Finally got around to doing the summer cleaning of the WG last night. The 3 season nozzle looks like it should be replaced before next heating season. I say looks like because the refractory is still in place and not falling apart but the nozzle "holes" are enlarged.
So 2 questions....what would be the negative effects of using the nozzle where the holes are maybe 50% enlarged? ...and...has anybody replaced the 2 piece nozzle refractory? Appears to be an easy job?(dang, that's 3 questions).
I did order the replacement nozzle last year but I am hopng the WG owner that replaced the refractory type nozzle with a steel one has good results as I'm hoping to not have to do this every 3 years.
