Assuming that you have a hi effeciency system, condensation in flue gas is allways happening. Pipes should be pitched back toward boiler. What is the Make & Model? If you are talking about a 140* ret. water temp, That's quite a Temp split if your supply is 180 average temp...

    checking for condensation in noncondensing boiler

    My boiler needs an inlet temp of no less than 140, or condensation will occur, which would cause problems. Currently, I only have a temp gauge on the boiler outlet (will be adding one to the inlet). How can I tell if I'm getting condensation of flue gasses? There is a clear plastic tube in the direct vent flue that has a tiny amount of liquid in it. If we were getting flue gas condensation, would this tube be filling with water? How else could I check for significant condensation?
