Check whether the flame spreads to all burner ports when the
burner is lit with the gas valve set to the minimum position.

setting. Check whether the burner remains lit even when the
gas valve is turned quickly from the maximum to the minimum
position. If the burner does not remain lit, increase the
minimum gas rate setting.
To adjust the minimum gas rate setting:
