Field Controls 46282641 Control Kit

The Field Controls 46282641 Control Kit, specifically model CK-41F, is an essential interface for integrating a power venter with 24Vac gas furnaces, boilers, unit heaters, and water heaters. Designed for seamless interlock safety monitoring, this kit ensures the appliance burner cannot fire unless the power venter is operating at the correct static pressure. It features a high-sensitivity fan proving switch (diaphragm-style pressure switch) and a specialized electronic post-purge timer that clears combustion gases from the flue after the heating cycle ends. This 24Vac control circuit integration is critical for maintaining draft integrity in negative-pressure venting scenarios. Whether performing a side-wall venting retrofit or replacing an existing power venter relay, the CK-41F provides the necessary draft proving functionality required by code to prevent backdrafting and ensure proper flue gas evacuation in residential and light commercial atmospheric gas applications.

• Universal 24Vac Compatibility: Engineered to interface with standard 24V control transformers in furnaces, boilers, and water heaters.
• Enhanced Safety Interlock: Prevents gas valve activation until the pressure switch confirms sufficient draft.
• Adjustable Post-Purge: Integrated timer allows for a customizable delay to ensure all products of combustion are safely exhausted.
• Field-Proven Reliability: The gold-standard solution for CK-41F control kit replacements or new side-wall venting installations.
• Simplified Wiring: Features clearly labeled terminals to reduce bench time and ensure accurate HVAC control wiring.

Can the CK-41F be used with millivolt water heaters?
No, this specific kit is designed for 24Vac gas control systems. For millivolt systems, a different control kit with a dedicated transformer or thermocouple interface is required.

What is the purpose of the post-purge timer?
The post-purge timer keeps the venter motor running for a set duration after the thermostat is satisfied to remove residual flue gases and moisture, preventing corrosive condensation in the vent pipe.

Does this kit include the pressure switch sensing tube?
Yes, the kit typically includes the pressure switch, 4-inch junction box, and the necessary aluminum sensing tubing for draft pressure monitoring.
