Thank you for all the responses: BeGreen, Jags, Franks and Bert.
I am feel proud and lucky to be part of this knowledgeable and helpful community we call hearth.com. I downloaded and printed the manual for the reclaimer, thanks to franks

. I now understand the correct way to instal and operate this thing as well as the dangers it presents. I installed and will maintain the unit as to maximize its capabilities and minimize its ill effects. Planning on installing a clean out T at the rear exhaust to replace the lower 90 as well as frequently checking the connectors and chimney for build up. This thing was free, so I'll at least give it a shot for the rest of the season, as long as the benefits continue to outweigh the harms. The previous had it connected to his oil furnace to take the chill off the basement. He recently replaced the furnace with one that used 5" connectors so he couldn't use this 6" reclaimer. He used it for six years with positive results. I also understand that using this with a wood burning stove will warrant more frequent cleaning.
Again, thanks for the helpful answers and burn on!
