Re: one burner puts out soot.
Hi there, I believe that the burner you are having a problem with, needs the inside of it cleaned, probably has alot of dust inside, or some material is in/on the orifice where the gas enters, you could also have an alignment problem with the orifice, causing a disturbance in the flow of the gas/air mixture. In addition it sounds like you may have a gas pressure problem, you should contact your gas supplier to have it checked, or call your local service company. Hope that helps, and thank you.

Carbonmonoxide is produce through the combustion products. If you have a crack in your heat exchanger it can spread CO though out your space. VERY VERY VERY VERY DANGEROUS THIS CO WILL KILL YOU!!!!!!!!!
Check for blockage in the flue pipe or improper flue design resulting in inadequate venting. One way to quickly determine a venting issue is to visually observe the flame on the burn tray. It should NOT be yellow and should burn evenly across the burner. There should NOT be any areas of the burner that appear to burned or deteriorated. Look for evidence of leaks,
You may need to dismantle the top section of the heater to visually inspect for sooting. You may need to inspect the flame sensor mechanism (if applicable) for dirt or sooting.
If it is determined that your exchanger is sooted up, you have a blockage in the flue pipe or improperly designed flue.
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.
Low gas pressure will produce low flame quality (yellow flame). Check and remove any dirt or soot on burner holes, and orifice Burner flame not going inside the fire tube could be due to soot or carbon build up inside the fire tube blocking the flame path, check the inside of the fire tube, if considerable amount of soot is seen, better have them removed. Yellow flame will cause a lot of problem on fryers if not corrected as soon as possible. If you have doubt on your gas regulator, better have a qualified service technician to check it.
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
