How to use
Install the SpiroFlex VENT CLEAR HD3 HE Comfort in a horizontal orientation in a ceiling void, attic, or technical room with sufficient access for duct connections and maintenance. Connect the supply and exhaust ducts according to the building's ventilation layout, ensuring airtight joints and appropriate insulation where ducts pass through unconditioned spaces.
