Weil-McLain EGH Gas Boiler question

[Demetrios3]

I am trying to size an existing weil-mclain egh gas boiler but I am having trouble determining it's BTU capacity. The UL plate is missing and I can't find the model number anywhere else. All I know is it has 14 heat exchangers.

Can anyone tell me it's capacity?

Hard to guess outside of revin' er up and clockin the meter

Probably an EGH85.

About 350,000BTU input.

What size does the house need, is the question.

Could be a 75, at 300,000

Parts list shows the 85 with 13 plus 1 pilot bracketed for a total of 14,
