Hello Bob, welcome to the forum, take a look at the various threads on the forum, you will find lots of photos of stove installations.
The basics: maintain at least the manufacturer's minimum distance to combustable surfaces, place the stove on a tile, brick, concrete or other non-combustable surface.
The flue pipe hook up should have one of the elbows be a 'tee', with one end capped. By removing the cap, you can clean out the flue pipe. Coal stoves don't need as much cleaning as a woodburning stove, but fly ash does accumulate in horizontal pipes. It is much easier to clean out through a 'Tee' than having to take the pipe joints apart.
I would recommend a barometric damper in the install. You should with that tall chimney have more than enough draft, and if you have too much, it will pull a lot of heat up and out of the stove, and cause too fast of a burn rate too. The Baro-damper will control the excess draft.
Hope this helps.
