Try using the power button to wake the iMac.
OS X Mavericks: Using the power button

If you are using a wireless keyboard or mouse, check out this article:
OS X Mavericks: Wake your computer with a wireless mouse or keyboard

And for more generic troubleshooting, try this one:
OS X: When your Mac doesn't sleep or wake

where there's a section for "Your computer cannot wake from sleep" and "Your computer is slow to wake from sleep".
Best Regards,
Nubz
