Thanks, I have that manual already, the H82/83 were clearly built on the same basic platform as the H81, but there are some subtle differences, just not sure how many. I cannot find the rectifier mentioned in post# 193, and the hour meter operates in 110vac, so that is one difference. Fuel filter does not have a replaceable element, so that's another difference. Solenoid that controls fuel flow to burner is in a different location, and thermostat controls are different. No tube for fireeye in burner, and don't know if it even uses same fireeye.
I've cut out a piece of plexi so I can see if light is hitting fireye, just need to drill some holes and mount it. Heading out now to open the burner chamber on one of the H82's to see if one of those fireyes will work, maybe pull the burner too. Did some looking around online last night trying to find a replacement fireye, photocell, etc, used multiple terms and found nothing that is an exact replacement for this one.
At this point I feel like I'm grasping at straws, maybe problem was not nozzle, but in opening it and cleaning it maybe I contaminated it and that is why original no longer works???? Fireeye worked before, but now its either not aligned right, or maybe its what caused the problem in the first place??? Maybe fireye is fine and the problem is the K8 relay?????
Original nozzle was 1gph 80degree (think I said 90degree in a previous post) type W (general purpose) nozzle. The one I replaced it with is .85gph 80 degree Type A, flame is nice and bright, I can see light from viewing window bouncing off the milling machine, so why is fireye not seeing it??? Could nozzle be the problem???
