Kitchen Gas Appliances - kenmore 790 oven conversion problem

I have converted a new kenmore 790 gas oven to LP using the supplied kit. stove and broiler work great. I have a problem with the oven. The oven flame is not the recomended 1", but 5-6" and shooting out into the oven itself.
Any thoughts on what might be the problem. Sears has not been very helpful over the phone.
thanks in advance.

How did you convert? Normally an appliance regulator stem must be changed over, Top burner orifices closed down or replaced and oven burner orifice closed down or replaced. Sounds like the oven orifice has not been adjusted or not adjusted properly. DO NOT use oven until this has been corrected. Youay want to cal your LP supplier and have them check this out.

thanks for the reply.
it goes without saying that I am not using the oven...
in this conversion you close down the orifice. the instructions warn against over-tightening. could this be the problem? or would this shut the gas off?

overtightening even 1/4 turn can crack the very soft brass orifice. at this stage it cant hurt to remove orifice and inspect for damage! hate these new "adjustable" orifices. back in the day you either had a natural or an LP {it meant removing the orifice no matter what} but you knew it was right when done! p.s. if you are going to remove the orifice we must do so assuming that it may be damaged and be careful to make sure it comes out intact! i might suggest wrapping a small amount of teflon tape around orifice {soft enough to mold around orifice and ensure tight fit in socket!} learned of this after ruining threads and having to replace entire valve! hope this helps and good luck

As long as you can keep closing the orifice I would. The flame will tell you when you are there.

when i read the post i thought we had already figured out that we overtightened! my bad

Maybe I should of thought of that. There is no doubt damage may occur. Guess after you have worked on hundreds of ranges you tend to look at it differently. You know what to expect and where. I didn't mean to over simplifiy the job.

its cranked down darn tight...
so we all agree that the problem is the orifice?
have you ever seen this happen?

It sure sounds like it and yes. When you remove the orifice you will see a needle that was suppose to reduce the orifice opening. Apparently it did not allow the orifice to go down far enough. Time to call sears for orifice replacement me thinks or once again your local LP co

From what was said, it almost sounds like the only way to do this in a failsafe manner is take it out to tighten it -- or do it with the flame on - which doesn't sound safe to me.

Has anyone gotten any resolution on this problem? It doesn't seem like it's possible to tighten the snub oriface down too tonight - it looks like it runs out of threads before it can get tight enough.
