I found`a list of date of manufacture for furnaces and water heaters that went by the serial number on here at one time, and had it saved to my computer,but lo and behold after computer problems it was gone. Can anyone direct me to it or have a copy saved, I could sure use it again. Thanks for any help provided.

What I do is if the number doesn't match with the info I keep with my HVAC stuff I call a local vendor that sells that make. This is something I did often while working for an HVAC company. I keep a list of companies and what they sell. The counter guys are more then willing to help.

Why would you want to document a DOM when the DOI may be a year + later?
Not part of the SOP, and that is the ONLY thing that will CYA. Just a thought . . . |
