总承包商凯文和贝琪·卡尔曼向鲍勃汇报了目前的进展。泥瓦匠们正在努力建造壁炉，一个特殊的高级粘土拉姆福德火盒。在外面，鲍勃和杰夫·戴维斯(来自Chadsworth Columns)监督着沿着门廊安装新柱子。回到室内，拉姆福德的壁炉正在做最后的润色工作。
- 第一部分:建造一个拉姆福德壁炉
- 第二部分:回顾房屋的框架
- 第3部分:固定承重柱
- 第四部分:安装壁炉喉道和烟道
-
石匠为拉姆福德壁炉安装喉道和烟道。喉道可以防止加热的室内空气通过烟道流失。(一旦壁炉建造完成，喉道将不再可见)。铸铁挡板和烟室标志着从壁炉到烟道的过渡。
鲍勃·维拉:吉姆，这种折光灰浆凝结得很快吗?它和普通灰浆有什么不同的特性吗?吉姆:它的工作原理和普通的臼差不多。它确实凝固得快一些，但它是高温砂浆。鲍勃:现在我们有少量需要用铲子铲到实际预制喉道安装区域的顶部，对吗?吉姆:是的。设置我们之前说过的弯曲的排，保持气流层流，使热量较少的房间空气通过烟囱上升，通过层流，它允许烟雾留在后面，这样我们就可以建造一个没有它的高盒子。鲍勃:所以这是拉姆福德伯爵的两个关键元素之一，那就是它和高高的、浅的、反光的壁炉。开始了。那有多重?吉姆:大概有200磅重。 Bob: These guys are strong. Jim: Yeah, they are strong. Bob: The throat itself will not be visible once the rest of the chimney comes to together, right? Jim: Exactly right. The throat is right at the top of the opening, and they'll lay block across it, and it'll be a smooth, finished opening, no lower than that, but the throat will be hidden behind the block. Bob: Yeah, it's a shame because it has a pretty shape. It almost looks like an oriental pagoda. Jim: You can always get in the fireplace and look at it. [background noise] Bob: Is it proper to use the same refractive mortar even on the back side of it, once you've gotten away from the firebox itself? Jim: It's not necessary to back it up with refractive mortar. Everywhere there's a lining, like the flues and the smoke chamber pieces should be put together with refractive mortar because it's close to the flue surfaces. Behind it, it doesn't need to be refractive. Bob: So, the cast iron damper goes into place. [background noise] Bob: Then, Jim, the clay piece that you've got over there is one of two components, right? Jim: This is half of a smoke chamber. The other half goes the other way, but when we put this in here, then that will make the transition from the throat area where the damper is to the flue sides. Bob: And the flue then begins to go up? Good.
