Are you using natural gas or propane (LP)? It sounds like you may need to change the orifice size on the gas lines going to each burner. If you are using LP and have the orifice set for Natural gas, the flames will burn higher and hotter, causing heavy soot. Under each burner, there should be a small nut with a hole in the center at the end of the gas line. The hole for Natural gas has a slightly larger diameter than one for LP. Your stove should have come with extra orifices as part of a conversion kit. Could this be the case? There's also another orifice in the main gas regulator in the back of the stove. Have you checked to see if the orifice for the regulator is set correctly? Does the oven burn hotter than usual with heavy soot, too? If you could please answer these questions first, I can give you better advice. Let me know...

Dirty flames

You have a problem with either air supply or with the burner getting dirty.  Clean out throughly with solvent type cleaners...no abrasives.  You should only have blue flames.

If I remember correctly, you will find three TX-15 torx head screws holding each burner head to the range top which must be removed, then you can use a putty knife to push in the clips which secure the top to the oven frame. These clips are located at the front of the stove top, at the seam of the top to the range, a couple inches in from the left and right side. Then lift top up at the front.
