Why is my stove causing a thick coat of soot to buildup on my pots?

Adjust the air mixture on the oven burner. This is a metal part where the brass orifice is mounted on the burner valve. You loosten the screw on the side of it enough to be able to slide it back and forth. Get a flame going and move the barrel until the tips of the flame in the burner is completely blue...no part of the flame should be orange. Once that is done tighten the screw . automotive brake fluid is an excellent soot cleaner. It smells bad so use it with a lot of ventilation.

If you are getting soot residue, it could be a number of things, First, is this a natural gas or propane oven? If you bought an oven to be used for propane, it may need to be converted from natural gas to propane or it will soot everything up. 2nd, have you recently spilled food/liquid onto the oven burner? If the burner holes are partially plugged, the remaining holes will burn large yellow flames and soot up the oven. Check the burner flames, they should be mostly blue with little to no yellow tips. Also make sure the oven burner flames are not too big. They should never exceed the width of the flame spreader pan directly above the burner, in fact they should be less than half the width. You could also have other issues like improper air shutter adjustment to the oven burner or very low regulator pressure, but most likely it has just been spilled on recently.

If it is still producing soot two problems blocked burners burning yellow causes soot , or blocked injectors, or pressure to burners is wrong needs seting to correct pressure

It shouldn't be burning yellow and emitting soot at all;sounds like on of these possible causes-
(a)blocked burner airways(this can lead to yellow tipping and sooting on LPG powered appliances because insufficient air is getting through to the burner causing it;you can also get this effect on LPG barbecues say if dead insects or spiderwebs are in the burner pipes and airways after a period of storage),
(b)incorrect aeration being set when the burner was converted using LPG jets(too much gas and not enough air causing yellow flames/smells and sooting),
or (c) if you use propane cylinder gas a dicky or faulty regulator. I would get it looked at investigating all the possibilities I mention and taking action to correct this where necessary ie clearing the burner airways(if this is causing your problem), adjusting the aeration in the burners until you get a clear noiseless blue flame without any excessive yellow and sooting(but even after good adjustment you may find still get a very slight yellow tip without sooting at the top of the flame;this does happen with propane gas and there is a slight tendancy for this to happen more often with butane-butane tends to display very slight yellow tips on ignition increasing slightly as the burner warms up to full temperature) or if you use propane cylinder gas replacing the regulator if that is necessary.

clean the orfices and tubes and then if possible adjust your air mixture setting also

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,

the fuel to air mixture is set incorrectlty or your pressure at the ouitlet for the gas valve is too low.
you culd play around adjusting the first part of this but for the gas valve part you have to have a manaometer to check it out correctly. then it should be set at 10"wc. Good Luck

burners burning yellow , in complete combustion , blocked air ways to burner , it needs a service soon as poss

propane burns very dirty.you need to remove the burners and orfices and clean them good with oven cleaner.make sure their rinsed and dried well before installing,this should solve your problem.

three problems with slow ignite on stoves.. first one is clean ignitors and burner caps. make sure that the caps and burners are correctly assemble. and make sure the stove is grounded correctly.. Do you flames have orange to yellow tips then there is a unburn carbon thst will form soot. soot productions is not achieving complete or efficient burning...again you may have dirty ot clogged burners..the flames should be all blue...let me know what you find out
