Deep fryer shooting out flames from exhaust

SOURCE: Imperial deep fryer model: IFS-40

Sounds like the pilot is dirty,if you have propane gas this is your issue,replace the pilot either way.

Hello. Could be three things, from what you describe, it sounds like your pilot is dirty, and not heating the thermopile enougher, and pilot off to energize the pilot portion of the valve. You could also have a bad thermopile, and no matter how long you hold it, or if your pilot is good, will it energize the valve. The last thing is that your hi limit has failed, and is preventing your gas valve from getting any voltage at all on purpose, as it is a temperature actuated switch that will shut the fryer off it it gets too hot, it could have failed and is now keeping the pilot from coming on, some of these have a reset button you can push ( usually red ) that will reset it, but then why did it trip? either your thermostat is out of calibration, the bulb may be broken in the tank somewhere, or it may just be tripping too early, like 375, instead of 425 to 460 depending on spec.
Hope this helped, and thank you.

Make sure the regulator assembly on the gas valve is for propane. Sounds like the gas pressure is too low and the flames aren't going into the burner tubes. Make sure they didn't install an appliance regulator on the back of the fryer. This is not needed as the fryer has a regulator on the gas valve. You can unscrew the cap on the regulator assembly and turn the plastic screw inside all the way in. DO not turn with alot of force. Easy does it.
