I am building a new pole barn shop with metal sides and I want to put my old King heater in there for a little heat. What is going to be the best way to route my pipe and not burn down the whole place and maintain as much heat as I can. I thought about getting out away from the wall a few feet going straight up about 10 feet, putting a 90 in and turning it through the wall then turn up again outside the wall and go up above the ridge height. The shop has 12 feet walls. I really hate to go through the roof because of leaks.
 
The best way is straight up. Stove drafts better & the
connector & chimney stay cleaner If the flashing is installed
correctly, there won't be any leaks.
What is your roofing material?
 
Keep in mind that for every 90 degree bend in the pipe, you are effectively reducing the overall chimney height by 2-3 feet. Also if you do go horizontal, you need a minimum of 1/4" rise per foot of horizontal.
 
The pipe you run inside is cheaper than the stuff that you run outside. Just something to think about. Oh - and straight is always better.
 
Straight up is going to run cleaner and better. Done correctly, there is no reason to be concerned about leaks when going through the roof. If it leaks it's a sign of poor workmanship.
 
Nothin new to add except that on an uninsulated barn you really want your heat source away from any walls as much as possible. That heat will just go to waste near a wall. Ideal would be smack dab in the middle of the barn without getting it in the way of your work or anyplace you need to have equipment, etc.

Don't shy away from straight through the roof. It'll keep more heat inside and will make it wayyy cheaper in the end.
 
Absolutely straight up. I second what others have said, cheaper and more efficient.
 
Jack,

My shop is a 36 X 40 pole barn with 10 ft clear at the walls. Currently have just an insulative vapor barrier at the ceiling (stops the interior rain..... more insulation planned for later ) with R15 in the walls. I'm heating it with an Englander NC30. I can get it 35 deg to 55 deg in a few hours, in the middle of winter. I located my heater so that I could keep the chimney inside, towards the roofline at one end, to keep the cost down. Here's a few pics.

I will have exactly the same roof as in gasavage's picture. I have not seen a top piece like that, but it does look as though it would work pretty well for keeping water out. I am not sure I will be able to put it out in the middle of the shop floor but I will be able to get it away from the wall some and the trusses are on four foot centers so I will just go right up between two of those.

question.....How many square feet is your building? (just curious)
 
ICC Excel makes a few flashings that will work. I just copied what ICC had done & bent my own. There are other mfrs that have similar products. Here's a few pics of what ICC has. There's a brief installation guide in their manuals.

The building will be 1500 sq ft. 30x50 with 12 feet walls, with 4:12 pitch trusses, open for now. Maybe I can put up a ceiling when I get rich.
