In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I'm trying to determine if the F6 head that is currently on my New Yorker FR-122 boiler (circa 1989) is still OK now that it's been downfired to the same as an FR-98 (1.00 nozzle down to 0.85). This thing seems way oversized; even with the 0.85 nozzle it's been running about 6-7 minutes at a time 4 times an hour even with the outdoor temp10 degrees below design temp for this area (approx. 10 degree F). The oil service company installed the nozzle at the annual cleaning after I mentioned how the boiler seemed to be short cycling. But based on info I've read in this forum the stock F6 head may be incorrect for the 0.85 nozzle. I have noticed soot dust around the stack damper and on top of the boiler and the damper slams shut during most start ups (which it didn't do before). So, should I be concerned about this? I'd like to have this thing run fine tuned rather than just in the ball park. Thanks for your time.
