Abstract
A tool is provided for removal and installation of a fire tube that extends into an opening in a wall of a heating vessel. The fire tube locates within an interior of the heating vessel when mounted thereto. The fire tube has a tube wall that defines a tube interior and has a mounting end for mounting the fire tube to the wall of the heating vessel. The tool has an elongated main shaft member having an insertion end and an opposite control end. A first support is mounted upon the insertion end that is configured for being closely received within the tube interior. A second support is mounted along the length of the main shaft member, the second support having a fire tube interface configured for engaging and releasably coupling to the mounting end of the fire tube. A lift coupling couples to the main shaft and locates between the second support and the control end of the main shaft member for coupling to a lift line. A counterbalance support carries removable weighting members, the counterbalance support being coupled to the main shaft by a counterbalance support spacing arm that extends laterally from the main shaft member.
