ABSTRACT:
An installation jig and method for installing the spout casting that eliminates the need for using a thick layer of refractory as previously done. The installation jig is formed from a threaded rod with a rectangular plate transversely fixed to one end of the rod and a second shorter, rectangular plate received on the rod at a distance from the fixed plate. A locking collar is received on the rod adjacent the shorter plate on the side remote from the fixed plate. The larger fixed plate is inserted into the boiler from the outside and is caused to bear against the tube surface. The smaller plate and locking collar are used to hold the casting in place until the casting is fixed in position by the installation of the spout.
