Re: Help with Peerless PF-140, Ignition issues, Control Board swap
See how Fluke publishes the resolution. I like that, it fits in my comfort zone well. Since you have two meters with the same basic reading that does help with a sanity test a bit. Your 2015 is AC coupled conversion in AC current mode, I think I would try that just to see what it reads.
Re: Boiler oversizing factor--Siegenthaler recommends max 10% (!!)
If it's a low mass hydronic system, I'd rather have it undersized. I wanna see it run around the clock occasionally.
Re: Let me try this again, this time with a 1" supply pipe. Surely that will cause trouble!
That was the classic Iron Fireman system. @gerry gill based his system on that.

I think I’d have to try that minitube system I’ve heard about
Re: System 2000 hot water tank leak
Thank you, all. A small leak will not affect hot water production. @DanLI, clearly, something changed as hot water is no longer working like it did prior. As there are several things to check out, our territory manager, John Hachmann, reached out to the service manager at Marran and he will contact you Monday. Please PM me with your contact info to move forward.
Best,

Re: Recommendation for highly reliable natural gas water heater?...
And yet I changed mine at 5 years or so it still looked plenty thick and my tank still failed at 9 years. Hopefully me dropping my pressure from 90 to 60 will make a difference.

Re: Navien condensing boiler settings troubles
@bjohnhy Thanks for the helpful hints here, as they help confirm that I'm on the right track dealing with this issue. Seems to be just a matter of dialing things in from here, which will take some time, naturally. I am unlikely to upgrade the values of the current insulation, unless I go with rigid foam exterior insulation and vinyl siding over the brick. Time will tell. For now, I have further lowered the operating temps to a minimum of 25 degrees C and a maximum of 68 degrees C. So far, the heating is very even and smooth, completely unlike the characteristics of my previous boilers. Woohoo!
Re: Something Just Doesn't sound right about this
I’m not sure why you’re trying to remove that plug, but I would get back to where you can remove the entire fitting if necessary.
And I’ve seen the handle of a 5’ Rigid pipe wrench bend from four men with a cheater pipe on it, but I’ve never seen a Rigid jaw break. You get what you pay for and that’s why quality contractors buy quality tools, not Chinese junk.

Re: Single Riser BUT no equilizer?! one Pipe Steam: gravity return
Sounds like the boiler needs to be replaced or the BIG gamble of regasketing it which might be a waiste of time once you get it apart. Your noted questions I suspect you already know the answers to since you have the manual on the book. You just want a bunch of people to confirm your findings to make the other installer look bad? I would open up the LWCO and look for mud for my own liability reasons and if I found some in there I wouldnt run it until rectified. You can blow it down all you want but if 100 steam guys are brought into court because a LWCO failed due to sludge then they and the jury are going to blame you, suggesting that your not telling the truth about blowing it down. Ive seen regularly blown down LWCO's get sludge in them.
Re: Additional Low Water Cutoff
Just to add a result-oriented insight to Dan's article and comment from the esteemed Mad Dog 2 :
Significantly reduced the number of explosions
Did Boilers have less explosions after the invention of the hartford loop
The invention of the Hartford Loop in 1919 significantly reduced the number of explosions and cracked boilers in the steam boiler industry. This safety feature allowed condensate to re-enter the boiler but prevented complete loss of steam boiler water should a leak develop elsewhere in the condensate return line. The Hartford Loop was mandated by the Hartford Steam Boiler Insurance Company to ensure boiler safety and prevent catastrophic failure associated with a dry-fire scenario. The Loop's design helped maintain pressure balance between steam feed to radiators and return feed of condensation to the boiler, thus reducing the risk of boiler instability and explosion.

P.S. I may as well add Ben Franklin's so called "lighting rods" that he chose not to patent were installed ubiquitously throughout European cities and reduced frequency of fires caused by lighting that had proliferated prior to the invention
