Claim 13:
14. A method of using a fire pit, comprising:
introducing a combustible fuel into a burn chamber with an upper opening of a fire pit, the burn chamber having a vertical axis and being defined by an inner wall comprising an upper portion having an internally facing ventilation hole, the inner wall being disposed above a bottom wall and being disposed within an outer wall, the inner wall being spaced from the outer wall to form an air passage therebetween allowing flow of air through the internally facing ventilation hole into the burn chamber;
capturing ash from the combustible fuel while burning that falls through a fuel grate into an ash pan disposed below the fuel grate, the fuel grate having an array of holes therein for passing ash to the ash pan and for passing air to the combustible fuel disposed on the fuel grate, the ash pan being disposed below the fuel grate and above the bottom wall in a manner allowing flow of air over an edge of the ash pan to the array of holes;
increasing separation between the ash pan and both the inner wall and the outer wall by relative displacement in an axial direction to provide access to the ash captured in the ash pan.
