High Torque Transmission: The key-to-key drive system utilizes keys on both the shaft and the hub for maximum power handling

This control board manages critical system functions

it can be used in specific hydronic heating systems where return temperatures must be tempered to prevent flue gas condensation

Technicians should verify the condition of existing seals and apply high-temperature RTV or new gaskets as specified by the service manual
