The FAPV Power Ventilator is an inline duct-connected fan intended for use to provide fresh outdoor air for the
purpose of meeting indoor ventilation code requirements and occupant preferences. Fresh outdoor air is brought
in through an outdoor intake air hood and ducted into the ventilator, which discharges the fresh air either by
duct connection to HVAC ductwork (see further instructions), or directly into the space to be ventilated, such as a
mechanical closet.
WARNING: Do not use the FAPV ventilator as an exhaust fan for range hoods, combustion appliances or

  • Page 4: Planning For Installation

    The air intake hood or termination must have an insect screen of maximum ¼” mesh size. The Field Controls model IAH-6 meets this specifi cation.
  • Page 5 If the outlet duct is to be connected to the return ducting of the HVAC system and the FAPV is set up for intermittent ventilation, installation of a 24 VAC powered air damper such as the Field Controls model FAD-6 is strongly recommended to prevent incoming air fl ow during periods when the HVAC fan is active but the FAPV is not active.

  • Page 6: Ductwork Installation

    NOTE: if a ventilation controller having an outdoor air temperature sensor that may be mounted on the inlet air duct is to be used (such as Field Controls model FAVC), follow the manufacturer’s instructions to mount the outdoor temperature sensor on the inlet air duct, as close to the intake air hood as is reasonably convenient, see Figures 4 and 5.
  • Page 7 Inspect the factory-installed backdraft damper vanes and their seal in the outlet collar of the FAPV fan unit and verify proper operation of the damper. Air fl ow through the FAPV will cause the damper vanes to open; spring pressure/air pressure will cause the vanes to close when air fl ow ceases or tends to go back out of the FAPV towards the inlet air hood.

  • Page 17: Troubleshooting

    Some controllers may allow suffi cient electronic “bleed voltage” to cause the FAPV to run when there is no intended call for heat. Use a dry-contact type ventilation controller if necessary, such as Field Controls models HHSC, HHSC+ or FAVC. Check ventilation controller for proper 24V ventilation output confi guration.
