Using double-wall stovepipe

[Ashful]

So, I'm looking to switch one or both of my stoves (Ashford 30 and 30.1) over to double-wall stovepipe. I've only ever worked with single wall, so I'm not clear on what adaptors are required at stove and liner, to go double-wall.

On both stoves, I'm using a 6" smoothwall flex blanket-wrapped liner with the following adaptor:

1. First stove, top vent with straight shot up to liner, I'm using a single telescoping single-wall section. Should switch to double-wall to improve draft on this very short chimney.

2. Second stove, need double wall due to CTC issue. Also top vent up to liner, but with a 9" jog, likely to be accomplished with a pair of 45-degree elbows.

You will use the appliance adaptor at the top of the double wall pipe, you will use a stove top adaptor on the stoves flue collar. You'll likely need to crimp the appliance adaptor.

Would you use something like this at the stove?

That's the part! Although that's a dura-vent part, not sure he's using dura-vent. I prefer it, that's what I have on my Ashford. Their adaptor fits very nice, the Ameri-Vent/Super-Vent is very sloppy! I don't recommend it for a BK, it's so sloppy I am afraid of smoke leakage at the connection.

That's what I used too. Check the stove's collar welds for blobs of weld or anything else out of round that would interfere with a good mating of tapers. I had to grind out a big blob of weld.

Okay. So keep appliance adaptor I have, and buy that adaptor for stove? The appliance adapters are already tapered or crimped (can't remember which) to fit inside 6" pipe.

Was going to use Rockford Chimney, since I have some stuff to return for credit there, unless anyone has a reason I shouldn't. Not sure what brand they carry, but the single wall I've always bought from them is the nicest I've handled.
