Sugar shack smoke stack question

[Pdiamond]

I went with the double wall from the base stack all the way out. I also used a boot and really like how well they seal around the pipe, but still used a collar. Me personally I would stick with double wall.

Thanks for the thoughts! I am going to look into the appliance adapter, but also look at pricing one more piece of double walled. weigh my options.

I have a 6" single wall from a woodstove and it adapts to 6" double wall with this adapter

One more thought:

To cap or not to cap? That is the question!

I had a six inch stove pipe that started out with a cap, which got knocked off because it was thought that it restricted the draft too much. I am going from a 6 to an 8” pipe, and I am getting rid of two 90 deg turns and going straight up. Will putting a cap on negate the improvements I have made? Should I be worried about inhibiting the draft with a cap? If I don’t put a cap on, it will just get covered with a bucket during the off season. If I do put a cap on, what type do you recommend?

I would definitely put a cap on it. I wouldn't want any moisture getting in there at any time. The question on whether it would restrict draft has several variables including the design of the cap and the size of your evaporator. Woodstoves have far lower throughput than an evaporator so caps intended for use with them may end up restricting the draft somewhat. I used a metalbestos cap for several years before switching to a flip style cap due to concerns about restriction and sparks. I believe it made a difference but I'm not exactly sure how much. I'm guessing that lots of people use woodstove type caps and are perfectly happy with them.

I would put a flip over cap that you can close when not boiling. Don’t use a Chinese style cap because it will restrict flow when you are boiling. You want good flow of smoke out your chimney for the best draft and fire.

I have used just a simple rain cap for years and do fine:

I ordered a fixed cap but am having it made SS. I want to do this once, and not have to redo it next year. If the draft really is an issue, I will change it to a flip cap next year. but I’m crossing my fingers that overall, considering the increase in stack diameter and loss of elbows in the chimney, it will be an improvement over last year.

Wish me luck! Thanks for all the advice!
