Re: 1.414 Math, 45 degree offsets, a quick tutorial




You can fake it with small pipe or PVC. Try holding 4" Victualic fittings or larger and trying to measure it uo yourself.
The indoor chiller I piped by myself on site with no help it was a replacement. 8" chilled water with the 45 deg rolling offset. The condenser water was 4" or5" can't remember. Yeah it took me a while.
The outdoor chiller I went to the job and measured everything once the chiller was set and had all the pipe cut and grooved at the shop. I was not going to lug all the equipment needed to groove that stuff and then have to set it up and lug it back. Probably took me a day to measure it and draw it so the shop could fab it. Then I pulled the pieces up through the roof hatch myself.
Guess that is why I am all busted up and can't work anymore.

Each person told their history and location.

Geez. The more I learn, the more I dislike the previous owner.
Re: Rust on Brand New Burnham Boiler
Terrifying as the homeowner. Should I get it on “file” with Burnham somehow or they just going to toss the photos if I send them their way?

It's amazing how dangerous things are once they're regulated.

Was that with punch cards or patch cables?Jamie Hall said:Before someone wonders... I do also have a couple of university degrees... and served my country many years ago... but i got my PE license the old fashioned hard way, starting as a labourer... Not much heavy equipment, except cranes, I haven't operated at one time or another. Building inspector... some surveying... some computer programing... but that's all behind me now.

Re: Completely brand-new setup and we continue to have issues.
Nothing looks wrong or too cumbersome to service. It's concerning that the burner was changed. Why? Either way it sounds like the thing needs to be tuned, by someone with a digital analyser and who knows how to use it. All is not lost you'll be happy when it's set up correctly.Really? How easy is it to get that flue connector (the smoke pipe from the boiler to the chimney base) off to inspect the base of the chimney? or is that not included in what you call maintenance? And the electric switch has a conduit next to the DHW cold and hot feeds that drop down very close to the top of the boiler jacket that needs to be removed to inspect the flue passages in the top of the boiler. Or maybe that is not included in your maintenance service. It's in the manual for annual inspections.
