ProCom Dual Fuel Ventless Blue Flame Gas Space Heater with Blower

I'm clearing out this ProCom dual fuel ventless gas heater. It's a blue flame model that puts out 20,000 BTUs, which is plenty for a large room or garage. It can run on either natural gas or liquid propane. It's used but in good shape and includes the blower fan and some gas line hoses. Just don't need it anymore.
