Typical Flame Characteristics

The burner flame should be blue in color and stable with no 
yellow tips, excessive noise or fluttering. It should burn 
completely around the burner cap.

Foreign particles in the gas line may cause an orange 
flame during initial use. This should disappear with use. 
Check burner to make sure port holes are not obstructed. If 
the ports are clogged, see “Before Calling for Service” on 
page 17.

NOTE: 
An audible “pop” may be heard when the burner is turned 
off manually, or when cycling in the ExtraLow® zone 
(SGSX models). The “popping” may be louder with LP gas 
than with natural gas.

Cooking Suggestions (For Best Results)

•

Use a lid to keep a more constant cooking 
temperature.

•

Use proper cookware. (See “Proper Cookware” on 
page 13.)

•

Center the pan over the burner before turning the 
burner on.

•

Refer to the “Surface Burner Cooking 
Recommendations” chart on page 11 for suggested 
settings.

ExtraLow® (XLO)

 

Techniques

•

Use a higher XLO setting if the pan is uncovered.

•

Check the food occasionally to see if the control knob 
should be turned to a lower or higher setting.

•

It is normal to stir food occasionally. This is especially 
important when simmering for several hours, such as 
homemade sauce or beans.

•

Simmer bubbles may not be seen when the flame has 
cycled OFF.

•

While the flame is ON, there may be bubbling. There 
should be at least steam and a slight quivering of the 
liquid’s surface.

•

The quantity and type of food affects which setting to 
use.

•

When lowering the flame setting, adjust it in small 
steps.

•

If a setting is too low to hold a simmer, bring the food 
back to a boil before resetting to a higher heat.

•

If an oversized pan is used, the simmer action may 
occur more in the center. For even cooking, stir the 
food around the outer edges into the food in the center.

Yellow Flames:
Further adjustment is required. 

Yellow Tips on Outer Cones:
Normal for LP Gas.

Soft Blue Flames:
Normal for Natural Gas.

If the flame is completely or mostly yellow, verify that the 
regulator is set for the correct fuel. After adjustment, 
retest.

Some yellow streaking is normal during the initial start-
up. Allow unit to operate 4-5 minutes and re-evaluate 
before making adjustments.
