We have 3 inserts now, and i feel i need to get some outside air kits installed. I noticed this morning the heating vent in our bathroom was flowing cold air while the pellet stove was on so I think I'm pulling in outside air into the house making drafts. How do you run outside air kits in a chimney with no exterior wall? One stove is in the basement which means if I go all the way out I needa 25' outside air kit! Can I just run the OAK above my block off plate?

uou want your oak pulling fresh air not dirty old air out of your chimney. With 3 inserts you re pulling alot more than you realize through cracks and such in the house and also run the risk of having to much carbon monoxide in the house.

Masonary chimney’s? Liners in the chimney’s? Flex liners go to the top of ea. Chimney? What does the manual say about adding OAK?
Masonary, yes with flex liners to the top. The accentra was installed from the fireplace store, no OAK from what I can tell since the top is capped. OAK is talked about, the second stove in a greenfire and OAK is recommended. The third stove suggests an OAK but the run shouldn't be over 20 feet, well that's hard since it's in the basement.

What he said! Or run the duravent one piece pipe that the outer ring actually pulls down fresh air.
That would work but my understanding is that he already has 2 very expensive stainless liners running up the chimnies.
So I need to run another pipe all the way down for the oak is what I'm seeing.

I found 25' of OAK for harmon stoves on ebay. Going out the back wall would either take air from my dining room or laundry room for 2 of them!

I do not comprehend what you are saying. Are you terminating inside a room? Please articulate your statements, you do not want to pull air from inside the structure!

I think the user meant that if he did go through the back of the chimney the termination would be inside another room.
In regards to the original question, the best route would be up the chimney with another pipe beside the existing liner. There are caps made for this. I would never run appliances like these without outside air due to wasted heat as well as a safety hazard especially if there is draft vented gas appliances in the house.
Does the fireplace have a cleanout? One of mine has a cleanout door that leads to another door on the exterior brick surface. I ran a short OAK out the cleanout out the exterior cleanout door, after fabbing sheetmetal plates to block off air intrusion thru the open cleanout doors.
