The best direct vent is the shortest line to the exterior and a 3" diameter opening is what's usually needed for the double stainless steel exhaust-intake tube. How about cutting a 3" diameter opening out through the back of the existing brick chimney or a nearby wall to the outside. It needs to have a slight downward slope so the left over water in the burned propane will drip out the exhaust as well as the fumes. The exhaust pipe are somewhat movable usng extensions. It's best to depend on gravity and stay away from an electric fan driven exhaust of a horizontal concentric exhaust tube.

The Chimney Cricket in Thornton, NH is a one man business who has beeen doing this type quality work for a long time on expensive and not-so-expensive homes, all over. He is good!
