Purchased a used gas oven yesterday. The top burners are working fine, but the oven is sooting up. We live in the country and use propane, but did not receive any additional orfice or instructions. In the past, I have had to change orfices to seitch from natural gas to propane, but this one seems to not give an option. Any suggestions?

Hi,
You are getting too much gas or not enough air to the burners... check the air shutters and make sure they are all the way open and if so then cut back the gas pressure at the gas valve...

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

I am not sure. However, people in our area of sc, have had burner problems because a local utility added propane to their natural gas because they got it a bargain. guy

The pilot light must be lit and stay lit before you will have any propane coming into the oven. This is a safety feature.

Propane burns very dirty,I bet the burner and pilot are clogged with soot.In techinical terms the sound your hearing is blowback.If you check the burner/pilot you will likley see black soot,remove them and clean with soap and water.

On top of that safety valve is a nut. Get a good fitting wrench. Turn on the oven and use that good fitting wrench on that nut. Turn it counterclockwise till the flame comes up about midways of the flame spreader. Don't get the flames too high. Midways of the spreader now. LOL

clean your orifaces.

Also make sure that it's the correct stove for your gas type. If you're using a NG stove on Propane, you're wrong. It's making a lot of soot, and could potentially blow up your house. Stop using it until you're sure.

too much air on top burner ,delayed ignition on oven ,ignitor not lined up properly or check gas presure may need regulator adjustment or replaced. gas 784

You cannot afford to take chances with gas of any kind, I must first suggest that you get a registered expert to sort out your problem. because you need to know and be sure that there is gas in your bottle, that you have the correct regulator and pressure, that the oven is set up for bottled gas as the jets are different sizes to normal town gas but all these measures can have disasterous effects if you get it wrong
