Where Can I Find The Lennox Serial Numbers
from web site
You can find the model and serial numbers (M/N and S/N) for your furnace by removing the top-front service panel and looking to the left side of the interior cabinet or the top of the blower deck, depending on whether your system is an 80% or 90% AFUE unit. Also, the orientation (horizontal or vertical) and flow direction (down or up) of your furnace may impact the location of the information.
Can anyone help me with the age of this LENNOX furnace, the only number I could find was GH60-0. Where do yo get your information on manufacture dates for heating equipment? I have a list for water heaters but can’t seem to find one for boilers and furnaces.
