As per the FIAMMA instructions try adjusting the left to right angle of the awning so that the water drains to one side by making one leg shorter. Also be sure to install the center support strut so it does not sag in the middle.
Hm... read the instructions... good idea!

I thought I was familiar with awnings from owning a 5th wheel, but never had one this style. Will do tonight!
I am familiar with angling the awning to one side to drain water, I used to use my 5th wheel awning as my carport for the beetle. Here in FL sudden downpours can rip an awning right off if not angled to drain puddles.
CalCruiser provided good advise on set-up.
Our 2007 box awning is surely not an easy push-button operation, but it does work well when attaching the lower end of the poles to the motor home. I never tried using the PC-provided stakes and ropes. When familiar with the awning, it takes about 5 minutes to set up.
Being you have a 2006, your main entry door swings freely and will hit the awning pole when attached to the motor home. I came up with a door stop utilizing a rope to resolve that, one of many little extras I did detailed HERE. Many of the extras primarily benefit the older PCs. Newer PCs have some of them implemented in one form or another.
Hm... AFAIK, we have no ropes/stakes etc. There are two legs that come down from the awning, but no sockets on the coach. (available at ~$40 each)
The door hitting the rail is no big deal, with the door that close to the edge of the awning any style will have that problem.
The problem I have is that even fully extended, the awning has 'dips' in the fabric that will puddle water. No matter what angle I put the legs at. :( And i installed the center bar, tensioned it the best I could. Made little difference.
But, as CalCruiser mentioned... INSTRUCTIONS.

Maybe I should read them before spending $1K+ for a whole new setup.
Thanks again. Sometimes I miss the obvious looking at details.
