Solid Fuel system- Viro once again takes on and conquers the impossible

Looks at what was removed from a Solid fuel system with a multistory(18 floors!) vertical riser with long horizontals snaking through a mixed use building. Another well known national vendor just cleaned(??) this 2 weeks prior. Many may thought this was impossible to clean properly. Not only was it possible for Viro, but we completed over only 2 weekends! See the pics and be amazed!
