Completed gas furnace replacement. Disconnected and removed old furnace from the basement. Set new furnace on blocks and reconnected the gas, electric, AC drain and duct work. Re-worked the existing vent pipe to accommodate connecting the 4†RV pipe the new furnace vents with. Also reworked the water heater vent pipe to shorten and allow reconnection to our new RV tee.
