The 'gas ON/OFF safety valve' knob has 4 positions
OFF
Low
Medium
High
You turn it to High when lighting. After main flame is lit you can leave it on High if ambient air temps are above 80*F (or if you have open door issues-----door being opened a lot).
If contents get too cold you can lower temps by using the other positions (Low/Medium) which will regulate the size of flame accordingly.
Main flame stays lit until you turn gas off or a failure occurs.
Is it time for your medication or mine?
