Flame Description
The burner flame color should be blue with no yellow on the tips. It is not
uncommon to see orange in the flame color; this indicates the burning of air-
borne impurities in the gas and will disappear with use.
With propane (LP) gas, slight yellow tips on the primary cone
are normal.
The flame should burn completely around the burner cap. If it doesn’t, check
that the cap is positioned correctly on the base and that the ports are not
blocked.
The flame should be stable with no excessive noise or fluttering.
Cookware Recommendations
CAUTION
Food packaged in aluminum foil should not be placed directly on
the burner grate. Aluminum foil can melt during cooking.
Do not let plastic, paper or cloth come in contact with a hot burner
grate. They may melt or catch fire.
Never let a pan boil dry. This can damage your pan and the cooking
surface.
Professional quality pans with metal handles are recommended because plastic
handles can melt or blister if the flame extends up the side of the pan. Profes-
sional quality pans are found at restaurant supply stores and gourmet specialty
shops. All cookware should have these characteristics: good heat conductivity,
good balance, correctly sized base diameter, a heavy, flat base, and a proper fit-
ting lid. For best cooking results the flame should be contained under the bot-
tom of the pan.
Aluminum and copper are pan materials that conduct the heat quickly and
evenly. These metals are sometimes attached to the base or in the core
between stainless steel.
