Okay uh: what we're gon na do today: uh we're gon na cut into the dark work and install this transaction page, which already was prefabricated from rectangular to round, and you can always buy a start. Color and install start. Color then connect this to that. However, in this case, it's a space limitation, we don't have much room.

The idea is this should go here and we're going to install our elbow here and up, and we barely have enough room to put the elbow. A ball will go directly into this transaction piece and we still have to come about inch and a half towards here to be able to meet the pipe up there. Besides that, you can always make a flanges and screw that in, but the idea is it have to be removable in the future because of the water heater that they can remove the work and remove the water heater if it needs to be removed. Uh in this particular job, we don't have room.

There is no place other place to put the furnace and we have to do it so today we're going to learn how to do that on a dark work with the slips and ducts. When you don't have a place to start color on it, this is seven by six. So in this case this tag work the connection on this side and you will lose three eighths of an inch you're not going to be able to bend that. So you have to account for that.

I'm marking that 3 8 and because we're gon na have one inch sleeve that will bend this way and another one inch there and my ductwork was seven inch wide. So i have to mark that my hole should be two inches smaller than that. So i'm gon na mark six from here this, where it's gon na be i'm gon na use my drive, because this is one it's a little bit bigger than one inch, but it works just fine. You can mark there and that's going to be our cut.

This is 16, so we need 14 inch opening you mark. Your 14. should be five by fourteen. If we did everything right and it's five okay start the hole, you can use a step bit little hole and start from there or you can use a flathead screwdriver and okay after opening it here, in this case 5 by 14.

Opening we have to cut this corner on diagonal and it has to be one inch plus between a square which is about 0.4 1.4 inches. That's gives you about inch and a half, but again, usually what i do. Three quarters of the length of my snips just works fine, and it should go in a 45 degree angle compared to any of them. Something like that.

Okay, after making this cut now it's time to make the drives and slips - and here is a cabinet - you have to first bend your drive sides then bend your slip side. The reason for that we're gon na bend this at 90 degrees and later because my clipbender is only you have certain sizes, 12. 18. 24..

It won't fit because this is a 7, but this is 14. I can slide this later. When i'm done, i will explain so the way i'm doing i'm going on my one inch side. First, going to normal one inch side.

First, i am kind of breaking it, but not bending, as you can see, i don't know, maybe 15 degrees, something like that same thing. You can do on the bottom. This one also needs do maintenance just to have this brake line. That will make my life easier in the future.
Then you switch to the 3 8 side and you go all the way around 180 degrees same thing. There you have it now. You can go to your home range side and this open. And if you look here, this is a right at the edge and when you're keeping these three eights on uh that connection side, you not loosening this connection and also air cannot leak.

You don't have to do anything on this side same thing over here. Okay, here you have to use the backlash, however left mine somewhere, you can use channel locks to do that and if you can use it, but it's possible so on this side, 90 degrees. There you have it. If it is everything right, it should become a 7 by 16 and we have exactly 16 there and exactly seven there, but we are literally, then you have to install the slips on this side and drive on this side.

So another thing to make your life easy every time you have something like this two pieces install your sleep on this piece. It will be much easier to drive in than when you have on a nice side of it so cut the sleeves another thing when you're cutting the sleeve and you need multiple pieces in the same length, don't cut all the way in you cut that just leave. Eight seven inch sixteenths of an inch on there. Then you don't bend this way.

You bend this way and you have the same size on this side now and you can do this over and over. There is cases when you have to cut ten of them same size. You don't have to use a tape measure and they are perfectly same size. If you can see another thing, when you're installing a duct work it on a short that works, it really doesn't matter on a small bag works.

It really doesn't matter, but on the longer that works, it does make a difference and with a high high static pressure, dark works. It really makes a difference. You have to understand that which way goes your airflow in this case. This is a return.

Our air will go from here into there, so this space in reality, this backward, should go into it and, depending how you're gon na install your sleep that that can be different. So if you look from the top imagine the dark work that will go on this side, you want that to be on inside. So in this case, i have to install it this way, because i said you better install on a piece that have a cut now. It's time to cut the drives for this uh with the drives again, you can buy them standard kind of already prepared, or you can cut your favorite length here.

I'm making one inch extra on each side well set later. When we connect everything, we will seal that i'm not feeling it now, because i'm gon na work around and it will get messy, usually doing a mask. It's a last thing when, before you go home and it will arrive during the night thanks for watching you.
