BK Princess ultra: replacing entire chimney - 6 or 7" insulated chimney?

[steve19]

Hi guys,

Been a while since I've been on here. I need some advice regarding installing a new chimney.

My existing chimney is 23 years old (product no longer available). The new chimney i'm going to install is made by SuperVent (home depot carries it) and offers both 6 and 7" internal diameters.The main reason I'm asking is because on my BK princess stove, the collar that comes off the stove is slightly larger than 6", so with my exisiting chimney, I use an adapter that goes from 7" to 6". So, with my NEW chimney install, should I just stick with 6" diameter or should I consier 7" diameter?

I hope that makes sense.

Thanks!
Steve

It's best to go with whatever the ID of the stove exhaust collar is all the way up. Is this an older model Princess? How much over 6" ID is the collar?

That's weird. It's supposed to be 6". The 7" flue is a rare beast these days, I wouldn't install it.

steve, are you measuring that collar inside or outside diameter?

7" pipe is rarer and more expensive. If you chose it, be sure that all you have all the parts before starting the project.

In this case, unless the chimney height is short, or there are several 90's in the connector path, I'd use 6" chimney and put an adapter on the stove.

The Princess uses a 6" pipe.
