I have a Genesis 1000 that I rebuilt last year or the year before with new everything inside including the regulator and it burns hotter closer to the knobs than on the other side. There is quite a bit of difference. I also usually only use the two outer burners but even if I use all three, it is the same story.
Does anyone know what could be causing this?
Wayne </div></BLOCKQUOTE>Hi Wayne,
Even distribution depends on the surface area of the burner holes being much less than the surface area of the burner tube itself. If that is not the case, then there will be a pressure drop along the burner tube and as you get toward the end, flow through the burner holes will be less due to less pressure pushing the gas through the holes. (I hope this makes sense.)
I can think of two areas that could affect this off hand.
1) The burner holes are too large. This seems unlikely if you have replaced the burner tubes, but could be possible if the tubes have been cleaned and something poked in the holes that would enlarge them.
2) Partial obstruction of the burner tube. If there is dust and debris coating the inside of the tube from years of use, it could partially obstruct flow and result in excess pressure drop. Similarly, if there are spider webs in the burner tubes due to missing spider guards, this could happen in new tubes in a relatively short time.
3) (OK, three things.
) If the wrong manifold and orifices is installed, it could result in excess flow that could result in an excess pressure drop through the tube at high settings. If this is the case, I would think that the flame distribution would be better when the burner is turned down. Turning down the burner would tend to mask the previous two issues as well.
4) (One more thing... ) If the burner tubes were poorly manufactured resulting in larger holes closer to the inlet end, there would be uneven distribution at all turn down settings. I would consider this the least likely possibility.
Perhaps someone else has solved this problem and can chime in with other suggestions.
HTH,

Hi Hank,
I forgot I even responded to this post and just found your reply. Everything inside is new including a new regulator since this problem was there from the beginning. I bought the regulator from Weber so I'm assuming it is the correct one but who knows. All of the spider gaurds are new and in place.
I don't put the burner on very high since this thing really heats up. I have just learned to live with the temperature differences on both sides.
