Hi everybody,

I am buying a house and was wondering if anybody could tell me how old this furnace is based on the serial/model number?

Serial #: EK 1006
Model #: GZ-LEV-110

Thank you!

Hi Bryan,

Appears this model was manufactured between 1973 and 1977
Unfortunately I can’t narrow it down any more than that for you.
