I've had a new 2-stage American Standard Freedom-80% furnace installed in mny home. At the same time, I had a brick mason tuck-point the chimney, install a flexible (aluminum?) chimney liner, and pour a concrete/vermiculite mixture to fill the gap between the liner and the brick. The furnace contractor hooked the exhaust duct to the 5" diameter chimney liner "stub-out."

Every time the furnace runs, condensation forms and drips out of the exhaust duct (just about where it meets the chimney liner). The flu/liner has been checked and is open top to bottom (i.e., no pinches or obstructions). Furnace contractor believes that the vermiculite insulation may have changed the thermodynamic properties of the liner, making it cooler than it should be. I'm not convinced. We live in Seattle where nightime temperatures only dip to 50 degrees this time of year.

Anyone have similar experience with the type of furnace we have (2-stage American Standard-80) or with the vermiculite insulation?

I would put a carbon monoxide detector near the furnace while it's running your contractor might not have got the flue sized right for the distance and the inducer fan motor cant push hard enough and you're letting carbon monoxide go into your houses or wherever the furnace is

I believe that it was the vermiculite mixture all along. The problem "fixed itself" about a month later -- and I didn't change anything. Only thing I could think of was that the mixture finally set up completely and all the moisture was out of it.

Nothing conclusive, unfortunately, but the water stopped dripping.

i replaced my old manual thermostat to programmable high efficiency thermostat. No I m enjoying the balanced indoor air temperature and able to save some energy consumption due to its programmable feature.
