dtontarski Posted April 19, 2006 Report Share Posted April 19, 2006 Can anyone help me decipher the manufacturing dates of Dunkirk Boilers? I ran across this one yesterday: Model Number: PWX-5VNT2 Serial Number: 500100433 Thanks. Dave Tontarski Link to comment Share on other sites More sharing options...
hausdok Posted April 19, 2006 Report Share Posted April 19, 2006 Hi Dave, Dunkirk uses the first four digits of the serial number, and it's the week followed by the year, so that one was manufactured the 50th week of 2001.

hausdok Posted April 19, 2006 Report Share Posted April 19, 2006 Hi All, A couple of months ago, after I put together that serial number decoder for water heaters, a few of you asked for something like that for boilers. In response, I asked folks to send me information about how to date various boilers, so I could compile same. So far, almost nothing, so I'm going to try another tactic - you guys give me the names of the boilers and I'll track down the manufacturers and try to find out how to date them myself. I'll start the list and you guys add to it. Okay? Peerless Dunkirk Pemco Buderus Weil-McLain Burnham Okay, I"m not in boiler country, I've exhausted the boiler brands that I've encountered, you guys add to this list. Thanks. ONE TEAM - ONE FIGHT!!!

Bill Kibbel Posted April 19, 2006 Report Share Posted April 19, 2006 "...are Crown & Utica the "same" thing?" Not that I'm aware of. Crown is manufactured in Phila, PA. I've been to their plant. There recent boilers are red & black. Utica is, well, I guess, manufactured in Utica, NY. Their products are always blue. Link to comment Share on other sites More sharing options...

kurt Posted April 20, 2006 Report Share Posted April 20, 2006 If you have a Viessman boiler in the US, it' most likely brand new. They didn't start getting into this market until the last couple years. They are the coolest though; the technology on those babies is thoughtful.

Kyle Kubs Posted May 19, 2007 Report Share Posted May 19, 2007 Mike, Did anything ever come of this? You know, with all your spare time helping us schleps figure out which way is up... If this is something your still working on; Smith Boilers The serial # will start with a letter followed by 3-5 Numbers. The first two numbers following the letter are the year of Manufacture. Smith started in 1853 Pensotti - Italian Made The Date is cast into the front of the heat exchanger. On the back section there will be a code that will read 15.11.96 or 15.11.1996 Depending on when the boiler was made it will also have the code on the front leg area or just below the cleanout cover. That number stands for November 15, 1996. (there is a removable plate on the jacket) Weil-Mclain you have to call them and ask for the tech dept - Give them the CP # on the data plate or sticker. (219)879-6561 Utica See the attached .jpg file -Ok it won't load. - Email me if you need it Peerless The last four digits of the Serial are the MMYY General Electric (Old) American Standard Link to comment Share on other sites More sharing options...

hausdok Posted May 19, 2007 Report Share Posted May 19, 2007 To load a .jpg photo, resize it to less than 100 Kb and then rename it without any symbols in the name or spaces. In other words kyles house(downtown) needs to be KylesHouseDowntown or Kyles_House_Downtown or something similar. Then it will load. However, if you are using Firefox or Netscape, you may need to upload it to the upload window and then cut and paste the URL to the photo into your post. I'd still like to do this, but I didn't get a whole lot of input on it as you can see. I'll be happy to pass it off to anyone that wants to tackle it. OT - OF!!! M.

Kyle Kubs Posted May 19, 2007 Report Share Posted May 19, 2007 Ok - Lets try this again. I hadit, or at least I thought it was, within all the parameters. Opened it in photoshop and the image size shows as a lot bigger then the computer is saying it is. Does'nt make sense, but I decreased it's size a bit.

hausdok Posted May 19, 2007 Report Share Posted May 19, 2007 Thank Kyle, That's great. Now, if only all of the hundreds of folks bogarting those various cheat sheets out there were to do that we might be able to come up with a pretty comprehensive single document and put it in the downloads section for everyone to use. Oh, by the way, I've got to get around to updating the water heater serial number decoder, because AO Smith Water Heaters has gobbled up State, Reliance, Maytag, American and GSW since I first published that. (Grrrr, leave it to some kajillion dollar corporation to make more work for me.). OT - OF!!! M. Link to comment Share on other sites More sharing options...

msteger Posted December 24, 2007 Report Share Posted December 24, 2007 Here are two brands I see all of the time: Burnham No date code used in serial number. Call 1-888-432-8887 and provide serial number. They will have info of initial buyer and date of purchase. New Yorker Various systems were used. Some newer models have year stamped inside main cover. If you get stuck, call 215-855-8055. I've seen a few EFM units, but didn't know their system. Link to comment Share on other sites More sharing options...
Rob Amaral Posted December 30, 2007 Report Share Posted December 30, 2007 It's "H.B." Smith (not JB). Hydrotherm/H.B.Smith are part of a group in Westfield, MA called "Mestek". On a side note, I saw a brand-new Weil-McLain oil-fired hydronic boiler with a cracked section the other day. Never assume anything (as usual). I always use an extension mirror and get on my knees to check the visible underside areas of cast iron sectional boilers for leaks. I'll try to post the photo of the cracked boiler section.
