The Master is a 140,000 BTU forced-air kerosene and diesel heater built to warm large open spaces up to 3,500 sq. ft. It runs on kerosene, #1 and #2 diesel, JP8/Jet A and #1 and #2 fuel oil, with a 10-gallon tank and a fuel gauge for up to 9 hours of run time. A built-in thermostat and air pressure gauge let you hold a set temperature, and a 5-point safety system cuts fuel on flame-out and shuts off on overheat. It suits garages, workshops, warehouses and job sites where a permanent furnace isn't practical; it is a loud, vented-space machine, not a quiet indoor room heater.
