Exhaust hose, riser, elbow: should I replace at same time??

[Stu Jackson]

Stu: Thank you.  I now can, but my firewall is in the way, saying the file has malware attached.  I will do this on a "sandboxed" machine.

Bill, please write to Dave Sanner (sanner att big dott  net) and ask him to look into this.  I did not have this problem.
