Completed gas furnace replacement. Disconnected the old furnace and removed it from the basement. Set new furnace on blocks and then reconnected the electric, gas, pvc venting and ductwork. Installed a new T6 programmable thermostat and connected it to the furnace. Reconnected the furnace and humidifier drains. Run tested the furnace but will still need a technician start up.
