BK King vent set up-double wall pipe etc.

[mwhitnee]

I have a new BK King parlor which I bought in July and has not been fired yet. They had a wood stove exchange program and I was able to trade in my wood stove in the barn for a $1000 rebate and got the stove installed for 3K which I think was an OK price. Then sold the Defiant 1A I had.

Anyway, they used single wall stove pipe which was no surprise. I know my set up is not ideal with the short vertical stack but I cannot change it. I am also not in the market for an insulated chimney liner as I spent 6K on the stove and having 9 trees cut down in the yard this year. The liner is 7" X 11" terra cotta liner in good shape and I will be sweeping it soon.

So I have a few questions and was hoping you fine folk could help.

1) The pipe going into the chimney is iron (gonna paint that). The installer put a pipe inside this, does this need to be double-walled as well? I wouldn't think so as the masonry pipe is iron, but I also don't know how it would connect to single wall pipe.

2) I know I should use two 45 degree pipes instead of a 90, but why?

3) Looks like I am going to need an adjustable vertical pipe due to measurements?

If you have any suggestions on where to buy the pipe on line or any other advice it is welcome.

Well an 8 inch pipe has a cross area of about 50inches squared your liner 77 inches squared. Not sure if your draft will be good I'm sure others have more experience. The king likes an 8 inch pipe right? Man I'm glad I went with the Progress I wanted the heat of the King, but I couldn't justify spending that much for something so ugly. Nice hearth

Wow... I bought my Ashfords for $2900/ea, and my place only charged $100/ea to deliver and wheel them onto the hearth. Full hookup would've been another $200. Glad I don't pay Massachusetts pricing!

The dual 45's are to maintain upward slope, and provide better velocity per unit pressure, versus a single 90.

8" flue. I had a defiant 1A last season with an 8" flue and had a great draft, not having to prime the flue on cold starts. In addition a tree was cut down this year that I'm sure was affecting the draft to some extent.

I agree that it's not the most beautiful thing in the world, but when it heats my whole house I'm sure I can live with it.

Yea if you have the two feet of rise and it worked before I think your good if not you could drop the liner in next year or whenever.

I got free delivery but getting it off my trailer now that was interesting. My buddy was able to move the 700lb beast with a hand truck basically by himself down a ramp. Not something I will ever forget.

 

[mwhitnee]

Yeah I had to have them deliver/install it due to the program I used. It looked... challenging.

Your BK will run with flue temps that are probably half of what you saw with the Defiant. Or less. You'll need all the help you can get with draft.

Double wall pipe and the 45s may help, but don't be disappointed if you don't see the performance others write about here.

 

[quotejso]

So how tall is the chimney?

 

[mwhitnee]

Right around 24 feet total.

 

[mwhitnee]

Anyone care to comment on my other questions? I would like to start ordering the venting.

My gut feeling just by looking at the pic's is that you may not have enough room to install (2) 45 deg elbows, you may also no have enough length from stove collar to your wall thimble. There are pretty specific measurements (minimums) that are listed in the manual.
I run a princess parlor and like other posters have said there is definitely lower flue temps. You may have some issues with drafting (most likely during start ups) with your current setup. What I would do right now is open the bypass on the stove and lite some news paper and see what the smoke does. Draft should be less (summer time) so if the smoke gets sucked out now you may not have an issue with draft.
During the stove season you will need to keep a watchful eye on your chimney, I would check it every month to make sure you have no excessive build up. You really may want to consider installing an insulated line to maximize your flue temps (keep them from condensing)
Good luck

Lit newspaper went up the chimney no smoke entered the room. Draft seems fine.

I have the room to move the stove away from the back wall a few inches.

The tall outside chimney is where most of the heat loss is going to occur. Given the short length of the vertical run of single-wall. I would be tempted to just run it like it is for the first year. If you want to make it skookum go double-wall. The 90 should be ok with a good strong draft. Yes, to using a telescoping length for the vertical. Check the flue and connector after each cord of wood that is burned.

Was the whole chimney system inspected for clearances and condition? If so i would switch it our for double wall with a 90 i dont think you have room for 2 45s. single wall into the thimble. Then run it for a season and see how it does. You may be fine without a liner

Thank you will do.

Don't spend a dime. Run it as is and then if need be, you can look to spend to improve the draft.

By the way, I have a King parlor model. Not necessarily the best looking stove but while others play with their stove and reload....we can spend time with more exciting endeavors.

 

[mwhitnee]

I cleaned the chimney myself- new brush. Shone a flashlight down looked clean with no cracks. I also used creosote remover last year throughout the year.

I cleaned out the chimney door extremely well and made sure the door was tight. The chimney looks fine.

My thought at this point is to use double wall with a 90 due to possible clearance issues and possibly get a double wall pipe to go through the length of the thimble.

Like chimney cleaning...

That does not take place or a real inspection. Even seasoned pros cant see cracks well just with a light. And can you tell how much masonry you have around that clay thimble?

Yeah like doing work on the house (with beer in hand)!

 

[mwhitnee]

I am unfamiliar on how to determine how much masonry there is around the liner.

If i were to guess the terra cotta liner was installed with poured concrete around it? It looks like this although this is another chimney at the house. The liner sticks up a few inches which allowed me to put a ss cap on.

 

[mwhitnee]

Maybe I should just fire the damn thing and see what happens.

Yeah, but repair or replace that chimney crown before winter comes. You don't want water getting down in those cracks and freezing.

I have never seen a crown that covers the end of the liner, but that may be a regional thing. Here, the liner extends up past the crown 2" - 4".
