Below are some general appli- cation and installation guidelines for the concentric vent kit. Refer to the accompanying literature and the water heater installation manual for complete venting installation instructions.

This concentric vent termination kit may be used with 3 or 4 in. diameter pipe systems. When con- necting to a 4 in. diameter pipe system a 3 x 4 in. field supplied reducer is to be installed at the intake and exhaust connection of the concentric vent termination kit. See water heater installation and operation manual for venting specification

Dimension 211/8 in. may be lengthened to 60 in. maximum. Dimension 211/8 in. may also be short- ened by cutting the pipes, provided in the kit, to 12 in. minimum. Dimension 39 will change accord-
