My gas stove is orange flame - Kitchen Ranges

There is a flame adjust ring on each burner where the gas exits the inlet nozzle. Before adjusting these, be sure all other gas appliances are working ok (water heater, etc.) . If they are then focus on the pressure regulator on the stove itself. That is the part that the gas line from the wall connects to on the stove. It is most likely bad. If not then go back to each burner , loosen the screw that locks the adjustment ring, turn the burner on and move the ring back to allow more air to mix with the gas so the tips of the flame just turns from orange to blue. Tighten the screw and move to the next burner that needs adjustment.

What is the gas pressure into the stove? This is a critical measurement and should be done by the gas company.

The color of the flame indicates the ratio of fuel to oxygen.
There is a change in your environment morning to evening. Do you have a very air tight home? Perhaps over night the oxygen level is diminished. During the day people come and go, opening doors to bring in outside air. Over night the gas heater may be running more. You should get a carbon monoxide alarm monitor and have them check your furnace system vents. The stove might need a vent.

Yellow flame be concerned. Orange flame is dust and/or occurs after cleaning the burners - should go away on its own.

According to this thread:

It sounds like it is impurities in your (or more likely your suppliers) gas line. If it goes away but reoccurs semi regularly, then I would guess this is what it is.
If it is happening all the time, or you are concerned about it, call your gas company and ask them about it. I am sure they havve heard of the problem before.
Good Luck!

A <i>temporary</i> orange flame from your gas stove can also occur at peak usage times. An increase in local demand can cause a decrease in pressure in the natural gas line. If all of your gas appliances are in combustion simultaneously, this may also cause a drop in pressure, especially in older houses. If the problem persists, it is likely a dirty/clogged burner or the stove needs servicing. In general, an orange flame (on a gas combustion appliance) means incomplete combustion and carbon monoxide production.

Silver solder up all burner jets and redrill to .6 mm then reset adjusters so you get a nice blue flame with small orange tips.and oven burner to .8mm i have just done a new world 75 last week.Works perfect

Have it checked out by a QUALIFIED gas person!! Don't screw around with gas unless you want to wake up dead due to carbon monoxide poisoning or an explosion!!!! Gas is NOT a forgiving task-master.

 mine was humidifier, orange flame is minerals in the water.

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
