Field Controls 46282620 Control Kit

The Field Controls 46282620 Control Kit (Model CK-20FV) is a critical interface designed to interlock a power venter with 30mV gas-fired systems. Engineered for millivolt gas valves, this kit ensures a safe sequence of operation by preventing the burner from firing until the pressure switch proves the stack is properly induced. It is specifically designed for non-standing pilot applications or standing pilot systems requiring power venting through the side wall. The control circuit utilizes the millivolt signal generated by the thermopile to verify airflow, providing a fail-safe interlock that protects against vent blockage or motor failure. Its compact design allows for streamlined installation within the mechanical room, ensuring side-wall venting compliance for older or high-efficiency atmospheric equipment transitioning away from standard masonry chimneys. Contractors rely on the CK-20FV for its precise differential pressure sensing and robust construction, maintaining consistent Draft and safety without complicating the low-voltage control string.

• System Compatibility: Seamlessly integrates with 30mV millivolt gas control systems and Field Controls power venters.
• Safety Interlock: Ensures the burner cannot initiate combustion without verified mechanical draft, preventing flue gas spillage.
• Reliable Operation: Uses high-quality components to withstand the heat and cycling of domestic gas-fired water heaters and boilers.
• Simplified Wiring: Designed for straightforward field wiring between the gas valve, thermocouple/thermopile, and the vent motor.

Can the CK-20FV be used on 24V furnace systems?
No, this kit is specifically calibrated for 30mV millivolt circuits. Using it on a 24V system will damage the control components; a 24V-specific kit like the CK-63 should be used instead.

What happens if the power venter motor fails?
The CK-20FV monitors the pressure switch. If the motor fails to move enough air to close the switch, the millivolt signal to the gas valve is interrupted, and the burner will not fire.

Does this kit include the pressure switch?
This kit is intended to work in conjunction with the pressure switch typically mounted on the power venter to prove draft before the gas valve opens.
