Flappers for AQ1 and AQ4 Power Vent Kits

Both the Bosch AQ1 and AQ4 power vent kits now come with the flappers installed from the factory. In the past the flapper came separately and the Installer had to assemble it.

If you need to differentiate between the old and new versions please use the job code on the carton label as follows:

Vent Kit	Old version	New version
AQ1	05110925	09140910
AQ4	07300912	11030908
