Question About Lennox International Inc. Furnace G43UF-24B-045-08
Installation Manual...

I'm looking specifically for the direct vent piping limitations (max length, diameter) that the combustion fan can overcome. I'm finishing my basement and I need to relocate the flue vent and combustion air vent. Lennox only has owners/operators manuals on their website.
