Tarm Solo 30 nozzle replacement

[Rory]

I kind of dreaded tackling this, as things I've never done before have a way of turning out to be much more difficult than I typically anticipate. This time, though, I was pleasantly surprised. The process was quite painless and only extended because I saw a crack in the tunnel I replaced two years ago, and this was the opportune time to run to a hardware store for some furnace cement and repair it in hopes of extending its life. I fired up my Tarm in January of '09, and, as you can see, there wasn't much left of my nozzle at this point. While it would still gasify, the flame was usually yellow and not the blue and white I remember. The new one is in and I'm giving the furnace cement a few hours to dry before I fire it up. The instructions that came with the nozzle actually said to give it 10 or 12 hours after installation before firing. I don't understand that, as there wasn't any adhesives involved or anything. Perhaps they are trying to cover guys that bring the refractory in from the cold to install it, I don't know. At any rate, if you are due for this, it's not a bad job, but you might consider having some furnace cement on hand in case you spot something that could use it while
you're in there.



It was due

So nice and clean.



The prepped firebox.



Hopefully, good for another 5 or 6 years.



The remains.

Rory, I too have a tarm it's a 40 that I installed in '09. My nozzle looks pretty much liked yours did. Was it difficult to remove/replace? I thought that it was installed with some sort of adhesive, and was worried I'd mess up a whole bunch of other refractory trying to remove it.

The 10 or 12 hour wait in the instructions certainly seems to imply there's an adhesive, but it didn't come with the kit and it wasn't mentioned, so I put everything in dry. It's generating a nice, blue, classic "moustache" right now, so it seems to be fine. If I find out differently, I suppose I'll have to redo it, but I put the gaskets in dry. It was much easier than I expected.
