How to Install ClockworkMod on Innos A35

I tried to install ClockworkMod via ROM manager. My device(Innos A35) wasn't listed, but I chose one that was on the list thinking that it would somehow get installed. There was a download, but when I reboot to recovery mode the old recovery software with only a few options is shown. I was thinking that rebooting to recovery mode would bring up something like this if ClockworkMod was properly installed. Can someone point to me what could be wrong? Or can someone tell me how to manually install ClockworkMod without using ROM Manager?
