I’m working on installing a new chimney for a Woodstock Ideal Steel stove that I’m due to receive in November. Doing the layout from dimensions it looks like the stove pipe is going to need to be offset by about 1.5” to 2” to miss the roof truss. Do I need an offset joint to make this work or can a straight piece of pipe be used slightly out of plumb?
It will be about 5’ from the top of the stove to the cathedral ceiling support box.
I’m planning to use double wall pipe.
I learned alot DIY'ing my stove.
When I designed an expansion, I did some research on stoves and figured I had what I needed clearance wise without interfering with a seating area or office entrance area.
The mistake I made was not considering how the pipe would run out being completely new to this. I had thought I was going to run it outside originally as an option and didnt care much. I changed my mind quickly after learning how much better it would be to run the pipe inside.
It became apparent fairly quickly to me that 1. I have a main beam to content with , so if I built my office 6" smaller or gave up on the idea of a larger dining area, I could have gone straight out. Neither of which I could really correct after the fact. 2. you will always have a truss in the way. Even if you could exit and miss a truss with a pipe, you will still need to center the pipe under the ceiling support box.
This is the mistake I made, I left myself NO wiggle room forward or side to side for the stove to move towards centerline with the ceiling support box when I was designing and constructing this place.
So I had two options, 45's and a shorter run toward the office area or toward what will be the dining area. I picked the dining area because the outside pipe wouldnt be as visible from the front of the cabin, and I could work over that area easier. Also, I picked a telescopic pipe for BOTH the angle and straight legs of the pipe runs. I cant imagine how much more difficult it would have been to be precise enough to have a non telescopic pipe on the angle run.
Here's my install pictured Sorry I didnt capture the ceiling support box. It is right on the other side of that elbow at the top.
