Refractory fix?
« on: October 30, 2017, 11:36:21 AM »

I've been burning my Optimizer 250 for 5 years and I'm getting some degradation of the base refractory around the nozzle insert.  Has anyone done repairs to the stock refractory?  What would you use to repair this?

The base refractory is beginning to crack around the nozzle.  I have cracks beginning to form from the nozzle edge running perpendicular towards the side of the unit large enough to stick a putty knife into.  The nozzle inserts are beginning to sink down so it's sitting 3/8" below the refractory.  Anyone else experiencing this?

Anyway you can drive something for a wedge on both ends to close the gap?
