We wanted to keep things simple and this is done by avoiding propane, diesel, and kerosene, the furnace runs on the same gas tank that operates the engine.
Airflow is 55 CFM. The volume of the van is just under 500 cubic feet meaning that the air will turn over every 10 minutes. A typical scenario has one or more of the Maxxair Ventilation Fans operating in conjunction with the furnace. This will heat the van, circulate fresh air and also remove moisture.
