Basics for Installing Flue Pipe on Freestanding Stove

Hi,

We have a freestanding Whitfield Advantage II that is about 15 years old. It was installed by just venting with a horizontal pipe about 3 feet away from the house.

According to the manual, this is up-to-code. But as all of you probably know, it means
1. The side of the garage that is nearest the pipe is covered in soot
2. The walkway between the garage and house is covered in ash
3. Every time the stove goes off, our room fills with smoke because there is no up-draft. (draught?)

We're having our house and garage resided (due to rot, not just the soot) and our contractor said he would install a vertical flue for us as part of the project if we supply the materials. (He has a pellet stove of his own).

He mentioned something about 3 feet higher than the top of the house.

So....

Any advice you can give me would be helpful.

What do I need? I've been reading about T junctions and pellet stove (not wood stove) end caps.

Do I just buy all this stuff at Home Depot or do I need to go to a stove shop? Or online somewhere?

What material should this be?

Anything else I need to know? I have 0 knowledge in this area. Other than what happens if you don't vent vertically.

Thanks a lot,
Susie

Hi,

Great info! I checked out the Dynamitebuys site. What's the diff between 3" and 4"? Which is typical?

Thanks, Susie

Hi,

Just coming back to this thread now after having to deal with some other issues.

Snowy, the soot problem I had was not on the side of the house that had the vent. That was all clear. But the vent was located in the walkway between the house and garage. It was the side of the garage that had soot and also the walkway. Our horizontal pipe just had a 45 degree on the end of it.

Another problem I just realized is that if I just extend the pipe vertically, it will cut in front of a window on the second floor. So I need to make it about a foot further over.

So I assume this means that I use a 90 degree where it comes out of the house to redirect it horizontally
horizontal 1 foot
T clean out (is there where I would use it or when the pipe first comes out of the house?)
vertical 19.5 foot (which will put me 2 feet above roof line).

According to Mac's post, this gives me an EVL of 22.75. So I assume this means I need to switch to a 4" pipe?

How does that work since the connection with my stove is 3"? Does this mean I need some kind of adapter that attaches to the stove but then goes from 3" to 4"?

Thanks, Susie

Also, in that image that Mac provided, it says vertical terminations require 24'. Did they mean 24"?

How do I figure out the brand of my existing vent?

Hi,

Here are some pics:



Unfortunately I waited too long to figure all this out and it looks like I'll have to buy it some place I can go to in person. The contractors are going to be ready for it next week.

But I still need to know what to buy.

Thanks, Susie

Ok, back to some basic questions.

1. On one website (http://www.northlineexpress.com/category/4PelletVent.asp) I see these different brands:
Simpson Duravent Pellet Vent
Simpson Duravent Pellet Vent Pro
Selkirk Pellet Pipe

Is the general consensus to go with the Pellet Vent Pro? From what I've read, that only requires it to be 1" away from the house, correct?


2. So the general concept is:


3" pipe goes out of my stove through an appliance adapter and then through a wall thimble.
Outside it goes into an increaser T which I can rotate 45 degrees.
4" pipe goes out the top of the T at an angle (since I've rotated it) and goes for a few feet into...
45 degree elbow.
Pipe comes out the top of the elbow and up to 2 feet above my roof
Pipe has an end cap on it.

Is this correct?

3. Can I use my existing wall thimble? Do I just caulk around the pipe? (using high-temp caulk).

4. Does the pipe come in set lengths or do you cut it to fit? In other words, if I only need the outside of the pipe to be 1" away from my house, do I need to reposition my stove on the inside to make this work or do they cut the pipe? How do the ends connect?

5. On that same website I mentioned, what they sell is 'chimney pipe.' To a newbie like me, this sounds like what you would run on the inside of your chimney. Is this the same as the normal pipe to run outside the house?

6. I see roof flashing mentioned on this site. Do I need flashing on the top of my roof?

7. The pipe will be right near where electrical wires are, but it sounds like as long as there is 1" clearance, that's ok, correct?

Guess that's it for now. Home Depot only has this stuff in season, so I'll have to get it from a stove shop which will probably be more expensive, but the contractors are going to be ready to put it in next week so I don't have time to wait for shipping if I order it over the internet. I just want to make sure I get the right stuff.

Thanks, I'm sure I'll have more questions.

OR....

am I being too paranoid with wanting to vent above my roof line?

My old setup, as you can see from the pictures, was venting out a horizontal pipe. This led to two problems: 1. we would get smoke inside when the power went out or the pellets ran out and 2. we got lots of soot on the side of the garage (the vent was between the house and garage).

Would it be good enough if I just used a regular Tee and went straight up a few feet? Would that create enough draft to solve both of the original problems?

The only reason I wanted to divert horizontally was to avoid passing the pipe in front of the window on the second floor, but if I just went up a few feet instead of up to the roof, this wouldn't be an issue. It would be cheaper too, and I might be able to stay with a 3" pipe (I'll have to evaluate the EVL again). But now that we got brand new siding put on, I really, really don't want to cover it in soot.

Thought I'd come back and post my results.

I now have a new flue pipe that goes up to my roof. Haven't tried it yet because I didn't get it in while the weather was still cold.

I bought from http://www.northlineexpress.com after researching lots of different websites. They had the cheapest prices. (Another website had cheaper prices on individual items, but wanted to charge me $199 for shipping. Northline Express had free shipping so it ended up much cheaper). They also delivered very quickly.

Their website is a little slow and their search didn't work very well, though, but be patient. A little trick--navigate to your first item through their menu choices. But after that, just change the end of the URL to the next product number you want, if you know it. It's a much quicker way to get to all your items.

Note: I did first email Eric from Kingsman Stoves as a previous post recommended, but he wasn't interested in my business enough to call me back. He emailed that he would call me on a certain day at a certain time, so I made sure to be home from work early. But he never called or emailed again.

I ended up with what the previous posts recommended: PelletStove Pro. 3 inch coming out of my stove into a conversion clean-out tee. Then 4 inch going up at a 45 degree angle into an elbow, then straight up for the rest.

Can't wait to try it this winter and see how well it draws.

Thanks everyone for all your help.
