    The type of burner and the shape of the flame has a lot to do with this.     ... You don't want to be so close as to disturb the inner blue cone of the flame.   But 1.5" to 2" is a good rule of thumb for most round or tube cooking  burners.

    You can start with the burner manufacture.  They should have recommendations for best use practice for their burners.    ....    What are you doing?    .... building your own burner; or buying used burners   ... You may have to experiment to find the correct clearance.   Check the height of flame when the burner is at high heat.  Then set the clearance so the bottom of the pan is in the hot zone of the flame.

    I am thinking of building a LP cooker/steamer that would be a novelty type. Just ideas so far.

    here is a link to some burners and descriptions.    Note each one give the 'optimum' distance from top of burner to bottom of the heated surface.  Most 'high heat', 'high pressure' burners are 3" to about 5" and the flame is usually straight up.    ... Low pressure burners with lower clearance, the flame is usually horizontal and the burner has a small 'lip/flange' just above the flame.  Low pressure burner with a straight up flame, the clearance is about 3".   http://gashosesandregulators.com/castironburners.html
     
    The burner listed as 'LPCAST' (abt 10 or 11th down) is the type generally used on most Hotdog carts and requires 4" clearance to bottom of pans.
