Field Controls 46487101 Vent Damper

The Field Controls 46487101 (Model GVD-6PL) is a 6-inch stainless steel automatic gas vent damper designed for 24Vac gas-fired atmospheric heating systems. This unit is a direct replacement for 240006938, Q35RE-1, RVGP-KS-6BKF, and legacy GVD-6 models. Engineered for both intermittent ignition and standing pilot applications, the GVD-6PL uses a power-open, power-close motor that completes its cycle in 15 seconds. By closing the stack during the off-cycle, it eliminates standby heat loss, prevents downdrafts, and stops conditioned air from escaping through the flue. The stainless steel construction provides superior corrosion resistance in high-moisture combustion environments. A built-in manual hold-open switch simplifies troubleshooting and combustion testing, while the keyed wiring connector ensures correct polarity and rapid integration into the control circuit. Note that this specific SKU is the damper without harness, allowing contractors to reuse existing Field Controls wiring or select a specific harness for the application.

Key Benefits for HVAC Contractors:

• Direct Cross-Reference: Replaces common OEM vent dampers including Johnson Controls and Effikal equivalents.
• Operational Efficiency: Eliminates electrical draw when the motor is at rest in either the open or closed position.
• System Safety: Proven interlock technology ensures the burner cannot fire until the damper is in a fully open position.
• Reduced Air Infiltration: Significantly mitigates cold air backdrafts during boiler or furnace off-cycles.
• Durable Metallurgy: High-grade stainless steel components withstand the rigors of atmospheric gas combustion.

Common Technical Questions:

Is the wiring harness included with the 46487101?
No, the 46487101 is the damper assembly only. If your project requires a new harness, you must purchase the appropriate Field Controls 4-wire or 6-wire harness separately for your specific gas valve or control board.

Can this damper be installed on oil-fired appliances?
No, the GVD series is strictly for use with 24Vac gas-fired appliances. Oil systems or thermal-actuated systems require different flue control solutions.

What is the purpose of the manual service switch?
The "Hold Open" switch allows the technician to keep the damper open during maintenance or startup without the burner being energized, which is essential for certain safety inspections.
