google apps - How do I remove gapps from CyanogenMod

I installed CyanogenMod 11 on my HTC One with CyanogenMod Installer. So I got also the google Apps (gapps) on my device. But I need a CM11 without gapps. I did then the following without success:

1. copy cm-11-20140308-SNAPSHOT-M4-m7.zip to /sdcard/


2. boot to recovery mode -> recovery -> ClockworkMod Recovery v6.0.4.6:


3. "wipe data/factory reset"


4. "install zip" choosing the zip-file


5. 
   

   "reboot system now"

   
   

   So I got a new CM11 but with gapps still installed.

   
   

   What should I do in addition to "wipe data/factory reset" to get rid of this apps?
