Description
Product image is representative only. Actual product may differ in appearance depending on size, configuration, and options selected at order.
Motorized flue damper for commercial and large residential vent runs from 10" to 30". Power Close / Spring Open fail-safe — the flue path is always clear on any power interruption. Belimo TFB24 actuator. Relay and end switch included on every unit. Select diameter only.
Appliance interlock is required on every installation. The appliance must not fire until the end switch confirms the HAC-F is in the spring-open (flue clear) position. Do not operate a motorized flue damper without ADP relay adaptor interlock. This is a safety requirement regardless of appliance size or application type.
✓ Spring Open fail-safe — flue path is clear on any power loss; spring operates without electricity, without control signal, without BMS
✓ Belimo TFB24 actuator — rated for the torque demands of 10"–30" blade areas under commercial flue static pressure and temperature conditions
✓ Relay and end switch included on every unit — no configuration required; relay feeds ADP or BMS, end switch confirms spring-open position before firing
✓ Belimo TFB24 field-replaceable — stocked through Belimo distributors; actuator replaces without removing the damper body from the flue run
✓ CSA certified to 12" — for 14"–30", confirm AHJ acceptance before ordering on code-required applications
✓ Need 4"–9"? — use the standard HAC-F with Hoyme drive; same SPC-F spring-open fail-safe behavior

Need an ADP relay adaptor? The end switch on this unit feeds the ADP relay adaptor input — the ADP holds the appliance off until the end switch confirms the spring-open (flue clear) position. Select by appliance voltage: ADP-0MV2-S5A (millivolt), ADP-0240-S5A (24 Vac furnace), ADP-1102-S5A (110 Vac boiler/tankless).
