Have a flue pipe question for my Quadrafire 7100

The picture here shows the type of flue pipe I will be using on my Quadrafire 7100 install.Where the fireplace is going to set the flue pipe just barely hits the truss..Can I get some kind of flue pipe piece that will offset my pipe to center it between the trusses? The pipe has a collar that goes right at the top of the fireplace that has a flex line that runs outside. Its an air cooled pipe I assume. There is a sticker on the outer flue pipe that has SL348 on it if that helps. Also do I need something where the flue goes between the trusses to keep it off the trusses?

Ymurf, there is a 30 degree offset and return kit (elbows) for that sl300 air cooled pipe. It is available thru any dealer that sell HHT products like Heatilator, Quadrafire and Heat N Glo. Sl300 chimney was originally made for decorative open wood burning fireplaces by Heatilato. It's the ONLY flue u Can use on 7100. Good luck.

Thanks,I didnt know this was the only kind of flue I can use on this fireplace.
