The Bosch AquaStar Power Vent Kit is designed to allow horizontal venting and
direct termination on an outside wall. A gas pressure sensor switch turns on the vent
fan as soon as the AquaStars burners activate. The blower fan exhausts flue gases to
the outside. The fan accepts 4 inch vent pipe. (see the Installation Manual for more info -
you can download it below)
If outside tempertures falls below 32°F you should use the Back Draft Flapper
- this is included with the AQ4.
