What vent does the 60,000 BTU 96% AFUE 2 Stage Goodman Gas Furnace use?

Both vent kits can be used with this furnace. The one you choose is dependent on how many elbows are needed for your venting setup, which dictates what the maximum allowable venting length is. A 2" vent kit has a much lower maximum venting length than a 3" kit, so usually the 3" kit is the safest bet. For more information, please refer to page 16 of the furnace's Installation Guide, found in the Resources section on the product's webpage.
