Description
The Field Controls 46487501is a precision-engineered vent damper crafted to seal off idle gas vents and automatically reopen when heating is needed. This helps preserve indoor warmth, reduce heat loss, and maintain efficient natural draft—all while increasing the safety and performance of your boiler system.
Features:
- Operates with all 24 VAC, 60hz intermittent ignition and standing pilot ignition systems.
- Stainless steel construction provides superior corrosion resistance.
- Damper operation: power opens in 15 seconds, power closes in 15 seconds. Power is off at damper motor when it is at rest.
- Hold open switch allows damper to be placed in an open position and taken out of service to assist with trouble shooting appliance problems.
- Keyed wiring harness connector plug installs only one way, preventing incorrect wiring connection.
- Dual safety switches allow the burner to fire only when the damper is in the open position. This unit will not interfere with existing appliance safety controls, when properly installed.
