs, taking note of their position so you can replace them the same way. Use a toothbrush to clean the thermocouple, which looks like two little wires immediately to the right of the pilot (which looks like a metal tube that is located in the center just in front of the back log). Use a vacuum cleaner hose and duster to clean dust off all metal parts and the fire box interior. You can go ahead and replace the back log before lighting the pilot.
HOW TO LIGHT THE PILOT:
With the gas turned on with the key on the wall, find the black and white knob on the lower right of the gas log and turn it all the way to the right (clockwise) to the to the right as far as it will go, then turn it back ever so slightly to the left until you feel a little resistance (like a click that you feel rather than hear). The pilot cannot be lit when turned all the way to the right.
Push the knob in with your thumb and use your other hand to light the pilot with a long-stem lighter or match. Hold the knob in for at least 30 seconds. The thermocouple has to be hot before the pilot will stay on. Let the knob come out very slowly. Hopefully the pilot will remain lit, but if it does not, you will need to repeat the procedure until it does. Be sure to hold the knob in until the thermocouple is hot and release the knob very carefully. When the pilot stays lit, then turn the knob to the left counterclockwise until the flame stays lit and carefully place the logs back into their original position. Note: Push the knob in only when you are actually lighting the pilot, not while you are turning the knob.
Set the thermostat from Hi to Low as pictured on the knob. Once the log is lit, it should stay on until the thermostat causes it to go off. Hopefully the pilot will stay on so that the log will come back on automatically according to the setting of the thermostat (from low to high). It will be at its hottest when the knob is all the way counterclockwise.The flame will go off and on according to the temperature in the room. The pilot should stay lit even when the main flame goes out, as shown above.
From the Owners' manual:
LIGHTING
1. Before attempting to light this appliance, the door if so equipped, shall be open.
2. Turn the appliance manual gas shut-off valve to the OFF position.
3. Turn the combination gas control knob to the OFF position.
4. Turn the thermostat control to the OFF position.
5. Wait 5 minutes.
6. Turn the appliance manual gas shut-off valve to the ON position.
7. Turn the combination gas control knob to the PILOT position.
8. Light the pilot with a match while depressing and holding the combination gas control knob until the pilot remains
lit upon releasing the gas control knob.
9. Turn the combination gas control knob to the ON position.
10. Turn the thermostat control knob to the desired temperature to turn burners ON.
11. Ensure that the door is closed during operation.
12. For complete shut-down, repeat steps 2, 3, and 4.
It won't turn any further until the pilot is lit and stays lit.
You need to turn the knob on the gas valve (inside the heater) to the "pilot" position. Then, while holding a flame over the pilot assembly push down on the knob.
Gas should come out of the pilot and ignite. Continue holding the knob down for 10-15 seconds. Release the knob and the pilot should stay lit. If not the pilot generator may need to be replaced.
Turn the knob to the "on" position, close the heater and turn the heater on and turn the thermostat to hot. The heater should fire. If it does not fire and the pilot goes out, that may also indicate a pilot generator problem.
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
TO LIGHT THE PILOT
1.Open the door.
2. Turn the thermostat OFF The thermostat is located
behind the door.
3. Push the gas control valve knob and turn to OFF. Wait 5 minutes for unburned gas
to vent.
4. Push and turn gas control valve knob to the "L" in PILOT.
5. While still holding the knob in, light the pilot with a lit flame. Continue to depress the
knob until pilot remains lit when knob is released. If the pilot does not remain lit,
repeat step 3 through 5.
6. Depress and turn gas control knob to ON
Is there a "Pilot" marking on the knob? Try moving the knob 1/2 way between on and off and depress the knob. If you are in the correct location, the knob should depress in about 3/8 of an inch. Once you find the location where you can depress the knob, there should be a red sparker button that you can snap to light the pilot. Depress the pilot knob and snap the button a few times. There may be a small viewing port at the pilot. It may be covered by a small metal shield held on by a thumb screw. You can remove the shield to view the flame. OK so now you can depress the pilot knob, snap the sparker, look for the flame while still holding down the pilot knob and count to 30. Slowly release the pilot knob and check to see if the pilot is still on. Once it stays lit, rotate the knob to the "ON" position.
make sure that the thermocouple is staying in the flame youmay want to replace it unless it is staing lit on its own until knob is turned if so gas valve bad
The steps involved can vary slightly depending on your furnace model and pilot valve type, so if possible try and find the instructions inside the furnace door cover or in the instruction manual.
This is for a gas fired furnace, but applies to any gas-fueled appliance including water heater.
Two of the most common types of pilot valve body assemblies either have a red reset button and a gas valve or no reset button and a valve knob that can be depressed. But whichever type you've got, if you have an older model furnace with a standing pilot (flame is lit all the time) then this is the basic procedure.
Turn you thermostat to 80 degrees or to a setting that will demand heat. Make sure the thermostat is in "Heat" mode.
Go to the furnace and find the pilot valve. The pilot valve body is a box shaped device into which the main gas line will run and is located near the gas burners. It will usually have a gas **** or valve knob that reads "On, "Pilot" and "Off." Locate this gas **** or knob.
Turn the knob or gas **** to the "Off" position and wait about 3 minutes for any residual gas to clear away.
Find the pilot. It's located near the gas burner tube assembly in the furnace.
Get your match or lighter ready. Sometimes the pilot is hard to reach. If possible, try and use a long fireplace match when you light it. If you don't have a fireplace match then a butane BBQ grill lighter works well too. If you don't have that, then you can fasten a match to the end of a stick when you light the pilot
If you have a pilot with a red Reset button, turn the gas valve from "Off," to "Pilot."
If you have a pilot with no red button, turn the knob from "Off" to "Pilot."
Place the lit match or ignited lighter tip at the pilot and depress and hold the button or depress the knob as appropriate. Depress the button or knob for about 30 seconds. This maintains gas flow to the pilot until the thermocouple gets hot enough to open the main gas valve.
Once the pilot stays lit, slowly release the button or knob and turn the gas **** or knob from the "Pilot" position to the "On" position. This will ignite the burners and keep the flow of gas supplied as required for the burners as called for by the thermostat.
If the burners fail to ignite then it may be because the thermocouple did not get hot enough to open the gas valve. Wait a few minutes and then repeat the above procedure. This time hold the red reset button or depress the knob for about 45-60 seconds.
Once the main furnace burners ignite, adjust the thermostat to the desired setting.
If you've followed the previous steps on lighting the pilot and it still does not light after, or will not stay lit, then you probably have a problem with the thermocouple or an adjustment needs to be made to the pilot. You'll need a furnace service technician to replace or repair these parts.
You may find that the pilot lights, but it is an anemic looking flame. That's a different problem we'll look at in the next section.
If the pilot lights but the flame is a weak yellow flame, it will not get hot enough to heat the thermocouple to its set point allowing the gas valve to open.
A natural gas flame should be a bright blue with the tip of the flame having just a tinge of yellow. A propane flame should have a bluish green flame with a tinge of yellow at the tip. The flame should be strong enough to hit the thermocouple tip about 1/2 inch from the tip end. If the flame is weak or shaky looking, check to see that a breeze or draft is not blowing on it.
Adjusting the Flame There is usually a small screw on the pilot valve body that will adjust the flame. You may have to refer to the manufacturer's instructions to find the screw. Turn the screw as needed to adjust the flame throw.
Yellow Flame A yellow flame is caused by lack of air and incomplete combustion. It can be caused by a dirty pilot tube tip.
Split Flame This is caused by dirt in the pilot tube. Take a needle or small nail and gently clean the tube.
Flickering or Wavering Flame A flame that flickers is usually caused by a draft.
