Power Failure
In the event of a power failure, only the standard Star
®
burners can be lit manually. It is necessary to light each
standard burner individually (see also page 15).
If the range's cooktop is being used when the power failure
occurs, turn all of the burner control knobs to the OFF
position. The standard burners can be lit by holding a
match at the ports and turning the control knob to the HI
position. Wait until the flame is burning all the way around
the burner cap before adjusting the flame to the desired
height.
The four ExtraLow
®
burners on the outer sides cannot be
used during a power failure. Be sure to turn them OFF if a
power failure occurs because they will not turn back on
until the control knobs are turned OFF and then turned
back on again. See “WHAT TO DO IF YOU SMELL GAS”
on page 1.
If you have low gas pressure, contact your gas company.
