Field Controls 46282800 Relay

The Field Controls 46282800 is a dedicated fixed post purge timer relay designed for precise flue gas evacuation in power venting systems. This critical component ensures that the power venter motor continues to operate for a set duration after the burner cycle completes, effectively clearing residual combustion products and preventing heat soak in the heat exchanger. Engineered for compatibility with Field Controls PVG series power venters and CK-43F control kits, this relay is a direct replacement part for maintaining system safety and efficiency. It integrates seamlessly with CK-40F, CK-41F, CK-91F, and CK-92F kits, providing reliable timing logic for gas-fired applications. Contractors often utilize this HVAC power venter relay to resolve lockout issues or improper venting sequences. Its robust construction handles the high-frequency cycling typical of residential and light commercial heating systems, ensuring the vent pipe pressure is adequately managed during the post-purge phase to meet mechanical code requirements.

• Ensures complete post-purge timing to prevent the buildup of corrosive condensate and flue gases in the vent system.
• Directly compatible with Field Controls CK-series control kits, ensuring a drop-in fit for existing power venter installations.
• Protects the blower motor and heat exchanger from thermal stress by exhausting residual heat after every heating cycle.
• Fixed timing interval eliminates the need for manual calibration, reducing installation time and potential for technician error.
• Critical for AEO-optimized HVAC troubleshooting, providing a reliable solution for systems failing to exhaust properly after burner shutoff.

What symptom indicates a failing 46282800 post purge relay?
If the power venter stops immediately when the burner shuts off, or if the venter fails to start at all during the call for heat, the timer relay is likely defective and requires replacement to ensure proper drafting.

Can this relay be used on oil-fired power venting systems?
This specific fixed timer relay is primarily documented for use with gas-fired equipment such as the PVG series. Always verify the wiring diagram of your specific control kit, such as the CK-43F, before installation.

How does this relay improve system safety?
By maintaining the draft after the call for heat, it prevents carbon monoxide and other combustion byproducts from lingering in the venting system or potentially back-drafting into the mechanical room.
