3.2 Burner Characteristics
If one or more burner blows out, the respective igniter electrode
automatically re-ignites the flame.
At each burner port the flame should burn completely around the
burner cap.
It is normal to hear the following during burner operation:
•
A slight sound that is associated with gas combustion and ignition
•
A clicking noise every time the gas cycles, coming from the
solenoid valves of the two left burners
•
When using LP gas, a slight “pop” sound may be heard at the
burner ports a few seconds after the burner has been turned off.
NOTE: If burner characteristics are not adequate, see Burner, Flame,
and Ignition Troubleshooting, page 12 .
3.3 Flame Characteristics
Natural gas: The burner flame color should be blue with no yellow on
the tips (see Figure 6). It is not uncommon to see orange in the flame
color; this indicates the burning of airborne impurities in the gas, and
will disappear with use.
LP gas: Slight yellow tips on the primary flame cone are normal and
may appear after a few minutes. The flame should be stable with no
excessive noise or fluttering. Orange colored streaks in the flame are
produced from burning airborne debris, which is normal at startup,
and should dissipate in a few minutes (see Figure 7).
When the flame for both natural gas and LP gas is properly adjusted,
it should burn at each burner port (completely around the burner cap).
NOTE: If burner characteristics are not adequate, see Burner, Flame,
and Ignition Troubleshooting, page 12 .
