I have a relatively new furnace--it's about 2 years old. I'm getting water in the furnace. It's running down the flue and into the furnace causing it to rust.
My masonary chimney has a 4" stainless liner in it and a "martian hat" vent on the roof and it is watertight too. The problem is, I'm getting a lot of condensation in the flue before it gets to the chimney/liner. I have an approx. 12 feet horizontal x 3.5 feet verticle run in the basement.
I run a 20 degree temp swing 2x daily in the house in the winter, so that's a lot of opportunity for the water vapor to condense.
I'm not sure what to do to solve. Temporarily, I installed a verticle tee right off an elbow from the furnance. I wanted to create a dripleg cleanout to keep the water from running down into the furnace. This won't solve the problem long term and the flue will continue to rust and rot out.
Someone suggessted using double wall or B-pipe, but I can not find what I need at bLowes: it's 6" stainless, pricey and I didnt find elbows either.
So, what to do?
Please help
Thanks
Jason
