Question on Installation of double walled pipe through roof

[StanP]

Hi Everyone,

Just found this forum last week. Great site and community!

I built a log cabin last year and recently bought a 28 year old Defiant. Small structure, with a 16 by 20 footprint, with a loft over half of the floor and ceilings about 22 feet high. Your first reaction is, too much stove for the space, but I'm aware of that and intend on using windows and doors when needed. Plus the structure is hand hewn, with no chinking, so naturally a bit drafty. This is a hunting camp and will never have running water or electric.

I have a straight shot from the back of the stove up 16 feet to the roof. . Rafters are 16 inches apart on center. I thought I should use double walled pipe to reduce the heat in the cabin up to insulated pipe. My question is, what should I use? Is one brand better than the other. Which is easiest to install. Is there something I can order on line (or from a store) since I intend on doing it my self. I would really like to have someone put an entire package together of what I need. I believe the insulated pipe will need to be 2 inches from wood, so that I would cut a round hole through the roof, then put flashing on the roof, which is steel and then seal with some type of calk. How far from the roof inside the house should I start the insulated pipe? What kind of bracket or structure, would hold the insulated pipe in place. I have seen some square holes and framing used on pipe exits. Is that necessary? The pipe will exit about 2 feet from the peak of the roof. . How high above the roof should the pipe extend? I am not concerned about code, but keeping my wife and 2 boys safe when we are camping there in the summer. (I'm sure I will be alone in the winter. )

thanks

Stan

Selkirk Metalbestos pipe and roof support "kits" have the best quality and good instructions for installation. For cathedral ceilings the pipe can hang from boxed in studs with 2" clearance to combustibles. Selkirk is expensive, but well made, safe, nice looking,secure. Total cost comes to ~ $1. per inch! :coolsmile:
We've done a few installations using Selkirk piping for ourselves and for friends. Selkirk's telescoping double wall pipe allows a hassle-free straight up pipe-to-stove install. If done correctly, the roof system has been leak-free for years on various pitches.
BTW: check out Craig's caps, neat looking for a nice finish if the SS top is too utility for you.

I used the Selkirk "SuperVent" line. It seems like a pretty good product too. SuperVent is only sold at Menard's and Lowes, which can make getting parts interesting if you need something out of the ordinary.

The Selkirk Metalbestos line is sold by independent hardware stores and other independent dealers, so you will have a better shot at getting parts ordered quickly if you need.

I asked selkirk about mixing parts from their three lines, SuperVent, SuperPro, and Metalbestos. They told me DO NOT mix them.

If your run is straight up, it shouldn't be difficult at all.

Also, look into the Simpson Duravent line of chimney products. The're more expensive than the SuperVent that I used, but it looks like a great product too.

thanks. How would you seal around the exit in the roof. I see you can buy flashing. I have a steel roof and was wondering what you would use to get a good seal.
