AO Smith Serial number longer than 10 digits

Recommended Posts

I have a 81 gal 154,000 btu A O Smith hot water heater I need help finding the age of. It looks like it was recently installed (2years) but, I used Mike trusty age chart and this serial number is longer than the charts coding. Serial number MMO1-1353893-110. Does anyone have a new date formula?

Thanks for the help.

While no files are being looked at, and really have no literature to back up anything, just a quick glance of the SN, I thought 01 as well.

81 gallon - 154,000 Btu? That's a commercial unit. I'd suggest giving A.O. Smith's commercial division a call in the a.m. and ask someone there to email you a copy of whatever document they have that explains how to decode the serial numbers on their commercial units and then we can add it to the chart.

IF I remember to do so, I'll call 'em too.

ONE TEAM - ONE FIGHT!!!

Did you check the date on the TPR, the gas valve, and the gas connector?
