Once more and then I am through guys........... Respects to all.... I am just trying to help, not cause an argument.....cj......
I also would strongly suggest that the man read this article before attempting to clean the burner orifice .............
try this link this is where I got my information and this is what I did when my ''refer'' stopped working...

Orifice. The orifice is the very last component in the propane system before the burner, and has a very precise hole manufactured into it. The orifice and the pressure of the gas passing through it set the size of the burner flame. If one or the other is incorrect, then the flame will not be correct. Usually, if there is a problem, the orifice is dirty. Microscopic debris has accumulated around the hole making it smaller and therefore not the correct size. Also, oil from the propane tank and other propane components can be deposited on the orifice, making it easier for debris to stick to it.
To clean the orifice, first remove it. Sometimes blowing air through the orifice will clean it, but since you already have it out, you should soak it in alcohol or paint thinner (some non-oily solvent) for a few hours to dissolve any oil build up. And, then blow air through it. Do NOT poke anything into the orifice. It is such a precise hole, that you will either accomplish nothing or you will enlarge it and ruin it. There are no orifice bits for RV refrigerator orifices. In fact, there is no apparent logic in the numbering of orifices between manufacturers. A Dometic #58 orifice is roughly equivalent to a Norcold .16 orifice. Sometimes, even after repeated cleanings of the orifice, the flame is still not right and in your heart you feel everything else is right. This is possible. Sometimes an orifice seems to be uncleanable or can be defective. If you can, replace the orifice. If you can't replace the orifice -- keep cleaning. One important thing to note is that if you enlarge the orifice, you will increase the heat output of the flame and ruin the cooling unit Another, rarer problem on metal orifices is that the flow of propane over the years can actually erode the orifice and either make it out of round or enlarge it. In the either case, the orifice has to be replaced.
Nuff said on my part .......... cj........ GOOD LUCK
God bless the troops that fought in Desert Storm.......
