5 HEALTHY HEARTH GUIDE OPEN HEARTH Products & solutions
Field Controls Air Since 1927, our focus has been the movement and control of air inside the home. Field Controls is the HVAC leader in residential appliance venting, combustion air supply, and comprehensive indoor air quality. Our expertise in air movement and control allowed us to develop the Flue Sentinel® line of products specifically for the home’s focal point - its hearth. Flue Sentinel is now available in damper only, fan only, and fan-damper combinations.
OVERVIEW Flue Sentinel® Flue Sentinel,® the open hearth solution. For decades, we have been working to make our homes more energy efficient to conserve fuel and reduce energy costs. Loss of heat through an open chimney has become a concern in this energy conscious environment. Glass doors attempt to solve this problem but eliminate the hearth’s natural warmth and ambience. Flue Sentinel® allows for open hearth construction and eliminates the need for glass doors.
Healthy Hearth OVERVIEW The Flue Sentinel® Healthy Hearth Flue Sentinel® Damper Effectively closes the chimney when the hearth is not in use, preventing heat loss and downdrafts. OR Flue Sentinel® Chimney Fan with Automatic Damper Fan provides constant flow of air to safely exhaust fumes. Damper closes when not in use to conserve energy. Hearth Combustion Air A reliable, dedicated source of combustion air keeps the fire burning efficiently without taking air from within the house.
OVERVIEW Healthy Hearth A Healthy Hearth and Home A Flue Sentinel® and open hearth are part of a well–designed home. A healthy hearth with Flue Sentinel is effectively sealed, maximizing energy efficiency by keeping the warm air in when not in use. The sealing of the dampers also eliminates any potential negative impact on the home’s designed ventilation and air balance. Damper Flue Sentinel dampers automatically open and close the hearth’s vent opening on demand.

Chimney Fan with Damper FOR GAS FIREPLACES CHIMNEY FANS All New! Introducing the Flue Sentinel Chimney Fan with Automatic Damper. This all-in-one includes a virtually air-tight flue damper with a heavy duty fan and chimney cap in one convenient, high performance package. The unit eliminates the need for glass doors on a hearth to conserve heat, and can save as much as 30% in energy costs that would normally be caused by heat loss through a chimney with a traditional damper.
Chimney Fan with Damper FOR GAS FIREPLACES How It Works When there is a call for fire, the Flue Sentinel® Gas Controller automatically opens the flue damper and engages the chimney fan. Once draft has been proven and the damper is fully open, the gas logs are allowed to light. When the fireplace is turned off, the fan is turned off and the damper automatically closes, trapping heat in the chimney.
Automatic Flue Dampers FOR GAS FIREPLACES FLUE DAMPERS For a beautiful, open hearth gas fireplace, you need a Flue Sentinel®. The Flue Sentinel is an electronic damper that automatically opens when you turn on your gas logs and closes when you turn them off. It’s installed at the top of your chimney so you never see or hear it operate, but you will immediately notice the difference. No more cold drafts coming down the chimney and no more heated air escaping from the chimney.
Automatic Flue Dampers FSE Series FOR GAS FIREPLACES How It Works When there is a call for fire, the Flue Sentinel damper opens to allow airflow in the chimney. Once the damper is fully opened, the controller allows the gas logs to fire. When the logs are turned off, the damper closes. FLUE DAMPERS Flue Sentinel® FSM and FSE dampers are ICC approved as an alternative for glass doors on fireplaces.

Chimney Fan CHIMNEY FANS For Wood & Coal Fireplaces The Type C Chimney Fan is the solution to preventing smoking fireplaces. It provides negative pressure to overcome the effects of wind, cold chimneys, insufficient chimney height, and downdraft. It is designed for wood or coal fireplaces and is available in four sizes: 6", 8", 10", and 13". It is insulated to withstand peak temperatures up to 1300º F and operates continually at 900º F without overheating the motor windings or bearings.

Combustion Air Unit FOR GAS FIREPLACES The Combustion Air Unit The CAU combustion air unit is an intake air hood and damper combined into one compact unit. The CAU opens automatically to provide air for combustion in the fireplace. Its compact design is ideal for hearths located on an exterior wall of the home.
Combustion Air Damper FOR GAS FIREPLACES Combustion Air The Combustion Air Damper or FAD works with an Intake Air Hood to provide a reliable source of fresh air for combustion directly to the firebox. This is ideal for fireplaces not located on or near an exterior wall. This sealed damper opens when the gas logs are turned on, allowing fresh air to enter the firebox as needed for combustion. When the logs are turned off, the damper closes.
Fresh Air System™ INTEGRATES with optional sensors and fans for additional benefits WHOLE HOUSE Central Fan Integrated Ventilation (CFIV) Whole House System A healthy hearth can draw a significant amount of air when the fire is glowing, causing negative pressure within the home. A Flue Sentinel can interface with our Fresh Air System to supply make-up air or ventilation air for the home through the HVAC system whenever the fireplace is running.
Make-Up Air System WHOLE HOUSE Whole House Make-Up Air System A simple, economical method to provide make-up air, this pressure-activated damper opens automatically when there is a need for additional air in the home. Since there is no motor, it works without electricity or the need for a separate control. It has an adjustable gate to control the amount of air flow.

Troubleshooting 24v & MILLIVOLT UNITS Basic Sequence of Operation for 24v Units When the fireplace is turned on, a 24v signal is sent by the fireplace control to the damper controller. The damper controller motor then rotates the damper blade, which is indexed to a cam, to the open position to allow products of combustion to pass through the flue outlet. The cam proves the damper is in the open position and switches 24v from the motor to the main gas valve or ignition system, which fires the main burner.
Troubleshooting 24v Troubleshooting Chart: 24 Volt Problem Damper won’t open. Possible Causes Action No power or insufficient power at damper. Check the voltage between the Black and Brown wire. This should be the same voltage as the output of the transformer. If this voltage is zero or below 20 volts AC check the connections and the power to the transformer. No signal to damper and the switch or remote is in the on position. Check the voltage between the Orange and Black wire after the switch.
Troubleshooting MILLIVOLT Troubleshooting Chart: Millivolt Problem Damper won’t open. Possible Causes Action Polarity reversed from thermopile. Check to make sure that the positive wire from the thermopile is connected to the THTP position on the gas valve, and the negative side of the thermopile is connected to the TP position on the gas valve. If this is reversed the Flue Sentinel will not operate. No voltage on Orange wire. Make sure switch or remote control is in the on position.
Troubleshooting MILLIVOLT Troubleshooting Chart: Millivolt Problem Possible Causes Action (Continued) Damper opens and stops in the open position but appliance main burner(s) does not fire. Signal voltage between the Black and Orange wire is more than 1.5 volts DC. If voltage between the Black and Orange wire is greater than 1.5 volts this could cause the motor to overrun the switches. The damper will open and stop but no signal will be sent to the gas valve to open.
Wiring Diagrams FLUE SENTINEL® DAMPERS Basic Wiring for 24v Damper The wiring connecting the damper controller to the gas valve must be a minimum of 18 AWG and must be run in conduit if installed on the exterior of the chimney or required by code.
