RED HOT FLUE EXHAUST

Hello. Yes this is normal for this type of fryer, meant more to cook the product, as efficiently as possible, and guzzle gas pretty good. If the orange is near the bottom of the flue, that is pretty good, there is , or should be insulation on the outside of the flue, or if the air gap is large enough, no insulation at all. Not getting near the exhaust pipe is advisable, or you will be burned. The gas pressure is important thought, if the burners are over/under pressured, it will affect the burn enough to damage, and shorten the life of the fry vessel. Call a local authorized servicer and have a check up, will not be free, but will save expense of something not being correct, most places, you pay an hour to check it good enough.

Hope that helped, and thank you.
