Adapting PVC to metal exhaust

[mamou]

I just got a new Infinity installed and need to know if there is an adaptor to go from the new PVC exhaust pipe to the old metal axhaust pipe. It is a propane furnace in case anyone is wondering. If we can't find it we will be forced to change out the stack going through the roof. Not that big a deal but I would like to avoid it if I can. This is a new home so everything is still new and not rusted or anything. Code made us change the unit out so that we had combustible air feeding straight into the unit. Any help would be appreciated. If you know of a part a part number and where to get it would be great! Thanks

As discussed in another thread, you'll need to get a concentric vent from Carrier. You can't vent condensing furnace in metal. Well, you can for a while, but the metal will disappear soon (plus it's not approved by MFG). :)

Ok thanks. Good to know.
