The TAPCO 481819 is a bonnet assembly designed for CP Valley applications. A bonnet assembly forms the transition between a furnace heat exchanger and the supply air duct system, directing conditioned air from the unit into the distribution network. This component is typically installed by licensed HVAC technicians as part of a furnace installation or replacement service. The 481819 provides a structural and air-sealing interface that supports proper airflow delivery throughout the connected duct system.
The TAPCO 481819 is suited for residential heating system installations where a CP Valley bonnet configuration is required. It is used during new equipment installations and equipment changeouts where the existing bonnet assembly must be replaced to maintain system integrity and airflow efficiency.
Designed as an OEM-style replacement bonnet assembly for CP Valley furnace configurations requiring this specific bonnet style.
Installation should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power and shut off the gas supply to the furnace before beginning work. Ensure all joints and seams are properly sealed to prevent air leakage into unconditioned spaces. Work should comply with applicable local mechanical codes and ASHRAE standards.
