Got an older Burnham v7 with a hot water coil. That plugged up years ago, and was blocked off.
Since domestic hot water was not supplied by the Burnham, took to turning it off in Summer. Noticed the seal began leaking when it cooled down but did not seem too bad and was not noticeable once it was back in service.
Well, of course, now it is worse and for the moment have left it on to avoid, or mask, the leak.
I know there is a cover plate/gasket/bolt kit available, but it looks like a VERY iffy deal to try and move those rusted bolts. I've asked a couple pro's for ballpark and it is WAY too steep for me. Almost would make sense to rip out and go to propane.
Planning to let it cool down and give it a go. I doubt penetrating fluids of any sort will be effective as the gasket seem like it would prevent penetration of the threads at all.
First, I guess to try penetrating oils, Kroil and the like, and just try to wrench them free. If that fails, rather than go Gorilla and chance snapping the bolts, to just grind them down, remove the cover plate/ aquastat/gasket, then apply heat via oxy/acetylene to each exposed bolt in turn and try vice grips or, mig/tig a nut to each bolt and try that.
Failing all that, I guess try drill/extract? Drill/retap is, of course, the last resort.
Any experience to share?
