Hehe, well, easy....xandrew245x wrote:That easy, huh? Another issue though, I would have the optional flue cleanout attached, I assume that counts as one 90, it would then have to do another 90 to go towards the chimney, then another 90 to go into the thimble, that is the use of 3 90s. In the manual it says no more than 2 90s.
I could however turn the wl110 so the back is facing the existing boiler, but the the problem arises that I would not have 48" of clearance to my water heater (that could be moved if push comes to shove)

As for the 3 90s, If you come off the boiler as one, and run your vent pipe to the thimble, you should be able to adjust the angle to get into the thimble with the second 90, I'm thinking. I have a 90 off the top of my boiler, and a flex couple at the thimble that allows me to slope the vent pipe upwards to exhaust.
