On mine, what I have found is that immediately after the burner comes on,
some flue gases do escape through the air gap.  But the column of air in the
chimney quickly warms up and pulls a draft sufficient to suck air in through
the gap.

NOW you tell me!  Those escaping flue gases also melted the insulation <G>
