With a direct vent, I would think a double wall would work fine, you just have to seal the joints on the inside, since it is pressurized. Depending on how far you have to go outside and your budget.

Black you will be replacing probably every few years due to corrosion. Stainless will last much longer, but you really only need the stainless on the inside (Kinda like the pellet vent pipes). Stainless will be probably 3-4x the cost of the standard black pipe...

I'd use stainless single wall wherever the vent pipe is exposed to the room air.. you will get some addtional heat from the pipe.. no reason to send the heat outdoors... Once you go through any part of the structure of the house, [with the exception of a hole in concrete] you must use some form or insulated or double wall pipe.

I have a few questions on the same subject..My Alaska Channing III direct vent stove came with a stainless steel flex pipe but I have reservations about it's safety. Has anyone here used a flex pipe straight out of the back of their stove? Will this pipe collect more of fly ash? / Do they leak?

I have used the SS flex on my pellet/corn stove for a couple of years with no issues on ash collection because I belive with such a short pipe not much ash settles out. However I don't know how about coal ash. If your system is a direct vent and not a power vent you will need to seal all joints in the system as they will be under pressure.

Its been about 3 days that we are looking for the pipes for the direct vent system.
Theres already a hole in the wood part of my foundation where a dryer vent once went.
When we bought the stove, the man litterally just unhooked all pipes and gave me the direct vent and had a 6 inch duct put in it by Keystoker.
First off, I thought I could just go to Lowes and buy the stainless pipes that I needed.. DUH!
Now, Ive been on the phone for 3 days with a .com company thats advertised here and Im getting kind of sketchy as to if he's going to deliver or not.
Is there a number that I could reach Keystoker at?
Is there a secret place that sells the pipe I need? (whether it be in the NE Pa. area or somewhere UPS delivers)
AND
It's my understnading that I only need to go 1 foot out of the house when using a direct vent?
(I just got new vinyl siding on the house and don't want to ruin it...plus the Co2 levels...)
I did fax the directions to the .com company and he has called back twice trying to understand what I need. Im just wondering if theres a specific Keystoker kit??? Or because Im going thru the wood do I need to buy each piece seperatly?
Thinking too much.
Thanks
Boxer
