The AQ1 can not be used as a substitute for the AQ4.

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)
