Top 10 Imperial IFS40 Deep Fryer Questions & Answers

IT IS A GAS PRESSURE PROBLEM CHECK TO SEE IF THERE IS A GAS REGULATOR IN LINE WITH THE GAS PIPE TO THE FRYER IF SO ADJUST REGULATOR TAKE TOP ALUMINUM SCREW OF YOU WILL SEE WHITE PLASTIC SCREW TURN WHITE SCREWW TO THE RIGHT ALL THE WAY IF SAME PROBLEM OR NO REGULATOR RESTICTION IN GAS LINE

Try to clean the pilot orfice,ive seen even though the pilot stays lit it doesnt have enough millivolts to energize the gas valve.Did you check the wiring really good?

Hello. It sounds like your wiring is shorting or crossed for sure, or your gas valve has failed, but the pilot lights, and stays on, so good sign. If you hosed the hi-limit or the thermostat, these could short internally, and cause the pilot to drop out. Try this, disconnect the wiring going to the hi-limit ( control with the 3 screws ), and the thermostat, relight the pilot with only the thermopile connected to the gas valve, turn it to on, and see, if it stays, then a wiring problem, or component problem for sure. I see I cannot get a diagram from them, maybe you can call, and have them send you one. Let me know.

Hope that helped, and thank you.
If you need more help, "ask me",

remove connections from hi-limit switch, and put an ohm-meter across connections then heat it with a match or heat source of that temp range,heat the face and watch your meter it will show open when hi limit reaches cutoff limit/if you need exact cutout temp,you will need to have one of those digital read-out temp gun

Flame is Orange? If so, propane is "choked", not enough air. Remove burners, clean each burner hole with a same size metal dowel (coat hanger works well) flush out inside of burner with garden hose, hi pressure air through all holes to dry. Replace burners ONLY after also cleaning chambers and chimney (garden hose and long brush). Do not forget to clean pilot light area too.
Most Imperials are pre-set air intake. Check gas pressure if able, 3" NG, 10" LPG. Good Luck

Sounds like you may have the thermostat turned way too high.... If you don't, check to make sure it's working correctly, like is the temperature reading correct? Is your flue all junked up with build up and crud? If so, you will need to clean it out.... You can scrap it out with a dough scraper or anything else that works for you...Also, you might check your gas connections, or have your gas co check them, and see if there are any issues with the gas connection and the amount of gas coming into your fryer. Hope this helps you.

Hi there.
You will be needing a dc voltmeter set at millivolt to test a thermopile.
measure the voltage across the termials of the thermopile when it is heated by the pilot flame, you should have 600 to 750 millivolt reading.
If the reading is less than 600, try cleaning it with non metal scrubbing pad and/ or try increaing the pilot flame or you have to replace it with a new one.
Try the same with your other fryers with thermopile.
You will be able to find parts at http://www.imperialrange.com

In my experience, the thermocouple (you called it a thermopile) is usually the weak link that fails, and is also the least expensive to replace, so start there with a high degree of confidence.
The purpose of a thermocouple is to convert the heat of the pilot flame into millivolts of electricity, which holds the pilot gas valve open, assuring that there is a flame present if there is gas flowing. They typically cost around $20.
Here is the website for the manufacturer, which includes the manual download and contact information:

Number 5 is your thermopile/pilot generator. It is a pilot generator that does 2 things. It holds open the valve with a safety magnet and it operates the safety valve solenoid whenever the control stat calls for heat. Overtime they get weak and will hold the pilot but not operate the valve solenoid. I would replace that pilot generator.thermopile and party on!

Soot is caused by a few things in gas appliances. Propane even more so. Lack of combustion air is usually the culprit. In propane fired equipment orifice alignment, high pressure or the wrong burner orifice can cause yellow flames the result in soot build up. You need to find the culprit. Best to have a service tech check it out and clean it. when you know what to look for it can be easily fixed.
