I'm looking for information on my furnace such as manufacture date and availabilty of manuals.

Sears model 867.763138, serial 94059480

As to age, I'd say it was made in early Feb. 1994. (94=1994, 05=fifth week)
The Sears number doesn't help me at all. Is there a manufacturers number on the sticker? Some Sears furnaces are made by a division of Carrier, others by a division of York, others by??

I was wrong on the model #. It is 867.763130. I did find a manufacturer # of S699511A. The 'S' may be a '5', I couldn't tell for sure.

Here's what I found on Sears Parts Direct: http://www.searspartsdirect.com/partsdirect/part-model/Kenmore-Parts/Furnace-Parts/Model-867763130/0582/0912130?pathTaken=&prst=0&shdMod=867763130
