SOURCE: Cannon Rhapsody LPG Gas open Fire sooting up of burners
well its my experience that ranges don't come lpg they are all made natural gas but you convert them to lpg after purchase now if the lpg conversion isn't done properly then they soot like crazy proper lpg converson is to change the spuds on the burners and to turn the orifice over in the pressure regulator do you still have your owners manuel if so consult it on converting gas range to lp then check to see if every thing was done right on the pressure regulater there is a square cap you take it off and there is a round part that on one side says lp on the other says ng this changes the pressure that the regulator as ng and lp operates at different pressures and the regulator has to be set for what you using like i said im not familiar with your brand or model but i do know the problem if the range did come ng then you need to make sure the conversion most ranges aren't lp because there is not that big a market for it read the plate on the back will tell you if it was made ng or lp serial plate on front may say also most of the time it is beside the bottom drawer on the range

#1Your Air fuel mix ratio could be set incorrectly
usually for propane if it is adjustable it should be almost all the way open.
#2 you might have the incorrect orifice or it is plugged or damaged.
#3 your exhaust could be blocked
soot build up means that the fuel is not burning efficently and unspent fuel is escaping with the exhaust.

Had same problem. Coleman tech support said, " clean with pipe cleaners". No directions....I would think they would provide a step by step protocol. So, I chose to take the knobs off and use the pipe cleaner where I could. I was able to take one of the two burner control knobs apart. After sticking the clean in every nook I could find, I put back together, and the flame on that burner is back to normal,
Good Luck--Daryl in Burnsville, MN

Ben, the burner holes were a good start. If you removed the burners to clean them. If not, it left a lot of debris inside the burners. Also, the Venturi valves may be clogged (Spiders love them) which would affect the air to gas ratio, Which would mean the burners weren't/aren't burning cleanly. If you didn't remove the burners, that's what you need to do, before anything else.
Hope this helps you to further troubleshoot and solve the problem. Happy Grilling.
