# Apparently 8" diam. clay flue pipe is not available anymore (the factory out here is not making it according to my brickyard)

I think your vendor is lying to you. 8" square flue tile is a standard construction item. You could probably special order it from the home depot contractor desk if none of your local brickyards handle it (?). Around here, they are stacked up high.

Re: Napa WFO dome & hearth build questions

...1st question: since you can't get the 8" round, do you mean getting a 12 or 14 oval (rounded rectangle) and cutting it diagonally in half and re-mortaring together? If so, there's at least 3-4 that I've seed do that successfully (check out mfiore Mike, he did that)....

Yes that is what I meant and I think I am going to try it for the transition.

Just a heads up: your brick work and mortar look really nice. Good craftsmanship and very clean. But do try to offset those vertical brick joints on each row. Your pic (3rd one back) has the 1st brick off the left entry arch-wall lining up for 3 rows. I know it's bound to happen where you cant help it, but try to mix it up...
Cheers, Dino

Yeah, I forget about it at the beginning about the joints lining up, I get most of the rest in a running bond pattern, but the hemi-sphere and angles seem to mess with my joints after I get going in a rhythm, then it is usually too late! As I sure aren't going to take bricks out that do fit!!!

Just the got to the first into/over the arch brick today and it pretty much knocked my ***, but I finally got the one side.

Wow. Great looking stone and brick work.

Re: Napa WFO dome & hearth build questions

Hey Eric,
The big stones and rocks are really great. It's going to look so good. Regarding your questions, I have some thoughts to some:

3rd question: Offsetting the flue is no problem, but it's ALWAYS better to have a larger throat transition just to be safe.

2nd question: I'm not sure. Just can't picture it.

I like your entry arch, turned out very nice.

Oh, the random stones thrown in through all the brick work is really nice. Can't wait to see it all done.

Vent Questions: Napa WFO dome & hearth build questions



I have my dome started, my first arch completed and have some questions regarding the vent transition.

1. Apparently 8" diam. clay flue pipe is not available anymore (the factory out here is not making it according to my brickyard), Should I cut down a oval?
2. I want to make my transition out of a standard fire brick laying flat. Should I cut 4" out of the middle of the arch bricks about 12 1/2" long to approximate the cross sectional area of a 8" diameter flue pipe?
3. Will offsetting the centerline of my flue effect the draw? Would I need to increase the throat dimension of the flue transition?

Thanks for any help, Eric

Re: Napa WFO dome & hearth build questions

I am ready to start my dome (finally!) and have decided to:

1. Cut the floor bricks to fit "Inside" the dome
2. Use half bricks for the soldier course

I have mocked up the second ring (first after the soldier course) and it seems that I just need to use half bricks with no real taper to them:

1. Is this correct?
2. Do any of the rings require tapers?
3. Is each course/ring only have one cut on the last brick as a keystone?

Help!!!! Eric.

Re: Napa WFO dome & hearth build questions

You can make "A" = "B". Since you have a beveled opening, you don't need a jamb or reveal on the sides. Simply bevel the door at the same angle and it will fit snugly. You may want a small jamb at the top edge.

Re: Napa WFO dome & hearth build questions

Thanks Dino for the drawing. I am just starting on my oven here in Grand Rapids, MI and was searching for a good floorplan drawing to set the openings. I like the flared opening and plan to replecate this on my oven as well.

Re: Napa WFO dome & hearth build questions

Dino,

Thanks, I have decided to go with a opening of 20" a hearth opening setback of 21.5" and a hearth front of 22.5" for a small hearth taper.


Is the dome opening arch installed vertical? I am assuming so.

Could someone point me to some good pics of the dome to hearth opening transitions and how to handle the bricks?

Thanks again for all the help, Eric.
