Centrotherm 4" (110mm) steel connector to provide reinforcement at joints to support loads of 99 lbs

JOINT CONNECTIONS • Each female-end of every InnoFlue® vent length or component features a factory installed gasket. Before assembly, make sure gaskets are in place correctly. • Measure the depth of the female socket. Mark* the male-end of each component just shy of the depth of the female socket from its end. • Place a thin layer of Centrocerin, a water based lubricant onto the male end of component 2 for ease of assembly. • Slip a Connector Ring over the male end of component 2 so that it can grip the gasket bead of component 1. • Push and twist male end until properly seated in component 1, aligning the mark* with the top of the female end. • Clip the Connector Ring onto the gasket bead to secure the two components to each other. NOTE: to meet requirements of UL-1738 & ULC-S636, InnoFlue® Vent Systems of  2", 3", 4" and 5" diameters must utilize Connector Rings.
