I just purchased and installed a new Tappan, ES200 Control, Self-Cleaning Oven with Sealed Gas burners. Made the conversion to LP correctly. The the broiler works correctly. My issue is the oven burner works like a blow torch. Have made every adjustment I know of to reduce (regulate) the flame size and nothing is working. Any help?
Oh yes - just a little more background. Had purchased a GE with similar set up, installed it (again properly)and it had the exact same symptoms. Had a service person with an appliance company come out, said it was a bad regulator.
I cannot believe I have purchased two brand new appliances with bad regulators?
Previous oven worked fine until thermo-couple went bad, so I don't believe it is in the gas pressure.
Thanks

Hello Kansasmamaw and Welcome to the Do It Yourself Web Site and the Gas Appliances topic.
Some orifices are not adjustable. Which may or may not be the case here. If turning the orifice clockwise until it bottoms out does not stop the gas flow to the burner, the orifice is non adjustable.
No amount of adjustment will change the burners flame size in this case. The orifice would then need to be changed to an LP orifice of the same Btu rating as the existing orifice size.
Not very likely to have one adjustable orifice (in the broiler) and one non adjustable for the oven burner. Possible but not common or likely. In this instance it may be the cause of the oven burner flames to be excessively large.
Remove the ovens orifice and look for a pointed pin sticking up under the orifice. That pin will be pushed into the threaded tube the orifice screws on to. If none is there, that orifice is non adjustable. Orifice will have to be replaced with a propane orifice of the same Btu rating as the natural gas orifice.
Instructions for conversion should explain such. But may not. Instructions likely assumes, incorrectly, both orifices are adjustable,which may not be the case. Conversion kit with parts may have the correct orifice.You did not mention using a kit. Assumption had to be made on this.
Brand new appliance? May be covered under warranty.
Retail parts dealers and appliances parts stores can also help determine what the possible problem may be based upon that specific brand and model. Bring the make, model and serial numbers. Dealers and appliances parts stores are listed in the phone book.

I will check tonite when I get home. As I searched the archive here, I noticed this same issue on a couple of different threads. I will advise when completed.
Yes we did use a conversion kit and you are correct in assuming the instructions do not mention that the orifice in the oven "may not" be adjustable.
Thank you

Went home, reveiwed all instructions for conversion. It "seemed" we did everything correctly. Learned something new though. Don't always take manufacturers instructions at face value.
The orifice for the oven is the adjustable type. According to the instructions, you are to turn the adjustment tube 1 1/2 turns to snug it to the base, without over tightening.
Well - if anyone searches this and wants to know - go ahead and make it "very snug". Obviously you don't want so much pressure as to break the orifice, however, just running the adjustment nut down to "snug" will not be enough.
After tightening the adjustment nut to "very snug", the oven immediately began operating properly. The required 1" flame with no excessive yellow or lifting.
Patience is the key. And thanks to this site for the help.

Hello: kansasmamaw
Correct. Not all Mfg's instructions are exactly correct nor always accurate. The writers of those instructions do not often use the products nor test the products nor the results of the instructions they write about. Sad but some times it true. Having some hands on experiences helps....:) :thumbup:
Burner flames for an oven can be not more then 1 inch in wards from the ends (both sides) of the flame spread plate. In other words, burner flame size can be large enough to span out wards on the flame spreader plate, which sits on top of the burner tube, but must be at least one or one and half inches in wards from the outer ends of the plate.
No yellow any where in the flames must exist. If any yellow does exist and the flame size is correct, the air shutter must be slightly adjusted open more to remove all yellow in the flames. And the shutter cannot be opened so far as to cause the flames to blow or lift off of the burner and or away from it.
