Hello, I posted a similar question in another section of the forum earlier, before I saw a fireplace specific area ... sorry about that rookie mistake.

I have moved my Heat-n-Glo 6000 GDVFL and I am now looking for a piece of extension pipe. I need a 9 or 12 inch heat-n-glow direct vent pipe length, but in the old style sizes with a 5" inner and 8 5/8 outer (not the regular 8" DuraVent sizes available today). I think the part numbers are DV-09D or DV-12D. Does anyone have anything like that, or access to it, or can point me in the right direction?

Thanks for the help.
