Installation
Instructions May be installed in new or existing ductwork between the source of noise and the register emitting noise. The best location is as close as possible to the source of noise, but not closer than 3 feet. The unit may be positioned so that either end faces toward the furnace. It is recommended that the unit be installed using sheet metal screws and standard metal duct support brackets (not supplied). The DucTMuffler™ may cause damage or injury should it fall. Finish the installation by sealing the joints with good quality aluminum foil duct tape.
