Pellet Stove Venting

[Lemms]

Does anyone know if “pellet vent” and “B vent” are the same type of exhaust pipe?
My brother does heating & cooling and never heard of “pellet vent”. He said that we should be able to just use “B vent” for the exhaust on our new pellet stove (Quadra-Fire Mt. Vernon). Any ideas?
Also, I am placing the stove against the exterior wall on the front of our house (facing the road). So, we were going to vent it straight out the front extior wall. There is brick on the outside of this wall (about 50" up anyway). This seems to be the easiest way to vent the stove. Does anyone recommend venting it differently?
Not really excited about cutting a hole out thru our brick, but I am excited to get the stove hooked up and running...

Answered you in your other post, Lemms.

Yep... Thanks...
I just thought that I would start a new thread with these questions, seeing as though they were off of the original subject a bit.
Do you have any recommendatiosn regarding the second part of the post, regarding venting through our brick? Should I face it that it is our best option?

Rather than going through the brick it may be easier to go up from the stove and then out and as far as outside air(from the other thread) there have been a few posts here where salesmen had said it was not necessary but people have found out later that they need it. It's easier to install it now and plug outside air if not needed rather than add it later. How old is the house, windows etc.

From your description your proposed install is common. Venting up then out would probably be easier in relation to cutting through the wall but most likely wouldn't look as nice, considering its the front of your house. The only other advantage to venting up and out is that if you were to have a power outage, where as the combustion (exhaust) blower would stop running, there would be a little natural draft to help get the remaining smoke out of the stove instead of into the house.

I disagree with the blanket statement of "never direct venting" or horizontal vent a pellet stove.

Over the years I have seen very few instances where soot was forming on the house. The cases that I have seen where always due to poor planning. Usually, it was a situation where the terminated behind a fence or bush or close to a inside corner of a house. In other words, a place where there was very little natural air movement.

The picture on that link is definetly a "never do" but that is because the right parts are not being used. The reason being that the cap on that horizontal run is the cap that is designed for a vertical run. The exhaust would travel down the pipe and smack into the solid (what would normally be) top of the cap, basically defecting back toward the house. That cap is installed sideways. Most likely, if the correct cap was on that installation there would be no soot. Another consideration before installation should have been how well does air travel under that roofed in area?
.

Check out the pictures that Craig posted of the cap on the wiki pager. That's the right kind of horizontal cap.

Yes that was the wrong cap
but we have RE-Installed 50 or so over the years that had the proper cap and the walls were still black and or Smoke backing into the house.
WHEN the power goes out smoke WILL back into the house on ALL directvent installations.
so we will NOT direct vent our stoves. I dont care if it cost me a sale I can sleep better.

If we cant Go all the way with pipe I like at least 5" of Vertical for draft with 90 at the top then a 12" and a Horizontal cap to get it away from the house.
