Does anyone happen to know whether one of the Lynn "Timesaver" universal cylindrical combustion chamber liners (probably their #11) will fit a Yukon Eagle ii (LWO-168)? (Of course, I would have to cut a hole for the oil burner blast tube). Or is it worthwhile to attempt a Kaowool blanket installation? Alternatively, should I forget about all that and pay the premium to get the exact replacement liner from Woodman's Parts?
I installed a replacement liner from Yukon years ago, and I remember even that required a bit of trimming of the outer diameter to get a good fit (Yukon suggested my combustion chamber itself might have become out-of-round, but it wasn't; the old liner needed to go, but I hadn't let it get so bad that the chamber warped).
My location (in the Southeast) means that there are very few HVAC guys who want to work on anything other than modern, gas furnaces or heat pumps. As much as I'd like to hire someone else to worry about the details, I don't think I'm going to find that "someone else." Those who are willing to work on the thing don't do anything beyond throwing a new nozzle at the burner, and maybe cleaning the electrodes. No pressure or vacuum gauges, no smoke test, no draft gauge, no combustion analyzer.....
