ABSTRACT:
A protective collar means for surrounding the lower periphery of a cylindrical water heater. The collar means comprises a cylinder attached at the top and bottom edges to flanged and grooved rings for keeping the cylinder stable. The collar means may be easily assembled by placing the cylinder inside the flange of the lower ring and placing the flange of the upper ring on top of the cylinder. The collar means is preferably secured by a plurality of springs, which attach to the upper and lower rings to keep the collar means assembled. The collar means is spaced away from the walls of the water heater so as to ensure adequate ventilation of the air space surrounding the water heater, but is close enough to contain any fires or explosions that may occur near the gas flames.
