We are installing a chimney in a two story house. We got a Selkirk flat ceiling support kit. We have the finish ceiling support installed and started running the triple wall pipe on the second floor. However I’m wondering what is supposed to support the chimney to keep it from being wobbly. It’s got a decent amount of wobble to it. The attic insulation shield has enough room to the let the chimney wobble and the roof flashing has air space between it and the pipe so that wouldn’t keep it stable either. So what keeps the chimney stable? Is it the roof support kit? Or am I completely missing a vital component?
 
If you need help, ask. I could get a picture as well of a install if you need one.
 
What brand of chimney pipe is this? Does the chimney pipe brand match the ceiling support brand? Will there be a roof brace when all is done?
 
I don't recall Selkirk making a triple wall pipe. That's why I asked. I saw the posting in the other thread but haven't used the Rockford flashing. There didn't appear to be enough of a lip to crimp it to make it smaller. Were you able to contact them?
 
Oh maybe I am mistaken that’s it’s triple wall. It’s class A pipe, the stainless steel stuff, 2in clearance to combustibles.

And yes, I did talk to rockford and they said that there was supposed to be that space between the pipe and the flashing.

Does the manufacturer call for bracing at set intervals. Most i have worked with do.
 
Well I had to do some research, but I found it! Chimney needs to be supported at 8ft intervals. Thank you. I do not like Selkirk’s documentation. It could just be me, but I find that I really have to look for the right information and some of it raises more questions than answers.

Ask away. It's better to ask ahead than to find out a mistake later on.
