The ornamental design for a round flame heater, as shown and described.
|
FIG. 1 is a front side view of a round flame heater showing my new design;
FIG. 2 is a left side view thereof;
FIG. 3 is a right side view thereof;
FIG. 4 is a rear side view thereof; and,
FIG. 5 is a top plan view thereof.
A bottom view is omitted because it is plain and unornamental and forms no part of the subject matter of the claimed design.
The broken line showings of FIGS. 1-4 are environmental only and not part of the claimed design.
In the drawings, the broken lines depict unclaimed subject matter only and form no part of the claimed design.
