Safety of Coax Power Inserter for Coax in attic insulation

Hi all,

I recently moved my receiver for my master bedroom from my chest to my master bedroom closet. In the master bedroom I have an HDTV connected to an H23-600 HD receiver. Prior to moving the DirecTV STB, the wall plate had an input and an output, and the technician had installed a DirecTV PI-21 Power Inserter. As he explained it, this was sending 21 volts up the coax stream to power the LNB.

Since I moved the Power inserter and Set top box, the coax carrying 21 volts back to the LNB is running through about 16" of blown in cellulose insulation. I have coax connections made up in the attic where I tapped into an existing solid coax line to feed the coax down to my master bedroom closet.

All of my equipment is working fine and I have no problems with malfunction, I just want to know if its safe to run the coax with the 21volts through it in my attic with insulation around it. There are connections made within the insulation
