Fieldpiece 46487101 Automatic Gas Vent Damper 6 Inch 24V

Product Description

The FIELDPIECE 46487101 is a 6-inch round automatic gas vent damper designed to control airflow through natural-draft appliance flue systems. Operating at 24 volts, the damper opens automatically during appliance operation to allow combustion gases to exhaust freely and closes during off cycles to prevent residual heat and conditioned air from escaping the structure. The motorized actuator cycles power-closed in 15 seconds and power-open in 15 seconds, providing consistent, repeatable performance. Licensed HVAC technicians and gas appliance service pros install this unit as part of a complete venting assembly on gas-fired heating equipment.

This vent damper is suited for residential and light-commercial natural-draft gas appliance installations where 6-inch flue pipe is used. It mounts in the flue pipe run between the appliance draft hood and the vent connector, providing a positive seal against cold-air infiltration from down drafts during standby periods. The unit ships without a wiring harness, so the installer connects it using the existing harness or a field-supplied harness appropriate to the appliance control circuit.

Key Features

• 6-inch round diameter fits standard natural-draft flue pipe
• 24-volt operation integrates with low-voltage appliance control circuits
• 15-second power-open and 15-second power-closed motor timing for reliable cycle control
• Closes during off cycles to retain conditioned air and prevent cold-air backdrafts
• Supplied without harness for compatibility with field-supplied or existing wiring
• Round shape matches standard round B-vent and single-wall vent connector sizing

Compatibility

Designed as an OEM-style replacement or new-installation automatic vent damper for natural-draft gas-fired appliances using 6-inch round flue pipe operating on a 24-volt control circuit.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified gas appliance service professional in accordance with the appliance manufacturer instructions and applicable local codes. Shut off gas supply and disconnect power to the appliance control circuit before beginning installation. The damper must be installed in the flue pipe with the actuator oriented per the manufacturer instructions and wired into the appliance low-voltage control circuit so the damper proves open before the burner is permitted to fire. Do not install this damper on power-vented, induced-draft, or direct-vent appliances.
