One of the worst-maintained oil-fired boilers we've seen
came out this week. Utica OU-500 steamer with Wayne MH burner. Owners were tired of the oil company not being able to get rid of the oil smell and high fuel bills.
Well, folks, it's not rocket science. First, you have to actually vacuum the firebox instead of leaving it full of soot and sulfur. Then, you have to actually brush out the flueways. After that, you actually have to bolt the flueway cleanout covers down instead of just sticking cement around them. Finally, you have to tune the burner with a digital combustion analyzer.
There was a nice clean service tag with several recent "PMI" visits noted, all by different techs.
The 2-inch colliding header didn't help either. This boiler has 2-1/2" tappings, and it wouldn't have been any harder to build a proper 2-1/2" header.
Oh, and we don't need no stinkin' main vents! Someone really smoked those plugs in, we had to get them out with Kroil and an impact wrench.
If you are a home or building owner who has an oil-fired boiler, this is definitely NOT what it should look like inside. If it does, you have the wrong people servicing it.
If you are an oil company and this is how you "maintain" your customers' equipment, your company will fail. Guaranteed.
