you would require the 61-21368-16 or an equivalent suction line service valve sized for those dimensions

Precision Draft Regulation: Maintains stable chimney draft to prevent inefficient fuel consumption

Key Benefits Optimized Compressor Longevity: Enforces a strict five-minute cooldown period to prevent locked rotor amperage (LRA) spikes common in short-cycle scenarios

typical settings are 180V for 115V systems and 310V for 208/240V systems

reducing soot buildup and optimizing fuel consumption
