I just installed a new gas cooktop to replace our old one. It is a GE
JGP336BEDBB 30 inch Glass cooktop. I got it installed and everything
seems to be working well, but I am concerned about some yellow flames.
If I turn it on without anything sitting on the burner it has periodic
yellow flickers. If I sit something on the burner like a tea kettle
it has more yellow flames. From reading the installation instructions
I should have no yellow flames at all. Did I do something wrong? Is
this normal? Does it need to be fixed?
BTW: this is Natural Gas

Not enough air or sodium will cause the flame to turn yellow. Dirty
vent holes may cause a yellow flame, but yours is new. Is there black
soot on the bottom of the kettle? Does the flame turn yellow when the
hood fan is on? Have you contacted GE customer support?
It may have an adjustable air control for the flame. It may need to be
adjusted. It also could just be that it is burning off contaminates from
the burners and it will go away. I would not be too concerned if it is just
a few flicks.
Small periodic flickers of yellow (or to me, orange) seem to be normal on
all of my gas appliances: stove, furnace, water heater. Here in Washington,
DC the amount of orange seems to vary by the season. Like another poster
mentioned, I attribute this to impurities in the gas. Natural gas comes from
lots of different sources, and large quantities are stored locally for
winter demand. I think this accounts for the variations.
If your old cooktop was also gas, I would think that would be a good
reference as to what a normal flame looks like. Coming to gas for the first
time from electric, one might not have a reference point.
If your flames truely do have yellow flickers rather than orange (meaning
the yellow like a candle flame vs. orange like a pumpkin), then I would tend
to think something is wrong. I've never seen what I would call yellow on any
of my gas appliances.
Occasional yellow flickers are no problem. However, any steady yellow
flames indicate too much gas in the gas:air ratio.
Gas appliances use a venturi system to inject air into the gas stream,
and your gas pressure may be lower than 'normal', meaning you need a
larger air proportion. This is generally a simple adjustment (but don't
ask me how, as I am stuck with an electric range).

Read the instruction and go to the section where it says about setting the
type fuel your using on the stove. There is switches that will let you use
it on Propane and then switch to natural gas by a flip of a switch to
convert it to natural gas. The instruction will explain all about this and i
feel you will find the problem with this section being read.
Turtle, our Kitchenaid gas cooktop didnt have any switch. It DID have a
reversible centerpiece in the regulator that you flipped over and
reinstalled for Propane VS gas. We also had to buy and install the orifice
conversion kit as they are different sizes.
