I have a Dyna Glo 360° tank top 40 KLP heater. I also have a upright mobile craftsman toolbox that has been gutted and his open faced. I currently vent the propane heater by opening the attic door fully and cracking the bay door about 6 inches. I would like to use the toolbox as a makeshift “heater cabinet “ By placing the heater portion in the cabinet, separating the propane tank and venting the top of the cabinet-ducting outside. Leave attic door ajar for airflow and eliminate opening bay door. Can I do this without blowing myself up?
