Surface Cooking
Air Adjustment
An air adjustment shutter for each surface burner
regulates the flow of air to the flame. When the right
amount of air flows into the burner, the flame will
be steady, relatively quiet and have approximately
3/4-inch sharp blue cones. This is usually the case
with factory preset shutter settings.
With too much air,
the flame will be unsteady,
possibly won’t burn all the
way around, and will be
noisy, sounding like a
blowtorch.
With not enough air, you
won’t see any sharp blue
cones in the flame, you
may see yellow tips and
soot may accumulate on
pots and pans.
To adjust the flow of air to the burners,
rotate the shutters to allow more or less air into
the burner tubes as needed.
How to Select Flame Size
Watch the flame, not the knob, as you reduce heat.
The flame size on a gas burner should match the
cookware you are using.
FOR SAFE HANDLING OF COOKWARE NEVER
LET THE FLAME EXTEND UP THE SIDES OF THE
COOKWARE. Any flame larger than the bottom of the
cookware is wasted and only serves to heat the handle.
Top of Range Cookware
Aluminum: Medium-weight cookware is
recommended because it heats quickly and evenly.
Most foods brown evenly in an aluminum skillet.
Use saucepans with tight-fitting lids when cooking
with minimum amounts of water.
Cast-iron: If heated slowly, most skillets will give
satisfactory results.
Enamelware: Under some conditions, the enamel
of some cookware may melt. Follow cookware
manufacturer’s recommendations for cooking methods.
Glass: There are 2 types of glass cookware—those
for oven use only and those for top-of-range cooking
(saucepans, coffee and teapots). Glass conducts heat
very slowly.
Heatproof Glass Ceramic: Can be used for either
surface or oven cooking. It conducts heat very slowly
and cools very slowly. Check cookware manufacturer’s
directions to be sure it can be used on gas ranges.
Stainless Steel: This metal alone has poor heating
properties and is usually combined with copper,
aluminum or other metals for improved heat
distribution. Combination metal skillets usually work
satisfactorily if they are used with medium heat as the
manufacturer recommends.
