LP fireplace rear burner search

[LindellProStaf]

I hope I am posting this in the right place. We bought a house and the previous owner put a natural gas fireplace in where it should have been a LP one. I changed the control valve and now need the orifices and a rear burner. I can get the orfices but cannot find a rear burner. Have looked on the net all over. It is a DESA fireplace and they went out of business a few years ago. The part # 104572-02 DESA rear burner. I would greatly appreciate any help. It is only about a $14.00 part but if I can't find one I have to buy a new fireplace. This model you cannot replace the insides like on some models. Of course... Thanks much.

Check with some companies that sell that type of outfit and maybe they can direct you, or better yet have the piece on hand.

You should not need the burner. All you need is the gas valve ,the burner orfice and the orfice for the pilot. I never seen an LP kit come with the burner. Find a heating shop and they should be able to find out what size burner orfice you need and get it set up for you.

What brand gas valve is in it? That's where I would start looking for parts. Burners good like mentioned above

Hi you guys and thanks for the input. I thought the same thing. The places that do have the orifices said I was wasting my money if I don't get the burner replaced too. They said that the holes are too big and that the orifices don't do the whole job, the burner restricts gas flow too. The burner is just a 1" pipe with a 90 degree bend in it. I was even thinking about plugging the existing holes and drilling out smaller ones.

The orfice is all that needs to be replaced. It is what allows the amount of gas to go through. I have installed alot of fireplaces and never replaced a burner tube when I put in a a LP kit. It is like on a stove or a furnace, you replace the orfices and the spring in the gas valve and it is converted. Just be sure to check gas pressure and the air adjusted right or it could soot up.

Hey thanks a lot Smoker. I am going to get the orifices and try it. It sure makes sense to me.

I've been in the Biz for 25 years and there are some units that do require a burner change out. FMI was a brand under the Desa corporation. FMI is still around. Google and call their tech. department. They should be able to help.
