American Dryer Corp ADS-464 manual Heat Reclaim ER Settings

The dryer is equipped with a pneumatically operated heat reclaimer damper, which when opened, will recirculate approximately fifteen percent (15%) of the dryer’s exhaust air.

The heat reclaimer damper is closed until ignition of flame has been established. Then, the damper piston is actuated, opening the dampers recirculating fifteen percent (15%) of the exhaust air back over the gas burner and into the tumbler (basket). The damper remains open for the rest of the drying cycle. On cool down, the damper closes, exhausting ALL of the 13,000 cfm which ensures a fast cool down of the load.
