We are installing a Price Pfister Ashfield Collection 808 Series. When installing the shower handle, it does not seem to go against the trim plate. There is at least 1/2 grap. According to the picture on the box, there is not a gap. Should there be that gap? Is there something that can be done to correct it, if not?

This sounds like a proper with your water heater. If you just installed this new shower head. First take it off and make sure that the hot water valve is opening fully if that checks out then go to the water heater and make sure the pipes check out ok and also that the heater is ok. Try putting a water heater blanket on it. Also try getting some pipe cover and cover the hot water line so on really cold days or not you will have warmer water
