OK.. so I should have my hearth ID taken away.
About half way thru chiseling out (used an air hammer) my old nozzles.. I realized I should be taking pics.
I didn't. Not a one.
The job was a BIT bigger than I thought. But it was mostly just in my head. The nozzle didn't just "pop" up and out like I thought. They are cemented in more or less in the 60 and the 80.
So.. I pretty much had to re pour the whole center. When I had it all cleaned up ready to pour, you could see the two tubes which carry the gas to the nozzle. You need to make a form of some sort to make the connection between the nozzle and the tube. I ended up using thick wall vinyl tubing. I had some old scraps from my biodiesel lab. It wasn't perfect.. the fit was tight inside the tube, but due to tightness around the edges, all I did was put them flush up against the nozzle, not THRU so I could pull them out after the refractory hardened.
I got a good hot fire going.. and let the vinyl burn out. Worked good. Or at least I should say.. it's working good now.
The new nozzles for sure put out a better flame. Whole bottom of firebox is FULL of a huge flame when it's gassing. Nozzle is a bit more high tech in construction and has 'ported' holes instead of just what looks like holes drilled thru refractory.
No pics.. sorry!
