Here is a brief description of how to read the model number and figure out the age:
"Lennox: Either the first two or second two digits are the year, it varies by era, but most of them actually have a separate sticker somewhere that has the year printed on it. Newer ones are first two equals manufacturing plant #, 2nd two are year and letter in fifth slot is month (A thru M minus I). So 5898G 07568 would be Plant # 58, Year of MFR would be 98 and month would be July."
There are some different styles as well so if this does not match the number you have send the model number and we can figure it out.
