Enhanced Thermal Transfer: The microchannel technology maximizes surface area contact

this component ensures a steady pilot flame is established before the main gas valve opens

ensuring that electrical connections remain isolated from the chassis to avoid short-circuiting during the ignition cycle

This weatherproof kit is purpose-built for high-torque applications

Resideo RRD6 Damper 321702-401 Enhanced Thermal Transfer: The microchannelThe Resideo RRD6 Damper is a precision engineered 6 inch retrofit round damper designed for seamless integration into existing rigid or flexible ductwork. This HVAC zoning damper utilizes a 24Vac, three wire, power open power closed floating actuator, providing superior control over airflow compared to standard spring return models. Built for high cycle reliability, the RRD6 features a robust Resideo damper motor that maintains position without
