2 Stickers on Boiler - What Do They Mean

Hello,
I have Peerless boiler WB-3; however, there are 2 stickers attached with different boiler numbers, but the same serial number (see attached image). We're the 2nd owners so we weren't here when these stickers were changed. The 1st owners added two large additions (increasing sqft by ~1200). So, my speculation as to what these stickers are indicating is that only the burner firing rate was increased from .85 gph to 1.1 gph after the additions were finished. There were were no physical changes to the boiler and the boiler number changed only to account for the increased firing rate. Am I correct or am I missing something? Thanks!

    Your assumptions are likely correct. Nozzle size would confirm.

    There are some boilers where the number of sections dooesn't change to move up or down one model in the product line. They only thing that changes is the burner. That may be the case here. If you have (or can get) the owners manual for each of the two models on those tags, take a look at the number of sections for each.

    I'm surprised they bothered with 2 stickers. Usually it's one sticker with different firing ranges

    Thanks for the quick replies! I'll look into the nozzle and manual (although, it's an old boiler - circa 1992 - not sure what's out there). Regarding the nozzle, the numbers on the stickers assume 100 psi, correct? (BTW - it's a Beckett AFG burner).

    Well you know what they say about assuming...but it's a good guess without testing the pump pressure. It's possible they put in the smaller nozzle and raised the pump pressure. If they did, they should've noted it on the burner.
    Is this for general info, or are you having a problem?

    Thanks, Steve. This is to help me understand what we have. This could help, though, with future problems.

    The number represent the actual firing rate. A WVB-03 w/ an AFG is fired at 140 psi — a 1.10 gph firing rate at 140 psi would use a 0.90 nozzle.

    Yes, @scrook , newer specs. But the older OEM spec guides have it at 100psi.

    Thanks to all for the responses - very helpful and really appreciated! Regarding 'scrook' comment - if I'm understanding pressure vs nozzle size, according to the table below (from AFG manual), then a 0.90 nozzle with oil @ 140 psi will put out close to 1.10 gph (actually, 1.07 gph according to the table).

    Neither sticker is a true represnetation of the acuatul heat loss of the building and the size boiler needed.

    @pecmsg Now I'm curious. The reason being, I took that picture at my sister-in-laws house in NE Philly.

    If you have a .85 gph nozzle you have the lower sticker. 1.10 ghp noz the upper sticker.
