Shows up as a “pool heater”. Sure you’re looking at the furnace?

yes Jim that is it a poolheater ?

The Teledyne information I have says the second and third digits are the year, so 1950. Hmmmmmmmmmmmmmmm.

You might have a unit that was built in Canada using Canadian moderl and serial numbers, which I don’t have.
