DuraLiner and DVL to Progress Hybrid

[IrishCowboy]

I asked about this at the end of my chimney thread here https://www.hearth.com/talk/threads/old-brick-chimney-line-it-fix-it-abandon-it.153506/, but I didn't get any traction, so I thought I'd make a separate thread out of it. We're putting a Progress Hybrid in our dining room. Given the size of the flue and the need to insulate the liner, we're planning to use (oval 6 inch equivalent) rigid pre-insulated DuraLiner. In the room, we're thinking of going with DVL for reduced clearance without the need for a pipe shield. I've attached a couple of sketches showing the setup in the dining room as I see it.

I've assembled a parts list of what I think we need, both for the in-room hookup and for the chimney. I'd appreciate if anyone can let me know if I've accounted for everything. I also have a few questions for the experts:

1.) From looking at the drawings of the DuraLiner wall pass-through (thimble), it looks like it protrudes 12" into the room before I even attach the 90-degree elbow. Is this right? Is there any way to reduce this? Is it possible to use a different brand of wall pass-through and still mate correctly with DuraLiner and DVL? With the DVL, I think I can get both A (with a rear heat shield) and B in the side-view drawing below 12", and I'd like to do so, if possible.

2.) Is anything required at the top besides the liner cap extender kit I have listed?

3.) Can anyone think of a better way to make the 5-6" offset work out more cleanly than what I have depicted in the drawing? I was thinking of having the 90 elbow turned counterclockwise 45 degrees from down to meet up with the 45 elbow. I can afford a little left or right play to make that happen without a short connector piece between them, I think.Is any sort of coupler required to make a 45 mate directly to a 90?

4.) What are your opinions on getting a damper in the stove adapter? Good idea or bad? I think I'll have at least 20' of liner in the chimney.

I think that's it. Here's the prospective parts list and where I found them:

DVL:
1 x 6DVL-ADWD DVL Adapter/Damper Section - 8679
OR 6DVL-AD DVL Adapter Section - No Damper - 8680
1 x 6DVL-46TA DVL Telescoping length 29-48" - 8646

1 x 6DVL-E90 DVL Double-Wall Black 90 Degree Elbow - 8690

DuraLiner:
1 x 6DLR-WPT DuraLiner Wall Pass Through - 4644
1 x 6DLR-OTRB DuraLiner Oval Tee With Round Branch With Cap - 4667-O
1 x Insulation (if necessary) for the Tee
5 x 6DLR-48O DuraLiner Oval Rigid Pipe 48" - 4648-OP
1 x 6DLR-24O (If necessary) DuraLiner Oval Rigid Pipe 24" - 4624-OP
1 x 6DLR-KXC20 DuraLiner Extend-A-Cap Kit (oval 13 x 20) - 4688-O

Perhaps a PM to BHollar, he's the one of the resident chimney doctors on this forum, fyi I like your attention to detail on the drawings, showing the loading handle on the stove

I would call DuraVent support and ask about connecting the DVL to the liner to verify correct adapter.

 

[bholler]

I would be glad to help but I don't work with simpson products so i cant give you much input on the duraliner I am sorry. I would do what begreen said and contact them for clarification

 

[IrishCowboy]

Thanks for the fast response, guys. I'll definitely call the manufacturer or a distributor to ask about the connections and so forth. Any thoughts on the last 2 questions?

Does anyone see a problem with a 45 into a 90 and through the wall? I'll have 20+ feet of liner, so I think the draft should be alright.

Also, what are your feelings on a pipe damper with the Progress and that much liner? I suppose I could always have it in there but not use it.

 

[fire_man]

I'd be surprised if you needed a damper with a 20 foot liner w/ the Progress. The stove is easy to control and 20' is not excessive anyway.

 

[begreen]

Sounds like it should work ok. Agreed no need for a damper.

What appeals to us about the DuraLiner is the fact that it's preinsulated and has favorable dimensions for our existing clay liner. But I'm not married to the idea of using exactly this product if another manufacturer makes something equivalent for less money or with higher quality, etc.
