Can I use the cooktop burners manually during a power failure?

Yes, the burners can be ignited manually during a power failure. Turn all burner control knobs to the OFF position first, then hold a match at the ports and turn the control knob to the HI position. Wait until the flame is burning all the way around the burner before adjusting to the desired height. Note that the automatic reignition feature will not work during a power failure. (Page 10)
