Umm...NO! That is not normal. Discontinue use immediatley.

It should be listed on the label unless it was changed at some point. The only way to tell is to use numbered drill bits to see what size hole is in each brass orfice of the burners, usually 3 to 5. The manual will list the orfice size for LP or NAT by the fryer BTU output. Most manuals can be found online, if you don't have a copy. This will require removing part of at least one burner to check the hole size. New orfices are normally about $20 each, most are marked on the side of the brass orfice. Note: some people drill out the holes to convert LP to NAT gas. Don't trust what is marked on the orfice, be sure to check with a drill bit. Small numbered bits can be hard to locate in most hardware stores. Found mine at Harbor Freight Tools.

This symptom indicates something wrong with the millivolt system. Start by checking the wires from the thermopile to the gas valve, insuring they are all tight and in place. Check the hi limit thermostat, if you have an ohm meter it should read .1 or .2 across it. With you meter set to dc millivolts, and flame present on the pilot, read across the thermocouple wires (red and white) to see the millivolts generated, with the thermostat off and the gas valve in pilot position you should get approx 600 millivolt plus minus 50. The pilot will have to be on for a minute or so to get maximum millivolts. If the millivolts are correct, hi-limit closed, and all wiring is connected, you likely have a faulty gas valve. If the hi limit reads more than .1 or .2 replace the limit, if you are not getting the millivolts from the thermopile, replace it.

The gas valve isn't cutting off fully. Call for service. Only gas certified engineers can work on gas appliances. ..

Usually needs the thermocouple replacing. As it is a gas fryer, it has to replace by a gas certified technician. Please don't type in all CAPS, it is considered SHOUTING and more difficult to read.

When the pilot goes out and won't stay lit is is usually because the Thermocouple safety device has failed. The burners should never be on when the thermostat is off. That is incredibly dangerous. You need a gas registered service technician.
