Using Raster Calculator to Convert 0 values to NoData in a raster?

I am using Arc 10.0........

I have 2 files... a raster made from a Polyline shapefile and a masked area from a polygon...


I am trying to use Raster Calculator Map Algebra to convert the values of 0 from blue area to NoData in the overlapping area behind there...

This expression below converts those pixels to 0..

Con("polrecl", 0, "maskdpoly")

I want to convert to "NoData" instead because I want to do statistics on the area inside the boundary only.

I tried Con("polrecl", NoData, "maskdpoly") but this doesn't work...

I am new to this stuff, can anyone assist?
