Can I use this as a direct vent for my wood stove? Can I connect the 6-inch stovepipe from my stove directly to this and into my chimney?

Answer:This thimble is indeed designed for installation into a masonry chimney and will allow you to pass single wall stovepipe through the chimney and into the flue. You will need to use a fireplace cement or mortar to seal the small gap between the stovepipe and the thimble, as creosote leakage can occur otherwise.

After i pass the thimble into the flue and cut it flush with the interior red brick is there anything to add to it before I put the inch pipe thru it and connect it to the stove, like a collar of some sort ?

Answer:You may choose to add a finishing collar around your stovepipe, in order to cover any potential gap between the pipe and the thimble. However, it may also be necessary to fill the gap with masonry cement or mortar, depending on whether or not your chimney is lined.
If the pipe is venting into an open chimney, you will definitely need to seal the gap with mortar, then cover it with a trim collar.
