The In-Forcer air injection arrived today via FedEx. This thing is much bigger than I thought it would be. I went out to Home Depot in the evening and picked up a 3 inch elbow and 10 feet of 3 inch pipe as well as a inch duct extension to attach to the unit. I went under the house and evaluated where the unit will go. I had to clear some insulation between two joists. The insulation is all coming down anyway. Dinner was a Bojangles chicken dinner.
