Where do I get this part for an oil furnace? Has the furnace died?

Where do I get this part for an oil furnace?

In a way, maybe I should wait and see what happens tomorrow, but I am
hoping to learn something in advance.

I just noticed or just created a hole in a sheet metal part of my oil
furnace, a small box that connects the firebox to the flue. It looks
rectangular from the front, top, and bottom, and trapezoidal from the
side**, shorter at the front than the back. It is open in the back to
connect to the firebox and has a round hole near the front in the top
to connect to the flue. (Is there a name for this part?)

The man is already scheduled and coming to clean the furnace late
tomorrow morning. Even if he leaves his shop without the part, if his
company stocks it, I can go there and get it while he is at his
earlier customers. Do they stock things like this? The Carrier oil
furnace is 20+ years old. If I give the company the furnace model
number, might they have this part in stock? Or do they make one when
they need one? Or will I have to find someone to make me one?

Is he going to insist I need a whole new furnace because this one part
is crumbling? If he said that, would he be right? I ran it for
about 20 minutes last month and it worked fine. The hole appeared
today, probably after I pushed on the metal with the shop vac tube.

**I have more exact measurements but it's roughly 5" high near the
firebox, 2.5 inches at the front, and 18 inches deep, and 14 inches
wide. Plus it has a flange around it that gets screwed to the
furnace.

A heating and AC wholesale parts house might have it. Or,
take a couple digicam photos and take the camera to your big
box hardware store. I know one small town hardware that has
a lot of heating parts and pieces.

I guess I should have thought of that. Thanks.

Do you know if I also need some sort of caulk or gasket to attach this
part to the firebox and to the flue? I can't see what's under the
flange, but there seems to have been nothing between the other, round
flange on this box and the flue.

I think it wore out earlier than it would have because the humidifier
overflowed on a few occasions and the top of this got wet.

I told them the problem, and said I was trying to avoid an added call
by their tech to see what is wrong, and they've postponed the
cleaning.

When there is fire in the chamber, do the exhaust gasses flow thru
this pipe on the way to the chimney? If so, you are risking a fire or
air poisoning if you don't replace this part. But, if this metal is
so thin, what about the entire fire box?????

You're right. I absolutely have to replace the part. The oil company
guy said that Carrier doesn't have it anymore, so I'm going to call
local heating supply stores.

Any other ideas where to look?

It's called the Flue Collector, and connects the firebox to the flue.

It's not sheet metal. It's steel. If I can't buy one, I was thinking
that I could get a welder to weld a new layer of steel over the part
that is thin. It's open at one end, and I think the other 4 sides
are good.

They've removed identical furnaces from here when my townhouse
neighbors replace them, but I guess they are crushed and recycled, and
don't sit in junk yards.

> But, if this metal is

Good question. I think, and the repair manager at my oil company
agreed, that the rust here was accelerated a lot because the
humidifier overflowed and dripped water on the top of this part.

Doesn't the furnace cleaning guy warn the customer when the firebox is
leaking? I asked last time and he said it was good.

And I've been using a CO detector and it hasn't gone off, and last
winter I put cloves in the firebox but didnt' smell anything where the
heat came out of the vents.

Thanks.
