We went through the same thing with our Greystone 29MK. So, I checked with the local dealer where we purchased it. They checked with Heartland, first response was it was prewired for one. So, we ordered one. When the dealer went to install no wires or braces in place. A later call to Greysotne engineer to find out that unless the uniit was orerdered with the ceiling fan option, then it wasn't wired or braced for one. After some discussion with the dealer, abou tthe misinformation, we had him install it, adding the bracing and wired it to the AC power already in the ceiling. We are very pleased that we went ahead and added the ceiling fan, especially since we like to be out in nature. It provides a quiet flow of fresh air in the unit. Good luck!!
